Thanks Soxfan and Phoenix for your replies. We are using the network edition.
The Timout policy had totally slipped by when I was searching in the Admin console... Does exactly what I was looking for
I found this documentation in the AdminGuide for the zmbackup command

I can't see any command line parameters for how to archive emails? Using Thunderbird will take to much labor work and I'm looking for a way that I can use regularly without to much hassle.
Exchange has a tool called ExMerge that does this and i've used a lot. There must be some simple way to do this in Zimbra as well.
