What is a BKF file?
BKF is a kind of backup file. It uses the Microsoft Tape Format (MTF). And it uses BKF as its file extension. Usually, BKF files are created by the built-in backup utility in Windows OS, such as Windows NTBackup. Some other apps, such as BackupAssist, Veritas Backup Exec, Symantec Veritas Backup Exec, and Veeam Backup & Replication also use such a file format to store the backup data.
Why a BKF backup file will get corrupt?
There are many reasons that will corrupt a BKF file, such as hard disk failure, software defects, viruses, power off during the backup process, unplugging an external hard disk during data transfer, etc. Normally you will notice file corruptions when you extract data from BKF files. Our BKF repair tool supports to recover data for all the BKF file corruption issues. This will help to reduce data losses.
Which kinds of backup files can be repaired?
Our BKF file recovery software supports to repair the following kinds of backup files:
- BKF files created by Windows backup utility or Windows NTBackup.
- BKF files created by all versions of BackupAssist, Veritas Backup Exec, Symantec Veritas Backup Exec, Veeam Backup & Replication, and all other utilities compatible with the BKF file format.
Which versions of Windows operating systems are supported?
Currently, our BKF recovery software supports all versions of Windows OS, including Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows 10, and Windows Server 2003/2008/2012/2016/2019. Both 32bit and 64bit are supported.
Do you support to repair corrupt Zip files?
Our BKF recovery tool does not support to do so. You can use DataNumen Zip Repair to repair corrupt or damaged Zip files.
What is the difference between the demo version and the full version?
The demo version is a free version. It will report the list of the data items in the corrupt BKF backup file, including the file name, file extension, file size, volume, etc., but will not output them. You need to purchase the full version to get these files.
The demo version and the full version use the same recovery engine. So what you see from the demo version is what you will get from the full version.
If you want to recover a file, but cannot find it in the list of recoverable files generated by the demo version, then the file is beyond recovery and you cannot recover it via the full version, either.
Where can I download the free demo version?
You can download the free version by:
- Visit https://www.datanumen.com/bkf-repair/
- Click the “Free Download” button to download the free version of our BKF repair tool.
What are the requirements to install your BKF data recovery tool?
Below are the requirements for our BKF file recovery software:
- Intel Pentium compatible processors.
- Operating system: Windows 95/98/ME/NT/2000/XP/Vista/7/8/8.1/10 and Windows Server 2003/2008/2012/2016/2019.
- At least 10MB free disk spaces.
Do you support Windows 10 and 11?
Yes, we have tested our backup recovery tool on both Windows 10 and 11 and do not find any problems. However, the current official release only lists Windows 10 in the supported operating systems. We will list Windows 11 in the next release.
How long will it take to recover a BKF file?
The following factors will affect the time:
- BKF file size.
- The total count of items in the backup BKF file.
- If the items in the backup are compressed, then it will take more time to recover them.
- Hardware and software configuration of your computer system.
Moreover, our BKF recovery software has two scanning modes. You can change the following options to increase/decrease the time consumed in the scanning process:
- Click the Options tab.
- If the Fast scan and recovery option is checked, then our BKF file recovery tool will perform a faster scan and recovery on the corrupt BKF file. This option normally works for minor BKF file corruption issues. However, after the recovery, if some files are not recovered, then you can adjust the scanning mode by unchecking this option, and restart a more thorough scan and recovery on the source file.
Are there any special requirements for the output directory?
Yes, to make sure our tool can extract BKF file successfully, below are some requirements:
1. Enough free disk spaces for recovered data
- If the items in the BKF file are NOT compressed, then the free disk spaces should >= (original BKF file size) * 1.1.
- If the items in the BKF file are compressed, then the free disk spaces should >= (original BKF file size) * 5.
2. Do not use a network drive
Do not set the desired location of the recovered data to a network drive. Network drive will slow down the recovery process and cause data corruption.
Do you offer a search option so that I can search specific files in the BKF file?
Sorry but currently our BKF repair tool does not offer such an option. We have added this to our to-do list and will implement it in the future. You can subscribe to our newsletter to get notifications when we release new versions.
Is there any size limitation on the BKF file that can be recovered?
Our BKF recovery tool can repair corrupt BKF files as large as 16777216 TB. In the real world, you will not encounter such a large file. So, actually, there are no size limitations on the source corrupt BKF files.
Will you output a fixed BKF file, or extract data inside it?
Our file repair tool will extract recovered BKF file data so that you can use them directly. It will extract all the data items, including datasets, volumes, folders, and files.
Do you have screenshots of your tool?

- Install our BKF recovery tool on the PC/Windows system.

Do your BKF recovery tool support to extract only selected data items in the corrupt BKF file?
Sorry, but currently our BKF repair tool does not support such a feature.
Will you recover all data in the BKF file?
Our backup recovery tool will try its best to get all recoverable data for you. However, if your BKF file is badly corrupt, then some data may beyond recovery. To reduce data loss, we have the following recommendations:
- Back up your data regularly.
- Check your backup files regularly. Some backup utilities can verify the integrity of the backup data.
- Store redundant backup files in different locations, and make sure there is at least 100 km between these locations. Thus if something happens in one location, such as an earthquake, there will still be other copies available in other locations. We recommend you to store one set of backups in your office, and a copy set in online Cloud storage, such as Google Drive.
Your BKF file recovery software fails to recover my BKF file. What to do next?
Please contact our support team. We will help to analyze your problem and backup file manually. We will try our best to reduce data loss in your case.
