[KLUG Members] Backup

[Jeremy Leonard]

I recently got a DAT autoloader. It holds 6 tapes.
I've only ever used a single tape drive in Linux.
I'm trying to figure out how to use the autoloader so I can actually
backup all of my server at once with out changing tapes.
Below is the backup script I've been working with.

The backup starts fine and fills the first tape.
It removes the first tape and loads the second tape then fails.
It says the load operation failed. But the tape is loaded and if I
manually start a backup it writes to the tape just fine.

_________________________SCRIPT START__________________
if (tar -cvf /dev/st0 -X /root/bin/exclude -F 'mtx next' --totals -V
"Daily Backup" -S -M / ) ; then
echo "The backup was successfull!"
else
echo "The backup failed. Please check the log"
fi

if (mtx unload); then
echo "Successfully ejected the tape"
else
echo "An error occured!"
fi
