I have a file server on location and a backup server. Right now I'm using Robocopy to make nightly backups of the 8TB of data of which 7GB changes daily. We are afraid that a single fire or lightning could destroy all our data so we have decided we require an off site server with an upto date version of the data, which could be used if the primary is off-line.
Now I keep reading about dfs-r but one thing escapes me and I cannot find confirmation anywhere.
How is the connection between primary onsite and secondary offsite made ? Is a VPN connection between the 2 sites required or does dsf-r itself make a connection between the sites which are seperated by the internet ? Arjan
