Sure I can ask John to make a quotation for a backup script (remember... he's working for a foreign IT-company). But bare in mind John has no Moodle knowledge whatsoever.
The server is being backup-ed, so no worries there. It's just that a server backup takes a long time to restore as well when you have a big Moodle installation.
What I'm dealing with is outside the red area and I do understand that this is not Moodle's focus.
On many occasions I'm just running into problems only sites with 5000+ users seem to have. This is just one of them. I have never seen automated backup working on sites outside the red area.
I love Moodle, don't get me wrong, Moodle seems to be perfect for small(er) schools... it's just that I run in many limitations where things are just a little more complicated that the school-server.
