Mailboxes are in Maildir format. Any good backup tips? Had success with version control?

     Some may agree with me, some may disagree. But for my Maildir 
backups, i usually exclude the files "dovecot.index*".

     On the most common situations, you'll need to restore just one or 
other mailbox, so rebuilding those indexes wont kill the server. And by 
excluding these, i could save 10-15% of backup space on some cases with 
virtually no disadvantage.

     And on a worst case scenario, where i would need to restore the 
whole server and mailboxes, things will already be screwed, so knowing 
that dovecot would be harder on I/O for rebuilding the indexes will be 
just another problem :)
