Recovering the corrupted BKF file when the catalog files are missing

You must be knowing how important it is to safeguard your valuable data from several hazards. For this purpose, the Windows (NT and beyond) users have been provided the NTBackup utility that enables you to backup your crucial data from time to time. Using NTBackup, you can simultaneously create several instances of BKF files of different files and folders. However, sometimes the bkf files may get corrupt due to various reasons, such as virus infections, media read error, interruptions while creating the backup, etc. For the bkf recovery, you should use efficient an BKF repair tool.

Consider a scenario wherein you have to take create separate backup instances of different folders locations in your system. You run the NTBackup utility and create the backup. But when you run the utility again to restore the data, you cannot find the catalog files in the bkf files. These catalog files enable NTBackup to restore the BKF files. You may have successfully created the backup but still you may get the following error messages:

• The backup file contains unrecognized data and cannot be used.

• The backup file is unusable. You must erase it, or choose another file.

• An inconsistency was encountered on the requested media.

Cause:

NTBackup creates catalog files for every completed BKF file and stores it in the following location:

“SystemRoot\Documents and Settings\All Users\Application Data\Microsoft\Windows NT\NTBackup\catalogs51”

The catalog files are listed in the “Items to restore” section from where you can select the respective file to restore. When you create multiple backup at the same time, the catalog files share the identical “timestamp”attribute, which leads to ambiguity in the catalog files. As a result, the catalog files of the bkf files that are not created and, thus, are missing.

Resolution:

In this scenario, the bkf files get corrupted and you need to use a BKF repair tool for the maximum recovery of data.

Understanding this requirement, Microsoft has incorporated NTBackup utility in Windows NT and above working systems to produce a legitimate backup. The backup document utility is often saved around the pc or the network. In contrast to another file, this record may also be corrupted because of several logical corruption factors. A corrupt BKF file displays an miscalculation information in the event the person attempts to open it. This error message can make the info saved from the BKF record inaccessible. In such cases, if the user wishes to save the BKF file but no other backup is accessible, then the individual requires to fix the corrupted BKF document by employing an advanced restoration BKF repair software..

Consider a situation, where you attempt to open a BKF file, after you double-click within the BKF report, you view the under mistake information:

“[Unrecognized Media]
The backup report is unusable. You ought to erase it, or select one more document. ”

After the earlier mistake meaning appears, the saved data inside BKF record turns into inaccessible. Additionally, the very same error communication pops up each and every time you try and access the file.

Cause:
The above miscalculation communication primarily takes place in the event the format in the file has been modified someway. This problem occurs while you had been attempting to open the file.

Resolution:
To isolate the earlier miscalculation message and learn the data saved inside BKF report, you have to use an effective BKF repair software. An effective MS Backup Recovery software package guarantees full mend of a corrupted BKF file regardless of the diploma of its corruption.

Using BKF recovery software to repair damaged BKF file to restore backed up data

In our day-to-day life, we spend almost two-thirds of our time working on the computer system as it has invariably become an indispensable part of our life. We store all kinds of data including important documents, photos, videos, and what not on our computers. To safeguard the data though one must use some tool, like NTBackup that creates backups in the form of BKF files, to take backups on a timely basis, so that these could be used to restore the data as and when the need arises. However, sometimes you are unable to restore these files because of BKF corruption. In such cases, you should repair BKF file using a third-party BKF repair tool.

Let us assume a practical scenario in which you are in a habit of routinely adding your system data in a BKF file. One fine day, when you tried to restore the BKF file using the NTBackup utility after a fresh installation of the Windows 2000 operating system, you are unable to do so. The following error message is getting displayed, which is:

"[Unrecognized Media]
The backup file is unusable. You must erase it, or choose another file."

After getting this error message, you can only click on OK to close the message box.

Cause:
The most possible cause of such erroneous situation is that the BKF file is damaged and is, now, not in a valid Windows 2000 backup file format. Because of the BKF file corruption, the NTBackup utility cannot proceed further to restore the data from the BKF file.

Resolution:
To avoid such situations in the future, one precaution that you should take is to select the 'Verify Data After Backup' advanced option to make sure that the integrity of the BKF file is checked every time the backup is created. In this case, if you get errors after creating the backup then you have the option to recreate it unlike in this case when you seemed to have lost the data.

However, all is not lost as it may seem at the moment. The BKF file can be repaired and all the data can be restored using a third-party BKF repair software. Such tools are read-only in nature that do not overwrite the existing data while repairing the BKF file.

The best recovery software that enables you to repair BKF file from all instances of BKF corruption is Stellar Phoenix BKF Recovery. Having the capability to perform BKF recovery for the backup files created using NTBackup tool, this BKF repair tool also repairs the damaged BKF files created after using Backup Exec by Veritas software.

BKF Recovery in Server 2003 After Deletion of Archive Bit Information

It is imperative for a Microsoft Windows user to backup his/her file. Backup files turn out to be handy tools in the hands of a user in the unlikely event of data loss. Data loss could be due to varied reasons including system crash, virus attack, and many more. However, due to the presence of backups created with the help of these backup tools, no data loss situation can last forever. But imagine what would happen if these backup files themselves get corrupt. Backup files when created should be verified immediately to ensure they are in the right state, and work properly in any recovery case. But imagine what would happen if these backup files were to get corrupt. Then the user has to opt for BKF recovery methods.

Consider as a user of Microsoft Windows Server 2003, when you create backup in a BKF file, the NTbackup utility may just delete what is known as archive bit information. Every BKF file that is created in Windows operating system using the NTBackup.exe utility, has archive bit information that links to Windows file system. This archive bit information informs about the backup data that was stored previously. It determines the changes every time a complete backup is done. Further, on checking the advanced properties of the file, you'll find the check box in front of 'File is ready for archiving' deselected. If the 'Verify data after backup completes' check box is selected, then the problem occurs.

To resolve the above caused problem, Microsoft has a hotfix, which should be installed to get rid of the problem, next time you create a backup. But for the BKF files already created and damaged, you will need to repair BKF files.

For this you will have to install BKF recovery software. These are third-party tools that apply complex algorithms to repair any backup file that have been corrupted due to any reason. Capable of repairing files after any instance of damages, including CRC error, file system corruption, application malfunction, damaged header, or virus attack, these ms backup tool are completely risk-free due to their read-only nature.

Using a BKF Repair Tool to Get Back the Data From Damaged BKF File

In the current scenario, when there are lot many ways to lose our valuable computer data, one should look to safeguard it using various techniques. Few ways to do so is to use an updated antivirus, regular maintenance of the hard disk using system tools, keeping backups, etc. Of these, the best way is to take regular backups and keep appending them. In Windows systems, there is this NTBackup utility that allows you to create backup in the form of BKF files. However, these BKF files can get corrupt and it hurts the most when you have lost the original data. In these instances, using a third-party BKF repair software is the best option as it performs BKF recovery to extract all the data safely.

Let us assume that you have created backup of some data in Windows Server 2003 using a multiple-tape set. Because of this, the backed up data is situated in two separate backup sets, that too, on 2 distinct tapes. However, when you tried to restore the BKF file you are unable to do so. An error message is displayed as a result, which is:

"Error: An inconsistency was encountered on the requested media"

This problem particularly appears when you have try to restore the data from the second tape after restoring the data from the first tape.

Cause:

This issue appears when you are asked to restore from the incorrect set of tape. This problem specifically occurs when the backup sets are placed one after the other so that at times the required set is positioned on different members of the media set.

The other reason for such behavior is that the BKF file has become corrupt and, thus, inaccessible.

Resolution:

To fix this issue, you should make sure that you select one backup set and restore from that only at one point of time. Similarly, you can proceed with other backup sets as well.

Actually the backup sets are placed in the alphabetical order. But you can order them according to their set number identify them in a better way. Then, you can restore data from them in a sequential manner.

Having said that, at times this problem is not fixed using the aforementioned solution. In this scenario, the BKF file may have been damaged. To extract the inaccessible data from the BKF file, one should use a professional BKF repair software. These third-party tools use highly advanced but sophisticated scanning algorithms while retrieving the backup data.

How to restore BKF files from Windows 2000 using a USB drive

NTBackup is a utility in the Windows NT systems that is used to create routine backups of valuable data in the form of BKF files. You can take the backup in various modes such as differential, incremental, etc and in various storage media as well. However, sometimes the BKF files fail to restore leaving you in the middle of nowhere as you may not be having any other copy of the BKF file to rely on. Such situations can occur due to various reasons such as power outages, interruptions during backup process, virus infections, etc. In such cases, you should repair BKF file using a third-party BKF repair tool.

Consider a scenario wherein you have a Windows 2000 system. You are trying to restore a BKF file in a USB drive. But, you are not able to restore the BKF file as the following error message is getting displayed:

“Required Media Missing
The next media required in the active family is not currently on-line.
Please insert the media:

Name_of_backup_media, media #0

or click Cancel to stop the current operation.”

You get this error message even when you provide the correct media. When you click Cancel, then the following error message is displayed:

“Drive Error
The device reported an error on a request to mount the media.
Error reported: Unknown error.
There may be a hardware or media problem.
Please check the system event log for relevant failures.”

Cause:
One of the main problems for this situation is that you are trying to restore the BKF file using a USB tape drive that uses the USB storage driver (Usbstor.sys). When this storage driver is used, it faces the I/O queuing issues that result in failed restoration process. The other reason for this problem is that the BKF file is corrupt.

Resolution:
To resolve this problem, check if you have the copy of the data of which you took the backup. If yes, then you can use that data. Or else, you should download and install Windows XP Service Pack 2 as a hotfix for this problem. Now, try to restore the BKF file using the NTBackup utility.

However, if the BKF file is still not getting restored then chances are that the BKF file is corrupt. To restore the BKF file, you should use a third-party BKF recovery software to repair BKF file. These BKF repair tools are read-only in nature that do not overwrite the original data.

Recovering BKF file saved on multiple-tape set

NTBackup is an in-built utility in the Windows (NT, 2000, Server 2003, and XP) systems that is used to create the backup of all kinds of files and folders. It is an extremely useful utility that can be backed up to tapes, ZIP drives, floppy disks, and hard drives. It also provides seamless integration with Task Scheduler to enable automated backup of selected files and folders. However, as happens with most things, the BKF files are also prone to corruption. This can happen because of various reasons such as power surges, virus infections, incomplete backup process, etc. You can get the backup again if you have the data whose backup was created. Otherwise, you should use a third-party BKF recovery application to repair BKF file.

Consider a scenario wherein you have created a backup in the form of a .bkf file using NTBackup on a multiple tape set. When you try to restore the data, you are unable to do so and the following error message is displayed:

“Error: An Inconsistency Was Encountered on the Requested Media" Error Message with NTBackup.”

The error message signifies that the backup created on the tape has corrupted and is, therefore, inaccessible.

Cause:
The most possible cause for this error message is that the backup may have corrupted. It could have happened because of various reasons such as power surges, virus infections, corrupt operating system, problem in the storage media.
Another possible reasons is that as you have taken the backup on a multiple-tape set and the data is placed in two different backup sets on two different tapes. Sometimes NTBackup prompts you to mount the incorrect set of media to restore the data. This is also the reason why the error message is displayed.

Resolution:
To solve this issue, you should try to select and restore only from one backup set at one time. This would address the issue. However, if the issue is not resolved then you should use a third-party BKF repair tool to repair BKF file. Such read-only tools are capable of safe BKF recovery without overwriting the corrupt data.

How to Open Windows XP Backup File in Windows Vista?

NTBackup is a command-line tool included in Windows Server 2003, Windows XP, and Windows 2000 for backing up data on to storage media like, tapes, floppy disks, and ZIP drives. In Windows Vista and later operating systems, this tool has been replaced by Windows Backup and Restore Center. Unlike NTBackup, which uses BKF file format to backup data, Windows Backup and Restore Center uses its own proprietary file format - VHD (Virtual Hard Disk). Thus, you cannot directly open and access old backups created with earlier operating systems in Windows Vista. For BKF Recovery in Windows Vista, Microsoft provides a special tool, which has been mentioned further.

Before explaining the use of this tool, let's first consider a realistic problem. Suppose you use Windows XP and for future restoration purposes, you run NTBackup utility and store the backed up data on a floppy disk. Next, you perform a clean reinstall of Windows Vista and lose important data in this process.

Expecting that you can restore this lost data from the BKF file created in Windows XP, you insert your floppy disk in computer and try to restore the file. But you observe that you cannot restore this file and cannot regain lost data.

Solution
As mentioned, Windows Vista cannot restore the BKF file directly. To read and restore BKF files in Windows Vista (also in Windows Server 2008), Microsoft offers NTBackup Restore utility. This is a supplemental utility that can read backup file of Windows XP and Windows Server 2003 and allows its access in Windows Vista and Windows Server 2008 computers.

However, if even NTBackup Restore utility cannot read the file, it could be due to corruption of BKF file. To read such files, you need to take aid of a third-party utility to Repair BKF File.

BKF Recovery software are exclusive tools built for repairing and restoring the corrupted BKF file contents at a safe location. Once installed, you can safely run these applications and read corrupted file without any hassle. However, keep in mind that the utility you choose must be compatible with Windows Vista or any other operating system you use.

BKF Error: 'Access Denied' for Each File

Performing data backup is no doubt a preventive measure against data loss. But a user can fall in more disastrous situations when his/her backup fails to restore. Such situations are usually observed with Windows NTBackup file. This is a Windows built-in utility that uses BKF as its proprietary file format to create the backup. If corrupted, in most of the cases, Windows finds it unfeasible to recognize a BKF file and denies to restore it. In a rare situation, when a user tries to restore the BKF file, The BKF file is recognizable but not the included files. The following reading will give you some BKF Recovery action plans to deal with such problems.

Before explaining the causes and measures of this issue, let's make it more clear with a related example. A user creates a backup of some important files and folders using Windows XP backup utility. But when it comes to restoring them, the files cannot be restored. Running Restore utility for each of the included files gives the below error message:

“Access denied”

Cause
Some possible reasons for the above behavior to occur are listed underneath:

• You are trying to restore Windows XP backup in Windows 7 without using specific utility.

It enables you to create backups in the form of BKF files that can be restored in case of any emergency. Having said that, sometimes these BKF files too can get corrupt because of various reasons such as virus infections, CRC errors, inappropriate backup operation, etc. In such situations, you should use a third-party BKF repair tool to repair BKF file.

Consider a scenario wherein you are using Windows 2000. You are a member of the Backup Operators group and the Users group. You have created a BKF file in a new tape. Now, when you try to restore the BKF file, you are unable to do so. An error message is displayed, that is:

“This set cannot be catalogued because the media containing the set data is missing.”

Cause:
The root cause of this erroneous situation is that the members of the Backup Operators group do not have the required Control permissions of the library objects. These permissions are required by the NTBackup tool to perform data restoration. When the group does not have the permissions and a member tries to use the NTBackup tool, the backup media is rendered as incomplete and the error is raised. The other reason for this message is that the BKF file is corrupt.

Resolution:
To resolve this issue, you should assign the Control permissions to the Backup Operators group. This can be done by performing the following steps:

However, if you have lost or deleted the data then you should use a third-party BKF recovery software to repair BKF file. Such read-only tools are able to recover data from the BKF files using fast yet sophisticated scanning algorithms without overwriting the original contents.

Repairing corrupt BKF file from a tape drive

A tape drive is a storage device that is used to read from and write data to a magnetic tape. It is, basically, used to take offline and archival data storage. This is because the tape drives are very economical and can be used well for taking backups of huge amount of data. However, at times the BKF files that are created using NTBakcup utility in the Windows NT systems get corrupt when they are archived in the tape drives. In such situations, you should perform appropriate corrective methods to repair BKF file. However, if you are not able to resolve the situation then you should use a third-party BKF repair software to repair BKF file.

Consider a scenario wherein you are using Windows 2000. You are trying to restore a BKF file that you have taken in a tape drive. However, the following erroneous situations are occurring:
NTBackup displays that there is data in the tape drive but no files are shown.
In the Restore tab, you click the Catalog option and the following error message is displayed:
“The next media required in the active family is not currently on-line. Please insert the media name of the media in the drive.”

Cause:
The root cause of this situation is that you have created the backup in the same tape and another user has created a backup after you. Another reason for this situation could be that the BKF file has corrupted.

The NTBackup utility keeps the backup catalogs according to the users. This does not let you in viewing backups created by other users.

Resolution:
To resolve this erroneous situation, you should download the latest service pack for Windows 2000. After this, check if the situation is resolved. However, if the issue is not addressed then you should use a third-party BKF repair tool to do the needful.

This tool can prove to be very useful in case of data loss as you can restore the BKF files when the need arises to do so. However, sometimes it may happen that the BKF files themselves can get corrupt due to various reasons such as virus infections, human errors, CRC errors, etc. In such cases, you should use a third-party BKF recovery software to rectify the situation.

Consider a scenario wherein you have a Seagate USB 2.0 TR-5 Travan USB drive. Using this USB drive, you have created a BKF file in your Windows XP system. When you try to restore the BKF file, you fail to do so. An error message is displayed, that is:

“Required Media Missing
The next media required in the active family is not currently on-line.
Please insert the media:

Name_of_backup_media, media #0

or click Cancel to stop the current operation.”

And when you click Cancel to stop the current operation, the following message is displayed:
“Drive Error
The device reported an error on a request to mount the media.
Error reported: Unknown error.
There may be a hardware or media problem.
Please check the system event log for relevant failures.”

Cause:
This situation is caused if you create a BKF file in the USB drives that use the USB storage driver. The BKF files created in such drives cannot be restored.

Resolution:
To resolve this situation, you should try to again the take backup again if you have the data intact with you, this time without using that USB drive. If you do not have the data, then you should download the latest service pack for Windows XP. This should resolve the problem.

File Header Corruption Prevents you From Restoring BKF File

Microsoft Windows Operating system enables you to create backup of your valuable files to prevent data loss situations. MS Windows XP and earlier versions include NTBackup.exe utility backup your data from Windows hard drive and store it to desired location. In case system failure occurs, you can restore data from backup file easily. The backup is stored in the form of BKF file. However, in some situations, the BKF file gets damaged and you can not access its contents. In such cases, it becomes essential to repair BKF file to extract data out of it.

In a practical scenario of this problem, you may come across the below error messages when you try to restore your backup, irrespective of the partition type, either system/boot partition or non-system partition:

Type: Warning
Date and time: 12/6/2009 10:27:27 PM
Backup plan: Backup 12/6/2009 10:26:01 PM
Task: Simple backup task
Code: 10,551,337(0xA10029)
Module: 161
Owner: xxxxxxx
Message:
The header of the backup file is corrupt.
Additional info:

Error code: 41
Module: 161
LineInfo: 6b233907fd5acd9c
Fields: Volume : FAAA1.TIB, $module : C:\Program Files (x86)\Acronis\BackupAndRecovery\DiskBundle.dll
Message: The header of the backup file is corrupt.
After the above errors, the restore process gets interrupted. In order to resume the restore process, you need to find out the cause of this behavior and repair BKF by resolving it.

Cause
As stated in the above error messages, this problem occurs due to corrupt header of the backup file. Header is the most important component of every file. It contains significant file information, such as file type, file size, file location, and more. The problem can also occur due blocked access of backup file.

Resolution
In order to verify the file header corruption, you should validate the backup file. On the other hand, if blocked access is causing this problem, copy the file to another location and try restoring it.
If both of the above methods does not work, BKF recovery is the only way to go.
You can easily repair and restore damaged BKF file using third-party BKF repair tool. The applications help you to restore the file in a safe and easy way.

Restoring BKF files in case of missing catalog files

Almost everybody, who is using the computers, must have lost his or her data at some point or the other. Losing your valuable data can be very troublesome as you would have devoted you time, efforts, and money to collate it. This situation can well be avoided if the practice of backing up your data as a routine is followed. For the Windows NT (Server 2003, XP, and Server 2000) users, there is the in-built NTBackup utility, using which backups can be created in the form of BKF files. However, there are times when these BKF files, too, can get corrupt. This may happen due to various reasons, such as virus infections, improper or incomplete backup process, human errors, power outages, etc. In such cases, you should use a third-party bkf repair tool to restore data from the corrupted BKF file.

Consider a scenario wherein you have created multiple BKF files from various systems in your department. For this, you ran multiple instances of NTBackup and took the backup almost at the same time. Now, when you try to restore the BKF files you are unable to find one or more catalog files in the Restore tab.

Cause:
The root cause of this situation is that as more than two backup jobs were started at the same time, only the catalog file of the first backup job is displayed in the Restore tab. This is so because the multiple backup jobs share the same timestamp attribute as they were started at almost the same time.

Resolution:
As a workaround of this situation, you can perform the following methods:

• Login as a different user having permissions to restore BKF file. Then, create the catalog for the backup set from which you want to restore data. This way, the catalog file will be created in that user's profile.
• Remove all the existing catalog files from the Restore tab. And then, only create the catalog from which you want to restore from.

However, if you still are unable to restore data from the BKF file then you should use a third-party Microsoft backup repair software. Such tools are read-only in nature and repair BKF file by using fast and sophisticated scanning algorithms.

Backup file got corrupt?? Now Recover it!!

With technical advancements over the years, storage media are becoming more sophisticated and economical by the day. We spend so much on the these devices because we want a repository to store our ever-increasing data. And we all know that data is the most important part of our PC. So, one should take proper measures to safeguard this data as well. Windows (2000, XP, 2003 Server) users have the option to create backup of the data using in-built NTBackup utility. This utility enables you to take timely backups (in the form of .bkf files) using various modes. However, at times these .bkf files may get corrupt because of reasons such as human errors, power surges, interrupted backup process, virus infections, etc.
In such cases, you should look to replace the bkf file with its updated backup. However, if you do not have the backup then you should use a third-party BKF repair tool to repair BKF file.

Consider a scenario wherein you want to format your pen drive. You transfer the data to your hard disk and create a backup of the data using NTBackup utility. However, when you try to restore the data an error message is displayed:
“[Unrecognized Media]
The backup file is unusable. You must erase it, or choose another file.”

This error message signifies that the backup file is inaccessible.

Cause:
The most possible cause for this situation is that while the backup was in process, it may have gotten interrupted, and you did not confirm whether the backup was complete or not.

Resolution:
First things first, to avoid such slip-ups in the future, select the Verify Data after Backup advanced option. This would ensure that the backup is complete and the integrity of the backup files is maintained.

Then, if you still have the data for which you took the backup, then you can use the data. However, if this is not the case then you should use a third-party BKF repair software that will do the BKF recovery. Such tools are read-only in nature and do not overwrite the original data while scanning the damaged area.

Rectifying the CRC Error in corrupted BKF file

You must have gone through the pain of losing your important data due to various reasons. To avoid such situations, you should routinely backup your valuable data. For this purpose, the Windows (2000, XP, and Server 2003) users can use the NTBackup utility, which creates backup in the form of BKF file. These files are useful when you encounter data loss, data inaccessibility, drive corruptions, system malfunctioning, etc. However, even the BKF files can get corrupt because of various reasons such as virus infections, missing catalog files, media errors, CRC errors, etc. In such cases, you should recreate the backup. However, if you have lost the data itself, there is no possibility of recreating the backup. In such cases, you should use a third-party BKF repair tool to repair BKF file.

Consider a scenario wherein you have created a backup of a system over the network as you want to format it. After formatting the system, you run NTBackup to restore the backup. However, you are unable to do so. It seems that the bkf file has gone corrupt.

Cause:
The issue may have occurred because of the Cyclic Redundancy Check (CRC) error.

The CRC is used to validate the integrity of a data block. It is an error checking method in data transfer where a CRC character is produced at the transmission end. This character's value is dependent on hexadecimal value of all the 1s that are there in the data block. The error is a result of some of the bytes of the file getting lost or overwritten due to a random reason.

Resolution:
It is quite possible that you may have lost the data for which you created the BKF file. So, you would not be having the data anymore. To resolve this error you should contemplate using a third-party BKF recovery tool to repair BKF file. Such read-only tools are highly interactive and do not overwrite while scanning the damaged area using fast yet sophisticated algorithms. These tools do no require sound knowledge to perform BKF recovery of corrupted BKF file.

Repair BKF file created by Backup Exec

Backup format(BKF) Microsoft Tape Format or MTF basically tends to back up files. Files can be backed up to tape, ZIP drives, floppy disks, and hard drive. What if those created BKF file gets corrupted then in this case BKF Software which is an effective backup repair tool; is used to repair BKF files that are inaccessible or fails to restore. So, one should employ appropriate measures to safeguard the data. One such measure is to create timely backups of the data. There are many utilities using which you can take backups on a routine basis. Backup Exec from Veritas is one such utility that enables you to create backup in the form of BKF files. However, even these files are prone to corruption and you may not be able to restore the backup. In such cases, you should again create the backup. However, if you have lost the data before realizing BKF file corruption, then you should use a third-party BKF repair tool to perform BKF recovery.

Consider a scenario wherein you have created a backup of some files on your Ultrium 3 tape using Backup Exec software. Then, after a week or so, you try to restore the BKF file but not able to do so. An error message is displayed, that is:
“Unable to create selection list.”

You are able to restore other backups in the tape, but not able to restore this specific one.

Cause:
The most possible cause of this error message is that the catalog of the backup file has corrupted. The reasons for this behavior could be database corruption or media label conflict within the catalog. The BKF file can get corrupt due to various reasons such as human errors, virus infections, incomplete or improper data backup process, etc.

Resolution:
First of all, if you have the original data then you should create its backup again. However, if you do not have the original data or you have deleted it then you should use a third-party BKF repair software to repair the corrupted BKF file. These tools are highly interactive and read-only in nature, and ensure that no data is lost while scanning the corrupted file.

Repairing Backup file after NTBackup Drive regulate Messages

Microsoft NTBackup utility generates some verify messages “the backup file (.bkf file) is corrupt” after you complete the backup process.While running any server version of Windows, you can see these verify errors in the Application Event Log. It is highly recommended to consider the error messages and take corrective measures as soon as you bump into them, else the backup file can not be restored due to corruption. However, to fix the corruption of such corrupted BKF files, various BKF Repair softwares are available in market.

The further scenario illustrates a suitable situation when you can encounter such drive verify errors. Let's say, you use the NTBackup command-line tool and select 'Verify After Backup' option. When the backup is done, viewing the Application Event Log prompts you the following event:

ID : 8009
Source : NTBackup
Type : Error
Category : NoneDecription : End Verify to 'C.'

NTBackup reports the above event when it observes some differences in the data on original and backup destination.

Note: Similar type of event can also occur as informational message with Event Type as 'Information'. This happens when NTBackup doesn't find any differences in data on original and backup destination.

Explanation:
Event 8009 with type 'Error' can occur because of two main reasons:

• There have been some changes in original file(s) after the backup has been completed.
• Backup file (BKF file) created by NTBackup utility is corrupt and will not restore.

Checking backup reports is therefore a suggested action to ensure the consistency of backup file and to have error-free restoration. For detailed information about the cause, you can check the Backup.log file.

In case, few files have been deleted, edited, or added, or the backup file is corrupt, you can start another backup process. But if you ignore these errors, the result can be incomplete restoration. However, if the BKF file is corrupt, you can use a MS BKF Repair Tool. A BKF Repair software can scan your corrupted BKF file and restore the file contents to a safe location.

Recuperation BKF file using variousVSS Server

There is a backup utility tool so called NTBackup utility in the Windows operating systems such as Windows Server 2003, XP, and 2000 which helps you in creating backups of your remarkable data in the form of BKF files and in case of backup file corruption one can use this tool and get it recovered using the Restore Wizard. Using this tool, backup can be restored on floppy disks, zip drives, magentic tapes and hard drives. Sometimes BKF files may get corrupt due to various reasons such as corruption in storage media, virus infections, power surges, human errors, etc. In such cases, one should have backup of the their data. However, if you have lost the data then this third party tool so called BKF repair tool can be taken in use to perform BKF recovery.

Consider a scenario wherein you have a Windows XP system. You have created a backup of your hard disk as you are about to format it. After formatting it, you try to restore the backed up data. You are unable to do so and an error message is displayed, that is:
“Backup Status
Operation: Backup
Active backup destination: File
Media name: "bkup_file.bkf created MM/DD/YYYY at HH:MM AM|PM"
NTDS has reported a VSS error 0x800423f0...”

The BKF file has corrupted and, thus, is inaccessible.

Cause:
The root cause for this error message is that the BKF file created in the Volume Shadow Copy (VSS) server interface has corrupted. The reason behind this is that the VSS server acts differently in both 32-bit and 64-bit versions of Windows operating system. A BKF file created in the 32-bit VSS interface needs a 32-bit VSS-based backup tool to restore the backed up data. Therefore, for appropriate restoration one needs to have the operating system, database, and the catalog files on the same volume. However, the aforementioned error message is displayed when either of the volume is on the system drive, which apparently leads to corruption of the BKF file, thereby accounting for restoration failure.

Resolution:
Windows may not provide you any method to repair BKF file. So, this third-party BKF repair tool can be used to repair the corrupt file for BKF recovery. Such read-only tools are able to repair BKF file without damaging the original contents.

Repairing corrupt BKF file from multiple tape set

Most of you must have faced the agony of data loss due to sundry reasons. In such situations, a lot of people crib over not having a tool to take timely backups of the valuable data. Well, the things are not so terrible actually. For those who don't know, Windows (2000, XP, and Server 2003) users can use the NTBackup utility that enables you to take the backups in different modes such as differential and incremental modes. The backups, using NTBackup, are created in the form of BKF files. However, sometimes these BKF files too can get corrupted. In such cases, you should take appropriate corrective measures to solve the issue. However, if you are unable to do so then you should use a third-party BKF repair tool to repair BKF file.

Consider a scenario wherein you have taken the backup of some data in a multiple-tape set. The backed up data is located on two different tapes. When you try to restore the BKF file, you are unable to do so. An error message is displayed, that is:
“Error: An inconsistency was encountered on the requested media”

This error message is displayed when you restore the BKF file from the first tape, and start restoring the data from the next tape.

Cause:
The cause of this error message is that NTBackup prompts you to mount the incorrect piece of media to restore the backup from. Stated problem occurs when backup is appended innumerable times to make it reside on different members of a media set, not for a single backup set spanning a number of media.

Resolution:
To address this issue, you should select and restore and BKF file from one backup set at a time. This should resolve the problem. However, if you are still not able to resolve it then chances are that the BKF file is corrupt and, therefore, inaccessible. In such cases, you should use a third-party BKF repair tool to repair BKF file. Such read-only tools use fast yet sophisticated scanning algorithms to perform BKF recovery without overwriting the original data.

Cannot Restore Backup

Some computer users have the habit of taking daily backups of their data. To help these users, Microsoft provides an inbuilt backup utility (NTBackup) in Windows operating system. The utility allows the users to create a backup of all or selected files, and save it on the network or personal computer. The utility also allows the user to restore the backup at the desired location. However, there are certain situations where the utility fails to restore the data backup. Such situations occur when the backup file gets corrupted or damaged. In such cases, the backup file needs to restored from another valid backup. But, if that file is also corrupted, then the user needs to repair the corrupted backup file by using a commercial repair BKF file.

Consider a practical case where you create a backup file – using NTBackup utility – that contains all your accounts-related files and folders for previous year. You save the file on the network drive and delete all the files from your system. However, the next time when you attempt to restore the file, you view the below error message:
“The backup file contains unrecognized data and cannot be used.”
After the above error message appears, all your previous year's accounts files and folders become inaccessible. Moreover, the same error message appears, regardless of the times you try to open the file.

Cause:
The restoration of the BKF file fails due to the corruption of the file. Few causes for BKF file corruption could be header damage, media read/write error, virus hit, and CRC (Cyclic Redundancy Check) errors.

Resolution:
To access the BKF file post corruption and to access the financial records, you will need to follow the below steps:

• Use a copy of BKF file and perform restoration at your desired destination.
• However, in case of unavailability of BKF file backup, you will need to repair the corrupted BKF file by using a powerful BKF Repair tool. A MS Backup Recovery application scans, repairs, and restores the BKF file, irrespective of the cause of its corruption.

Extracting Corrupt BKF File from a CD or DVD

Windows NTBackup utility is the backup system included in Windows 2000, Windows XP, and Windows Server 2003 operating systems. Originally, NTBackup has been designed to create and store scheduled as well as automated data backup to storage media like, Zip drives, floppy disks, and tape. But a third-party add-on called Firestreamer-RM extends its capability and makes it support various other storage media, including but not limited to CDs and DVDs. NTBackup files (BKF files) stored on these media are often observed as corrupt at the time of restoration. There are many user reports that state the corruption of BKF file, detected when the file was stored on a CD. Such circumstances necessitate the use of a well-designed MS BKF Repair Tool.

The above problem will be more clear by a corresponding real-time issue, described further. Consider a case of Windows user who uses Windows NTBackup utility to backup few important files on a CD. The files are critical and are required for a business deal. The user then deletes the original files from the computer to solve some system-related concerns and expects to restore them using the CD stored backup. However, when he/she tries to restore the BKF file, it seems to be inconsistent. Each time, when he/she attempts to restore the BKF file, it prompts the following or a similar error message on screen:

“The backup file contains unrecognized data and cannot be used.”

Note: With the creation of each BKF file, NTBackup creates a log file in NTBackup data folder that among other information, consists of the status of backup process. To prevent such problems, make sure that you check the consistency of your backup file after performing the backup itself.

Data Retrieval:
To retrieve the lost data, you can either use another copy of your lost files and folders, if available. If no such copy exists, you need to use a third-party Backup Repair Tool to repair and restore corrupted BKF file content. A MS BKF Repair Tool can scan corrupted NTBackup file and repair it while retaining its original integrity.

BKF File Corruption: Reasons and Solution

Nothing can be more frustrating than an inability to restore data despite having a good backup plan. There have been many instances, in which users report that they find it unable to restore data with the BKF file created by NTBackup.exe utility. Unlike your expectations, Windows backup utility might fail to offer data restoration because of a corrupted BKF file. When you try to restore using BKF repair tool, an error message may appear suggesting that the file has gone corrupted. Below are some typical reasons that are often found responsible for BKF file corruption:

BKF file format was designed long time back, but not with the specific purpose of storing high amount of data that we need today. Thus, it is recommended to keep the file as small as possible. A large BKF file is prone to corruption.

Users, more specifically home users, opt for low-priced backup storage devices (like, USB, FireWire devices, etc.) without caring for their reliability. As a result, the backup media can record faulty data that have been transmitted to them (even if transmitter from a reliable hard disk). This issue is the prime case of single bit errors in NTBackup BKF file.

Being removable, a backup storage media is susceptible to virus infection. These media are frequently used and accessed on computers that might be infected from fatal viruses and have potency to corrupt the BKF file. So, scan your computer for viruses before inserting the backup storage media.

Events like unexpected power outage are also known to cause BKF file corruption. While interrupting the data writes, power failure can render your BKF unrecognizable in Windows.

You have two main options to deal with such problems. Either you can use another copy of lost files and folders to restore data or you can use a MS Backup Repair Tool to repair BKF file. You can find many third-party utilities on the internet, that might help you to restore lost data from corrupted BKF file created by MS Backup Tool

Recovering BKF file in case of missing catalog files

The NTBackup utility is used to create backups in the Windows operating systems such as Windows Server 2003, XP, and 2000. It is particularly helpful when your system is somewhat unreliable and you fear that it may crash anytime. The backup is created in the form of BKF files. However, at times the bkf files can get corrupt due to various reasons such as human errors, virus infections, power surges, incomplete data backup process, missing catalog files, etc. To overcome such situations, you should take appropriate corrective measures. However, sometimes these measures are not adequate. In such cases, you should use a third-party BKF repair tool to repair BKF file.

Consider a scenario wherein you took concurrent backups of several locations simultaneously. When you wanted to restore the file from back up of the data, you were unable to do so. You were not able to view the catalog files in the Restore tab. These catalog files enable NTBackup to restore backed up data from the BKF file. This is apart from the fact that the backup operations are completed without displaying any error message. But when you try to restore the backup, an error message is displayed, which can be any of the following messages:

The backup file contains unrecognized data and cannot be used.
The backup file is unusable. You must erase it, or choose another file.
An inconsistency was encountered on the requested media.

Cause:
The main cause of the problem is that the BKF file has become corrupt due to any of the aforementioned reasons. One of the reasons can be that there are missing catalog files of the backed up data. The catalog files are stored at the following location in your system:

%SystemRoot%\Documents and Settings\Account\Local Settings\Application Data\Microsoft\Windows NT\NTBackup\catalogs

What happens is that when you create more than one backup simultaneously, the catalog files share identical timestamp attribute. In this case, the backup set that was attributed first was displayed in the Restore tab and other backups were sometimes not displayed in the list. Because of this, the BKF file got corrupt and you had to perform BKF recovery to repair BKF file. This should be done using a third-party BKF repair application. Such read-only tools employ fast yet sophisticated algorithms to scan the damaged area.

Error Copying Windows BKF File from CD

Windows NTBackup is a built-in command-line utility of Windows operating system that can be used to backup files to different storage media like, CDs, DVDs, ZIP drives, tapes, and others. But many times, this is observed that storage media problems often corrupt the BKF files created by NTBackup program. So even if you verify the backup, further media malfunctions can cause damage to the file. In such cases, data recovery is possible only if you have another backup to restore or apply a BKF Repair tool that can repair the file.

As an instance of these problems, let's consider a scenario in which you create a BKF file on a CD using Windows XP NTBackup application. For avoiding any further problems, you verify the backup and expect it to work at the time of restoration. After a major data loss event, when you try to restore data from the CD stored BKF file, it behaves contrary to your assumptions and shows file corruption symptoms.

Further, when you try to copy the same BKF file from the CD to your hard disk, it pops up another error message that reads:

“Error copying file or folder
Cannot copy backup_file_name.bkf : Data error (cyclic redundancy check)”

Explanation
CRC or Cyclic Redundancy Check is a bit, which is used to ensure the integrity of data in a file when it is being transferred. It is a typical check procedure that can determine whether or not the data has been damaged. CRC errors usually indicate that the file being read by the computer is corrupted.

Note: Apart from software issues, the above error can result if the CD being accessed is damaged.

User Action
To restore the lost data, check for an alternative source. If available and valid, use this source to regain the lost data and discard the corrupted file. However, if no other solution is available, use a third-party BKF Repair Tool to diagnose and repair corrupted Windows backup file. BKF Repair programs are user-friendly applications that facilitate easy and efficient BKF file repair using high end procedures, while keeping the original data intact.

Recovering corrupted BKF file from external hard disk

I guess you must have faced loss of your precious data sometime or the other. And you would definitely agree that it is really frustrating to lose your data, which you may have maintained for years. Probably things would have been in better shape had you backed up your data. For this purpose, the Windows (2000, XP, and Server 2003) users have the option to backup the data using the in-built NTBackup utility. It saves the backup in the form of .bkf files and can backup from the tape, ZIP drives, floppy disks, and hard drives. However, these BKF files too can get corrupted because of virus infections, power outages, human errors, CRC errors, etc. In such cases, you should check if the original data is available. If yes, then you can create the backup again. However, if you do not have the data with you then you should use a third-party BKF repair tool to repair BKF file.

Consider a scenario wherein you have a hard drive that has just gone dead. You replaced the hard drive with a new one. You used to backup all your data in an external hard disk using incremental backup mode. Now, when you try to use that backup to restore lost data you are unable to do so. An error message is displayed:

“The data file contains unrecognized data and cannot be used.”

The error message clearly suggests that the BKF file is inaccessible.

Cause:
The root cause of this issue is that the BKF file is corrupt. It may have gone corrupt because of the aforementioned reasons.

Resolution:
Now that you do not have the original data with you, the only thing that you can do in such situation is to use a third-party BKF recovery tool to repair BKF file. These read-only tools are highly interactive, and use fast yet sophisticated algorithms to scan the damaged area.

Restoring BKF file in Windows 7

With the technical advancements, we are opting for better computer systems and operating systems. That is precisely why, we switch to technologies that are sophisticated yet simple to understand and use. Following similar pattern is Windows 7, which is graphically advanced and very robust as compared to its predecessors. Because of this, the users of older Windows operating systems such as Windows XP, 2003 Server, etc have migrated to Windows 7. The users of Windows XP and earlier versions can backup their data using NTBackup utility, which backs up data in the form of BKF files.

However, when you restore BKF files in Windows 7 (or Server 2008) you are not able to do it. The reason for this is that Windows NTBackup utility has been discontinued in Windows 7. So, the BKF files are not recognized in Windows 7. Hence, these backup files are of no use in Windows 7, since you are not able to restore data with them.

However, there is a way-out for Windows 7 users. Windows has provided NTBackup – Restore Utility that is used to restore the backups that were created in Windows XP and earlier versions. You can also download it from the following links:

http://www.microsoft.com/downloads/details.aspx?FamilyID=7da725e2-8b69-4c65-afa3-2a53107d54a7&DisplayLang=en

Consider a scenario wherein you have switched from Windows XP to Windows 7. You have taken a backup of all your data using NTBackup. When you try to restore the BKF file in Windows 7, you are unable to do it, even though you have downloaded the NTBackup – Restore Utility.

Cause:
There could be two reasons for this situation.

• The NTBackup – Restore Utility feature is not enabled in the system. For those who do not know, this feature is disabled by default.
• The BKF file is corrupted and you need to repair BKF file using a BKF repair tool.

Resolution:
To overcome the first situation, you need to enable NTBackup – Restore Utility feature. This can be done by following the underwritten steps:

• Open “Programs” by selecting Start | Control Panel | Programs.
• Click “Turn Windows Features on or off”.
• Provide the password, if prompted.
• Select the Removable Storage Management check box.
• Click OK.

In the second case, try to restore the BKF file by accessing Ntbackup-RestoreUtility from Start menu -> All Programs. However, if you are still not able to restore it, chances are, that the BKF file is corrupt. In this case, you should use BKF recovery tool to be able to restore it.

NTBackup Cannot Detect Windows XP Backup File Corruption

Performing a scheduled data backup is one of the best practices against an unexpected data loss. NTBackup, the Windows built-in backup utility, helps Windows users in this respect by offering some advanced features like no other utility can. This tool is a part of Windows versions like, Windows Server 2003, Windows XP, and Windows 2000 and creates BKF files, which store all the required valuable files and folders. After you run a backup schedule using NTBackup, it is recommended to run a verification pass to determine the validity of your backup. However, due to some limitations of NTBackup utility, sometimes the BKF file corruption might go undetected. Consequently, when you try to restore the data from backup, it might report errors indicating that the BKF file is corrupted. Since there is no Windows utility to repair such corrupted files, the only solution to extract data from them is to use a BKF Repair tool.

Before explaining the method that NTBackup employs to check the integrity of BKF files during verification pass, let's first consider a realistic situation in which such problems can occur. Suppose you are a Windows XP user who uses NTBackup utility to create backup of relevant files. As a precaution measure of file corruption, you run the verification pass by NTBackup and it reports the BKF file fine.
A data loss event occurs and you have no alternative other than the BKF file to restore files. But contrary to your expectations, BKF cannot be restored. On trying to open the file, it gives the below or similar error message indicating file corruption:
“The backup file is unusable”
Reason of this behavior
NTBackup implements checksum comparison method using word-wise XOR operation (eXclusive OR) to find out the reason for corruption in BKF file. It fails to detect file corruption if corruption exists at the same location in a word and the number of times it occurs is even. As a result, when you try to restore a BKF file, although it has passed verification by NTBackup, it is reported as corrupt.
Solution
Use a third-party tool to Repair BKF File. These are exclusive BKF Repair applications available for scanning and repairing a corrupted Windows NTBackup BKF file, irrespective of the cause of corruption.
