This way you can back up your entire server, not only the mailboxes.
Instead of openvpn, I use openssh. Use compression in the ssh tunnel,
not the rsync connection, as rsync compression tends to be buggy and
interrupts the download. I run sshd on a non-standard port to keep my
logs relatively free of script kiddy noise from people looking for an
ssh connection to crack. Run fail2ban to lock out the remaining script
kiddies. Use a client certificate to log in with ssh unprompted,
making it easy to download in a cron job.
There's more than one way to skin a cat :) Moving the ssh port and
adding fail2ban in the mix is another option. Personally tend to use VPN
tunnels for dynamic IP clients for various reasons, such as being able
to lock clients out by revoking keys.
