Do we just need to snapshot the LVM volume that holds all the Maildir boxes, or is there some additional commands that we should run before doing the LVM snapshot?
What's the best way to do long-term backups of the Maildir format these
days? Traditionally we've just done a rdiff-backup or pointed Bacula at
the Maildir. Both give us the option to reset a particular mailbox back
to a previous day (any day within the last N months).
