Backup Exec is used to back up servers, applications, and workstations across the network. But somehow if in future backup exec file got corrupt then it will be difficult to access again. so, to avoid corruption or damage I suggest you use the Backup Exec BKF Repair Pro Tool which allows you to recover multiple BKF files in one shot with the help of two different scanning modes, you can select Standard mode or Advanced mode as per the damage.
It also supports your SQL database recovery and extraction as well.
