We want to create a snapshot every, say 2-3 hours. Want I want to accomplish
is that I have a copy of a live-database.
If someone messes with the database I want to be able to replace the
messed-up one with the snapshot.
I also want an archive from the snaps so I can make a choise witch one to
put back in case of a messed-up database.

Can someone give sme some directions how to accomplish this?
