subject: Symptoms And Recovery Options For A Corrupted Bkf File [print this page] Windows NTBackup is a backup utility by Microsoft that uses its own file format called BKF to hold all the user-chosen files and folders. Like all other files, a BKF file is also susceptible to corruption and can render your important data inaccessible, critically when it has already been deleted from the original storage media. Corruption in BKF file can be a result of media malfunction, third-party software interaction, virus attack, low resources, file system errors, and other similar reasons. A damaged BKF file loses the ability to get restored. This article explains some of the most frequently occurring symptoms that can be seen with a corrupted BKF file and later mentions the available BKF Repair options to extract the file data.
As mentioned, a corrupted BKF file becomes completely inaccessible. Since this behavior can root from other causes also, you sometimes need to know the specific symptoms of BKF file corruption.
Symptoms
When you try to restore the BKF file using NTBackup Restore feature, the tool might go very slow, while consuming more than expected CPU resources. Alternatively, you can observe that the system prompts you that it cannot recognize the BKF file. In rare cases, it might succeed in detecting the BKF file as valid, but not the included files. On each attempt of opening the included files, it may give you errors such as: 'Access Denied'.
As per different users' reports, a corrupted BKF file usually gives one or similar type of the below mentioned error message, when you attempt to restore it:
The backup file contains unrecognized data and cannot be used.
Or
The backup file is unusable.
Or
An inconsistency was encountered in the requested backup file.
If you encounter any of these situations, see the below 'Recovery Options' section to repair the file.
Recovery Options
Microsoft doesn't provide any utility to Repair BKF File. Thus, the only options are either to restore the data from another copy of data or use a BKF Repair software. Third-party tools for repairing corrupted BKF files can scan and repair the file without affecting its integrity.
