I've tried this. The first link given by you can be opened but didn't work at all, but the other one is not even getting opened. I really didn't understand. May you please go in little depth, since technically I'm not that good? Thanks. No, my Symantec backup exec is working nicely. I have some other BKF files which are saved inside my Pendrive. They can be easily opened as well restored by using the same backup exec. File corruption seems to be the possible cause.

I've already tried to catalogue my files, but still no luck. Any help?
