frecover message

[Suni Raj]

Hi,

I am trying to restore few files from a tape using frecover. I ran the command frecover -V /tmp/header -f /dev/rmt/0m to know the volume label. But I am getting a message as:

frecover(2105): did not find expected file marker
frecover(5419): checksum on volume header is incorrect.
frecover(5420): not an fbackup volume; magic value is incorrect
frecover(5412): Do you wish to try to salvage this volume? (^[yY]/^[nN]) frecover(4302): frecover interrupted, continue? (^[yY]/^[nN])

I understand it says it is not a fbackup tape. But I confirmed with Tape team that it is the same tape. Is there any other chance to see the files are there in the tape? Can anyone help me in this?

frecover -N -f /dev/rmt/0m
Does it list anything.

tar -tvf /dev/rmt/0m

you need to identify what tape it is.

Somebody has overwritten the tape with sokmething else, perhaps tar or cpio. frecover is just verifying that the volume header is present and the length and content of the first few records are correct. The records on the tape aren't fbackup records, thus the message. That's why *all* backups must be scripted with an immediate eject after finishing the job (mt offline).
