Other than filesystem snapshots (if your underlying volume manager knows
about it) i don't see some very usefull/efficient backuping tools for
large mail spools. For example, i still rely only on raid mirrors :) which
leaves me cold in case of rm -rf / (or some such) but safe in case a disk
deceides to die.

Puting all the mail spools in the RDBMS just for the ease of backuping ...
i heard from the Oracle people that their DB is already 30% slower than
plain fs and cyrus is already very i/o demanding ... i don't want to
introduce another bottleneck. Altough, implementing all the little
databases cyrus has (mailboxes, duplicate deliveries, ...) in some RDBMS
might be usefull for large setups. Which still leaves the backuping
problem intact ...
