Don't know why others are complaining, but I have 2 servers I back up Maildirs from. One using rsync (my personal server) and the server here at work. Here we use Bacula to catch all our Maildirs. Theoretically, Maildir should protect you from inconsistencies. Worst case scenerio, a few emails here and there get backed up corrupted, but the rest of the Maildir will be fine. I've never heard of anyone having problems in practice, and we've done a few test restores of Maildirs here with perfect success. Our mail server is rather small: 2.8G of emails total, a little less than 70,000 mails. A full backup only takes 8 minutes, and incrementals usually take about 10 seconds. I guess our average mail size is about the same as yours. If Bacula scales linearly, you'd be looking at 8 hours for a full backup and 10 minutes for daily incrementals.
