With mbox, the whole file will get backed up with every incremental backup if it is changed. If you have clients using IMAP or don't check their email often, you wind up with lots of big files. With spam and viruses arriving all the time, most mailboxes are getting changed daily. In my experience, incremental backups on mbox files do not save much space. For instance, I have about 12Gb worth of mailboxes, and an incremental backup using tar of only files modified within the last day, is usually about 11Gb. With maildir, I would imagine that an incremental backup would be much easier, as you'd only have to backup the last few messages that have arrived, though I haven't actually tried it. Comments from anyone who If you wanted to do efficient backups of mbox format messages, I suppose that rsync to another drive or system would probably be best.
