Re: database backup

Hey - you *could* consider logging your commands elsewhere and use *that*
for incrementals. It wouldn't have all the nice features of transactions
so it might take some manual effor to recover but you may not need
anything beyond a naive implementation.

So alter your application to save all SQL that can modify the database and
use that to augment your normal scheduled backups.
