Yep, what program did you use to make the backup? For me I have a cron job
that runs nightly and uses tar to back things up. The command I use is...
tar --totals --label="System Backup For `date -d yesterday +%m-%d-%Y`"
-cvf /dev/tape /
Then when I want to restore something off the tape (say my home
directory), I'd do the following...
tar xvMf /dev/nst0 home/zoid
This will restore my home directory to whatever directory I am currently
in. Maybe give that a shot and see how it works.
