If the data is important, it has always been advised to take its backup so that if by chance you lost the data, still you can manage to restore that back. But, without any backup copy, there are chances that you may not get back 100% data. As Microsoft Exchange Server stores all the business critical mail transactions of your entire organization, it is important to keep backup of the mailboxes, using NTBackup utility.
These backup files of your Microsoft Exchange Server are stored in the form of a BKF file. Unfortunately, there are situations when these BKF files get corrupt and all the precious mail items become completely inaccessible. Such situations can be extremely crucial, but you can recover data from such situations using any Exchange server BKF recovery utility.
These days, not only big organizations, but also entrepreneurs have started using Microsoft Exchange Server. Indeed, Exchange Server has helped to keep their email transactions, without being dependent on mail servers, like Gmail, Rediffmail, and Yahoo etc. Thus, the Exchange Server stores all the data of the corresponding mail accounts configured on it.
As the mailboxes contain all important mail conversations, including emails, contacts, calendar entries, notes, tasks etc, losing them can lead to huge business loss. This is the reason; it is everywhere advised to take backups of the Exchange mailbox. Microsoft has provided an inbuilt utility, NTBackup that is meant to take the backup of the Exchange Server mailboxes, containing the .EDB, .STM and .Log files.
But, there are times, when these Exchange backup files (.BKF) get corrupt and all the data in them becomes inaccessible. Some of the common reasons behind the corruption of the BKF files are as below:
- Interrupted Backup: The interruption of the backup process results in the corruption of BKF file
- Virus Infection: Infection due to Virus or malware attack makes the BKF file inaccessible
- Corrupt or Missing Header: If the file header of MS Exchange gets corrupt by any means, it makes the file completely damaged and inaccessible.
Like the above listed ones, there are a number of such reasons for which the Exchange BKF file can get corrupt and shatter your hope of restoring data in case of Exchange problems. However, there are many advanced data recovery utility available in the market, which can repair the damaged BKF file and recover all your data back.
