At the risk of repeating myself, I would just like to point out that even
putting the databases in their own dbspaces is not a solution to your problem,
as described here. If you restore just a single dbspace, you MUST go through
logical recovery. This means that when someone "accidentally" deletes his
database, the logical recovery *replays* the deletion, and at the end of the
recovery, you're back where you started, i.e. your database is still deleted.
What individual dbspace backup buys you is reduced time to restore, and ability
to keep using the other dbspaces while one is being recovered.
