Re: Backing up and restoring maildir folders

[Leonardo Rodrigues]

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.

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

Backing up and restoring maildir folders

[Timothy D Legg]

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,
