how to append a new backup without overwriting existing ?
# tar -czf /dev/st0 /home
and check/list via
# tar -tzf /dev/st0
ok, but when I try to create another backup on tape, via
# tar -czf /dev/st0 /data
then the previous backup(/home) gone.
# tar -tvf /dev/st0
only shows /data, and not /home.
and I want both /home and /data backup on tape.
please help
Regards

Re: how to append a new backup without overwriting existing ?
This is very dangerous (error prone) and you don't want to do this. If you successfully put it on your tape, you'll need to remember how to get it off. If you have N backups, then how will you remember what's where?
>I want both /home and /data backup on tape.
You can put both there in the same pass:
tar -czf /dev/st0 /home /data

Unless GNU tar -r is different than HP-UX, you can't use -r with tapes.
