And what format is this information in?
If it had been tar'ed to the tape you would say something like:
tar -tv -f /dev/sa0
to list the contents and
tar -xv -f /dev/sa0
to extract.
But if it had been written with, say, dd then something like
dd if=/dev/sa0 of=/your/output/file
might do to read it, but you'd probably want to set a blocksize with
e.g. bs=32k or bs=64k but that depends on how the tape was written.
So how was the tape written?
