Alternatively you can use
dsyncto perform backup with a native Dovecot tool. It's able to sync mailboxes of any Dovecot user -- including synchronizing a mailbox to an empty (yet) spool. You'll need to do a bit of shell scripting which would spin around callingdoveadm user *and feeding its output to something likewhile read user; do
dest="/var/backup/dovecot/$user"; mkdir -p "$dest" && chown vmail:vmail "$dest"
&& chmod 0755 "$dest" dsync -u "$user" backup "maildir:$dest"
doneNote that you will only need this if you don't want to shut down Dovecot to copy its mail spool out.
You can also use doveadm backup -A maildir:%u/
Looks like
doveadmof my Dovecot 2.2 (Debian 8.0 Jessie) does not support the "backup" subcommand. Is it a past-2.2 addition?We aren't past 2.2 yet. But it should work with dsync -A backup as well I guess.
Oh, that's a documentation problem: the manual page doveadm(1) does not mention the word "backup" at all while running the command actually tells it's supported:
$ doveadm backup -A doveadm backup [-u <user>|-A] [-S <socket_path>] [-dfR] [-l <secs>] [-r <rawlog path>] [-m <mailbox>] [-n <namespace> | -N] [-x <exclude>] [-s <state>] <dest>
Good to know, thanks!
