Alternatively you can use dsync to 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 calling doveadm user * and feeding its output to something like

while read user; do
dest="/var/backup/dovecot/$user"; mkdir -p "$dest" && chown vmail:vmail "$dest"
&& chmod 0755 "$dest" dsync -u "$user" backup "maildir:$dest"
done

Note 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 doveadm of my Dovecot 2.2 (Debian 8.0 Jessie) does not support the "backup" subcommand. Is it a past-2.2 addition?
