Read the manpage as it has lots of configuration potential. 2) Effectively a partial transaction history for the data where you can recover a file as it was, say, a week ago, for which dump and restore are your friends. There's also a tool in the ports which does something similar with rsync and separate trees named, I think, by date, which is great if you have lots of disk space. Or you can use snapshots, and again there is a tool in the ports whose name eludes me. cd /usr/ports make search name=rsync make search name=snapshot if you care.
