A small analysis on BKF file corruption and possible ways to perform BKF recovery

In an organization, the data grows exponentially. Every bit of it is important as you have spend your most valuable time, invested a lot of resources and money, and put in your earnest hard work. If this data gets lost, then all your efforts will go in vain. Even a temporary inaccessibility of data may cause a serious loss to your business.

Data loss can occur due to numerous reasons, such as computer viruses, software corruption, hardware malfunction etc. Backup provide data security in all the above mentioned instances of data loss. Windows operating system uses an built-in utility NTBackup to perform the backup task for its users. Using this tool, users can even schedule backup operations at regular time periods. It creates a BKF format file to store the confidential backed up data. Sometimes these BKF files become corrupt and cause the data restoration process to fail at the time of a system or hardware crash. To overcome the problem, you need to go for BKF recovery through a reliable third-party utility.

For instance, when you try to restore data from a BKF file using the NTBackup tool on a Windows XP-based computer, you may come across the following error message:

“An inconsistency was encountered in the requested backup file”

Cause:
The BKF file may be corrupt due to anyone of the following reasons-
Virus or malware infection
Improper system shutdown
Header corruption
Missing catalog files
Application malfunction

As a consequence, the NTBackup utility is unable to recognize the BKF file. This would prevent you from restoring your precious data from the backup. In such circumstances, follow the below given resolution steps to perform BKF repair of the corrupt file.

Resolution:
To resolve the issue, you should take help of an efficient BKF recovery software. These software are comprehensible and easy-to-implement. They first search for the BKF files in the system and then scan the selected BKF files for recovery. They provide users an option to save the scan information which can be used to perform recovery at any later stage. Moreover, they can automatically install the latest software updates from the Internet.

The software can repair corrupt BKF files created using NTBackup utility or Backup Exec by Veritas Software. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

BKF file decomposition post Virus attack

A computer virus is an infectious agent that can replicate inside the network file system or file system and exploits secured vulnerabilities which may harm the data saved on the hard drive. A virus spreads itself automatically through networks and competent enough to delete or corrupt any file, even if it is backup file. In case, If backup file gets corrupt then it becomes very difficult for user to access the data which was saved in that file. A corrupted BKF file can be identified easily as corrupt file shows some weird characters instead of original data at the time of opening the same file. In such situations, If you wish to access the data saved in BKF file, you need to restore the data from another backup. Since backup of all the data is saved in BKF file so there is least probability to have another backup of same file. In such cases, you must use a third party BKF repair software.

Few most common viruses that corrupt your BKF files are Scores, Rabbit, ILOVEYOU, Egg, INIT1984. All virus owns few limitations to destroy BKF file. When your backup file is corrupt you may find:

Either,
The file doesn't allow to display the data at all.
Or,
The file will be displayed with decrypted characters

To abstain BKF files from being affected by a virus attack, you should always follow the following corrective measures:

Always keep a updated anti-virus software in your system.
Before you attach a hardware to your system, check properly whether the file is virus free
Always scan the files which are intended to be downloaded from Internet.

However, if the BKF file is already corrupted, then you must go for third party BKF Repair software to repair corrupt BKF file.

A Backup repair tool uses such an advanced scanning algorithm which thoroughly scans the corrupt BKF file and saves the recoverable file at user-specified location. The file repair tool is just do-it- yourself tool that makes it easily accessible without any before handed technical knowledge. This tool is completely non-destructive and does not harm the original data.

And is compatible with Windows 7, Vista, XP, 2003 and 2000.

How to recover BKF documentation corruption

One of the most secure technique to save your files in any logical or physical corruption state of affairs is by making use of an up-to-date backup file. 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. This repair bkf file utility may be simply utilized by any consumer (even by individuals with non-technical background) as it truly is straightforward to understand and implement.

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. In addition, this recovery software is compatible with various versions of Windows operating systems including Windows 7, Vista, Server 2003, XP, and 2000.

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.

Rectifying Error e00084b7 while restoring corrupt BKF file in Backup Exec

In today's world, it is very important to secure your computer data as you may never know how you would lose your data. So, there are several utilities that enable us to safeguard our valuable computer data. Two of these utilities are NTBackup from Windows and Backup Exec from Veritas software. These tools create backups in the form of BKF files that can be restored when the need arises. However, even then at times you find yourself in the middle of nowhere when these BKF files get corrupt thereby become unable to restore the data. Such BKF corruption can occur due to various reasons such as virus infections, interruptions while creating backups, CRC errors, etc. In such situations, you should find out the exact reason of corruption because the corruption may not be there. However, if nothing succeeds then you should use a third-party backup repair tool to repair BKF files.

Consider a scenario wherein you have backed up some data using Backup Exec 11D. Now, when you want to restore the data, it fails to do so. An error message is displayed as a result, that is:

"e00084b7 - a backup set was created which contains no data."

Cause:
There could be the following causes of this error:
• You are trying to restore from an offline media.
• The BKF files are being restored from another location.
• The BKF files have corrupted due to any of the aforementioned reasons.

Resolution:
To resolve this problem, you should create a new B2D (Backup to Disk) folder if the BKF files have been transferred to another location. Because of creating the B2D folder, the BKF files will again mount the online media again. Now, you can carry out the data restoration task.

However, if the BKF file is still not able to restore the backed up data, it means that the BKF file has corrupted. In such situations, you should use a third-party BKF repair software to repair BKF files. Such BKF recovery tools are read-only in nature and possess rich user interface that ensures safe and secure recovery of the valuable 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.
• An anti-virus software is running that is preventing the files from being accessed.
• BKF file is corrupted.

User Action
The corresponding solutions are as follows:

• Download and install Windows NT Backup Restore Utility for Windows 7 and use it to restore Windows XP backup.
