I'm just curious how other users are backing up maildirs using bacula. We're using cyrus as our mail server, so we've got about 162GB of data stored in 4.4 million files, or an average of 37K per message. Most other products I've tried (both commercial and open source) have not been too happy with this arrangement and end up requiring vast amounts of disk space and overhead to index this kind of mail spool.

Does anyone know if bacula is any better with this? If not, I'm thinking my best resort would be to have each user's mail spool gzipped before backing it up (we don't restore individual emails for users, so this kind of "resolution" is sufficient for us). Any ideas on a good way of doing this that won't require me to run an external crob job to do the zipping and require almost twice the disk space?

Any other insights would also be appreciated.

Thanks!
DC
