I have searched these forums for backing up the server itself ((linux)), I would like to have a server onsite backing up to a remote. I found this thread:
I just started using Urbackup yesterday and the first thing I did while setting it up was to setup a remote UrBackup server, install a client on my local backup server, select the entire master directory as my main folder and I am not doing image backup. I would suggest you use VPN to secure the connection.
