Recovering data from corrupt .BKF file

Data-BackupMS Backup files .BKF are created to backup all valuable files and folders, so that in times of corruption the bkf file could be used to restore all lost files and folders. Windows’ NTBackup utility is used to create BKF files for backing up the data.

But what will you do if BKF file itself gets corrupt? Trouble must say. Backup files are the only option for restoring inaccessible or deleted or lost files. And when BKF files play spoilsport, the situation worsens.

Consider a situation when you try to restore your files from existing BKF file. But, you notice that the files are not getting restored properly instead you encountering error messages. In short, backup file is not able to provide with restoration of backed files & folders. However, this situation is best tackled with BKF File Recovery tool, which repairs corrupt BKF files.

Let’s have a look at the reasons behind inaccessibility of .BKF file.

  • A third-party backup software has set the below mentioned value to 1 while getting installed. But, the NTBackup utility sets it to 0.

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Ntbackup\Backup Engine\Backup files inuse”

  • Another main could be missing files from the .BKF file. This happens when the value of the above mentioned entry is set to 0, the backup utility skips the open files, as a result of which some files might be missing while restoring from the .bkf file.

For resolving this issue, you need to set the following value to 0.

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Ntbackup\Backup Engine\Backup files inuse.

Secondly, make sure that the file is consistent before you backup.

If above steps are being executed then most probably backup file .bkf becomes accessible. But if it’s not working, that means level of corruption is quite high. This can be tackled only with proficient BKF Repair tool. The software repairs corrupt backup files make it appropriate for use by individuals who need to recover data from corrupt or inaccessible BKF files.  Please visit here http://www.bkfrepairtool.org/

How to recover data when NTBackup cannot restore data from bkf file

NTBackup is a simple utility that is built in with Windows 2000, Windows XP and Windows Server 2003 Operating Systems to back up and restore data. Microsoft, the developers of Windows has replaced NT Backup with another utility named Windows 7 File Recovery (or Windows Backup and Restore Centre) in later version of Windows. And in Server Operating Systems starting from Windows Server 2008, a facility named Windows Server Backup has been introduced for backing up and restoring data.

When you need to backup data or needs to restore data from backup, you can open this tool through Accessories > System Tools from the Start Menu of the Windows. Alternately, you can run ntbackup.exe in the Run prompt or Command line.

NTBackup utility saves files to disks, tape drives and ZIP drives in BKF format and restores files from the backup when required. Sometimes, when you try to restore the data from the NTBackup, you may receive the message ‘The backup file contains unrecognized data and cannot be used.’ And you won’t be able to access the back up the files. It means that your backup files are corrupt. Then how can you restore your data?

Backup file corruption can happen due to many reasons such as: issues with ownership, mapping or permissions, and accidental system shut down at the time of backing up the data or accessing the data. It can happen due to the deletion of archive bit also. On Windows, when a file is created or modified, a file attribute named ‘archive bit’ is set. And when the file is backed up, the archive bit is cleared. Thus by looking at the status of the archive bit, one can say whether a file is backed up or not. Sometimes archive bit may get deleted due to some problems such as corruption, virus attack or some other error. In that case you won’t be able to restore backup files backed up by the NT Backup.graph

You cannot restore data from corrupt backup files using the NTBackup utility.  Even the System Restore utility of Microsoft Windows won’t restore backup files. So you will have to depend on third party software like Kernel Recovery for BKF for restoring the backup files. Kernel Recovery for BKF is a professional tool for the recovery of BKF files from the backup created by NTBackup. Depending upon the depth of corruption, you can use either the Quick mode or Advanced mode of this tool to recover the backup files. It allows the user to save the recovered files in any location of his choice. Kernel Recovery for BKF works with most versions of the Windows operating system. The trial version of this software can be downloaded from its website for free to know more about it. Visit here http://www.bkfrepairtool.org/

Adapt an Expedient way to treat the Backup (BKF) file corruption

Backup2 According to a famous saying, “Prevention is better than cure”. Considering this fact, it is always good to maintain a backup of the important mailbox data and system data so that if any mishap occurs that result in data corruption then the data can be recovered from the backup and loss of data can be avoided. But, to your surprise, even this backup data is prone to corruption. The backup (BKF) file is also maintained on the system itself; therefore, just like other data even the backup data can undergo an unfortunate mishap. There could be numerous reasons for backup file corruption. Some of which are:

Causes which could corrupt Backup file:

  • Abrupt system shutdown
  • Media Malfunction
  • Virus intrusion such as Trojan or spyware
  • Manual error
  • Hard disk failure
  • Accidental deletion of database

Consider a real-life situation where you open your computer and suddenly it shuts down abruptly. Unwillingly, to bring the situation back to normal you had to format the disk. But since you have a back-up of the data maintained on your system, there was a sense of relief in your mind. After the successful formatting, when you re-start your system and open the back-up file to recover the data, following error message pops up:

error

“[Unrecognized Media]

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

Get acquainted with the solution to handle the BKF file corruption

An individual who depends on computer for either professional or personal work knows the importance of backing up the data. Maintaining a back up and safeguarding the database is very important since any mishap such as virus attack, accidental system format, etc does not knock the door of the person before arriving. Therefore, as a prevention measure professional individuals follow the practice of creating back up file (BKF) on daily basis and the personal users do it on a regular interval of time.

On any random day, imagine the situation that you somehow loose your computer data. When attempted to access the backup file unfortunately you last up encountering that it is not getting accessed. All the efforts put in by you appears to go in vain despite of taking the prevention measures. The reason behind this acerb fact is that BKF file is also prone to corruption or damage just like any other data file.

The above-mentioned issue will get clearer by considering a real life scenario experienced by a user. Suppose that a user works on a Windows Server 2003 system and due to its slow performance, he wants to format it. So he take backup of his data on external media but as soon as he attempt to re-install the data after formatting the system, he encounters a system generated error message:

“An inconsistency was encountered on the requested media”

The probable reason of such error could be that the media being used is in an unmountable state which is not allowing the user to recover the data or the BKF file has gone corrupt. It is generally seen that when the BKF file gets corrupt the character in the file turns to non-readable form or the BKF file does not open or the database in the BKF element cannot be displayed. In order to avoid BKF file corruption, it is recommended that if the system is virus infected then attempt should not be made to install the file from BKF, antivirus of the system should be up-to-date and any file downloaded from the internet should always be scanned.

However, if despite of taking preventions you come across BKF file corruption even then there is nothing to get worried for. It is because the BKF recovery tool works as a cure to the problem. Kernel for BKF is one such BKF file recovery tool designed in a way which provides user-friendly and interactive feel to the user. It efficiently repairs the corrupt BKF archives and databases to recover the EDB, STM and Log files from them. Moreover, provides you the capability to handle error issues like CRC errors, virus attacks, backup interruptions, errors like “Fails to open file “ or “The backup file is unusable”[Unrecognized Media].

Recover BKF files when it refuses to restore data

As insurance saves our lives from sudden disastrous loss, backup also helps in compensating the loss of system data from fatal data disaster. Users can get instant relief from the pain of losing important and crucial system as well as personal data if backup is available. But situations turn cumbersome when backup files become lost from Windows operating system. Users often face the problem of backup file corruption which restricts them from accessing the backup files.

Suppose, you have been creating an incremental backup on an external hard drive. Recently you found that your computer has crashed and you reinstalled fresh operating system. After this updation, you tried to restore the backup files from external device to Windows. With Advanced Restore option, you find all the backup files. But when you tried to actually restore the files, it refused to do so with an error “The backup file could not be found. Check your hardware configuration or restore from a different backup (0x8100001A).” You check the permissions and find nothing causing this error. The backup restoration process finds the backup files when you click ‘Add Folders’ option, but it doesn’t restore your data.

When user faces situation like the above scenario, it becomes difficult for them to get back their data. Losing system data is a tough problem which can be avoided by restoring data from backup but losing BKF files adds extra difficulty towards the possibility of system restoration. If anyone follows manual methods for BKF repair he/she is not wrong. But if accuracy and successful recovery are concerned, one must choose commercial recovery tools. Kernel for BKF is such a third party software that repairs BKF file affected by any means of corruption. It repairs corrupt BKF archives from all versions of Windows operating system as well as BKF files created with Backup Exec by VERITAS Software, under Windows, Novell, and Macintosh.
