Hi,

I've just perform a mt rewind, then mt eof, then dd if=/etc/hosts of=/dev/rmt/0mn.
I try in sam to get list of files on device; but i have this error:
Getting list of files...
frecover(2105): did not find expected file marker
frecover(5409): unable to read volume header
frecover(5418): not an fbackup volume; unable to read volume header
frecover(2105): did not find expected file marker
frecover(5412): Do you wish to try to salvage this volume? (^[yY]/^[nN]) n
frecover(5411): Do you wish to try a different volume? (^[yY]/^[nN]) n

What's this trouble??

Regards

Jerome

Because you did the backup with 'dd' command and trying to read it with 'frecover'. frecover will only read the data if it was backed up with fbackup.

Hi

Your backup wasn't done with fbackup and couldn't read the volume header

Hi:

'frecover' simply doesn't see this tape as one that was created by 'fbackup' and hence cannot list the files that might have been on it.

You wrote to the tape with 'dd'.
