Simple backup of maildir folder

Hi,

I want to do a simple backup of my maildir. I read here that maildirlock is not to count on in the future and the recommended option was to use doveadm backup. However, it seems that this requires to setup another dovecot server.

My questions are:

• How much to I need to configure this new server? Do I need to setup user by user, or even install postfix (that's where my users are configured) to get it all backed up? I tried to install dovecot and running doveadm backup, but it complains the users are not there.
• What's the simplest way to configure dovecot without mirrowing my server so that this can work?

Best,

Francis
