Actually, newer versions of ZODB have a script called repozo.py which
makes incremental backups feasible.  It knows a lot about FileStorage's
formats.  Also note that there are alternative storage implementations
such as BerkeleyDB-based storage (slow, but presumably more reliable)
and the 3rd party DirectoryStorage.

We'll talk about databases in another thread.  I have my own biases, but
I'm too tired now to get into it.
