Backup and Restore Server suggestiosn (Linux)

I’ve seen a couple different answers on this one, but not quite what I’m looking for…

What directories should I be backing up on my UrBackup server, if I need to restore someday?

My client data is one disk, which is large storage array. (/media/urbackup/blah) not worried about that directory so much.

more like…/usr/share/urbackup/, anything else?

finally restore… is it as simple as installing a fresh copy of urbackup then mounting up the files/directories that were backed up?

thanks…

And the contents of /var/lib/urbackup.
