You might have faced the situation when you know that your system is at risk and can crash any time we always think of backing up the data. Most of us use the NT back utility for the backing up the data in windows operating system like Windows Server, 2003, XP, and 2000. The back up is created with a file extension .bkf. But we are talking about the scenario where the bkf files get corrupt. You might be thinking then whats the benefit of backing up the data. But this can happen due to human error, virus infection, power surges, incomplete data back up process and missing catalog files. What we need to do is to take the adequate corrective steps to recover the data from the situation.
Lets take a scenario to make it a bit more clear. So you took concurrent back ups of data on several location at a go. Now you want to restore the data but you are not able to do so. The error you find is that you are not able to locate the catalog files in the restore tab. The catalog file are tose which let the NT back up to restore the file from the bkf file. We have still not taken into consideration the the back up is not possible without any error message. And when the error message displays it can be anyone from the following errors.
1.Backup file contains data that is not recognized and cannot be used.
2.Unusable backup file. You must erase it, or choose another file.
3.Inconsistency encountered for the requested media
The reason beyond is that the back up file is corrupt due to any of the reasons mentioned above. One of the major reason can be missing catalog files of your backup data.
The catalog file gets corrupt when you simultaneously create on backup after the other, The catalog file share use identical time stamp. In this case as you were able see the restore tab and after that it displayed the error message its because, the backups were sometimes not displayed in the list and some time s it gets displayed. In such case only BKF recovery tool can help you recover data.
