My point is that even with o(100) files/copies which assuming you are
backing up multiple versions means you have far fewer distinct files
-- you may be better off just writing a script...

BackupPC is really targeted at backing up large trees of thousands of
files. If you just have a 100 large databases, why not just use a cron
script that copies each one and appends a datestamp or stores it in a
different folder. It will probably be much faster too...
