What I am interested in, though, is, how to backup the whole git server with all repos - daily, onto a server in a datacenter. E.g. should new repos be added, they should automatically be backuped as well.
Because of NAT and dynamic IP addresses, the datacenter server cannot access the local server, so the backup would have to be initiated by our git server.
Before I now go for a bash script iterating over all repos, I'd like to know whether there is a solution built into git!?
