Hi,
I currently have 3 backupservers: All of my devices (servers, computers and my mobile) put their important files on server1. Then every night server1 syncs (over rsync) all files with server2. Futhermore, I manually sync server1 with server3 over rsync every few days. I think my files are safe now, but when a disk on server1 corrupts and destroys a few files, these destroyed files will be synced with server2 and I might not notice that as the servers sync automatically. I wonder if there is a better way of how to use these 3 servers as backupservers. The files on this servers are all of my private files (pictures, my music, my documents etc.) so they are really important to me.
Thank you!
