Backing up and restoring maildir folders
Hello,
I am migrating to a different distribution of Linux that involves changing to an earlier version of dovecot (2.2.22 to 2.2.13). As part of this process, I will be copying several maildirs to the new machine. One of these has a number of files and directories that resemble this one example:
cur/ dovecot.index dovecot.index.cache dovecot.index.log dovecot.mailbox.log dovecot-uidlist dovecot-uidvalidity dovecot-uidvalidity.59206030 .Drafts/ new/ .Sent/ subscriptions tmp/ .Trash/
Is it good enough to simply stop dovecot and tar this folder, and others like it, and copy them back to a similar location on the new installation? I haven't yet seen anything that resembles an official or standardized backup/recovery method for dovecot.
With thanks and appreciation,
Tim Legg
Backing up maildir is easy, just backup (and restore) the whole thing and, usually, that's as simple as that.
However, for saving some backup space if that's a matter, i would exclude only the 'dovecot.index.cache*' files, as these can be rebuilt (some performance hit after the restore, of course) but, in some servers, that makes almost a 10% difference to me.
Besides the cache files, you really should backup everything inside the maildir folders.
