How to read contents of a backup tape.Pls Help

Hi all,

i am trying to read the contents of a backup tape with the below command:
frecover -Norv -f/dev/rmt/0m 2>&1

and i get this response:

frecover (2105) did not find expected file marker
frecover (5419) checksum on volume header is incorrect
frecover (5420) not an fbackup file volume; magic value is incorrect
frecover (2105) did not find expected file marker
frecover (5412) do you wish to try salvage this volume?

Could you pls tell me if the command i type is correct? and what command should i give in order to check the contents? What i understand from the error message i get is that maybe the backup was not made with the fbackup command. Is that the case? And what i can to solve this problem?

It sounds like it is either corrupt or not created by fbackup (I am assuming this is HP-UX).

You could try dd if=/dev/rmt/0m bs=1024 count=1 to see what the start of the tape has to say for itself.
