Are you looking for redundancy or backups? Backups would protect you
from someone accidentally deleting things. Redundancy would protect you
if your hardware dies. Nightly backups are probably okay. Redundancy
sounds more like what you want here, IMHO.

If the stuff is in the database, it sounds like you need a slave
database set up, so you have a database set up in case the first one
fails. If you're doing all this with files, you might want to use a
fancy filesystem that does snapshots or something, maybe some kind of
distributed filesystem with Copy on Write or something. I'm not
completely certain what would do well. Something that could do snapshots
without consuming ridiculous amounts of space. I know ZFS can do it, but
that's not linuxy.
