We've got a Gerrit service running on a Ubuntu server with a few Git repositories over there.
Everything that we do needs to be backed up somewhere on a server located in our network.
We can't store the repositories over there and only use that server as the connection to it is fairly slow.
I have done some research and I found a couple of ways of doing this, but still I'm not exactly sure if these are up to date and how exactly I'm supposed to do this.
Sorry but I really need some help.
You might be interesed in Gerrit Replication plugin and its docs.
