/dev/ad0s1b           none                swap     sw                 0            0
/dev/ad0s1a           /                       ufs         rw                 1            1
/dev/ad2s1d           /opt                  ufs        rw                  2            2

Hence, I should be able to sump / to /opt, then pull that file off the server, and then back up /opt to / and then pull that one down.

So, am I correct in the assumption that the command

/sbin/dump -0u -f /dev/nsa0 /usr/src

backs up /usr/src to /dev/nsa0, which I think is a tape drive?

Would the following command then do the job?

#dump -0u -h 0 -C 16 -L -f /opt/path/to/backupfile /

Then move /opt/path/to/backupfile away from that machine altogether and delete it. Then do a

#dump -0u -h 0 -C 16 -L -f /path/to/backupfile /opt

and remove that file from the server as well.

Thanks for your help.

No, you need -a if you back up to file

I woul use:

dump -0Lauf - /dev/slice | bzip2 > /backup/file.bz2
or
dump -0Lauf /backup/file /dev/slice

-L is if you backup slice on system, that you are running (meaning, you don't use live CD)
-u can be skipped



EDIT uh sorry, my mistake about that /sbin/dump -0u -f /dev/nsa0 /usr/src
Ignore this post

Edit: there was mistake in 2nd example
