Steps to restore corrupted Exchange BKF File

Being an Exchange user for a while you might have faced the worst situation when you were tried to mount server data with the help of BKF file (Backup File) and Exchange showed some exceptional errors. This is the most hectic time for the Exchange administrator.

Exchange Server holds the crucial user’s data thus no organization either big or small can bear such loss. Exchange creates backup file of all the data like emails, contacts, notes, attachments and all. These files are stored with the .bkf extension. Exchange database keeps all the below stated files:

  • EDB (Exchange Database Files (.edb))
  • STM (Streaming Media Files (.stm))
  • LOG (Transaction Logs (.log))

With the “NTBackup” command provided by Microsoft user can easily take the backup. This command is the default utility with Windows NT but for other versions it can be downloaded easily. Though NTBackup performs well but still this BKF file gets corrupted and leads to a wobbly situation for the admin.  There are a number of reasons which can corrupt the Exchange BKF file
