ummmm, reading your requirements again, and cogitating..... and...
tar
a simple script that tars each file system appending it to the same tape
(assuming your backup fits on one tape)....
maybe something like...
mt -f /dev/nst0 rewind
for fs in / /var /usr /home /opt /data ...; do
tar clf /dev/nst0 $fs
done
mt -f /dev/nst0 offline
If you do your backups this way, its important to keep track of the
order you write the file systems to the tape, as the tape position is
the only way to distinguish them
I'd probably add some logging to that script, and basic error
trapping. the following mess is totally untested and probably full of
errors. caveat emptor.
#!/bin/bash
d=${date -I}
lf=/var/log/mybackups-$d.log
df=/var/log/mybackups-$d.detail.log
dt=${date +"%Y-%m-%d %H:%M:%S%z"}
echo "$dt ******* Starting Daily Backup **********" >>$lf
mt -f /dev/nst0 rewind
for fs in / /var /usr /home /opt /data ...; do
echo "$dt Starting Backup $fs" >>$lf
tar clvf /dev/nst0 $fs 2>>$lf 1>>$df
if [ $? != 0 ]; then
{
echo "$dt Error in tar $fs. backups aborted" >>$lf
mail -s "***DAILY BACKUP ERROR****" user@xxxxxxxxxxxx < $lf
exit 1
} fi
echo "$dt Completed Backup $fs" >>$lf
done
echo "$dt Ejecting Tape" >>$lf
mt -f /dev/nst0 offline
echo "$dt ******* Daily Backup Complete **********" >>$lf
