Multi-machine backup solutions

"A solution that I've used successfully in the past is BackupPC. It runs on a single server and periodically pulls backups over rsync or ssh or samba from all the other machines. It has many useful features, too many to describe here.

BackupPC is free and open source software."

"This won't handle backup for your Linux machines but for the Windows machines on your network, I highly recommend Windows Home Server. The license cost is managable ($100) and it'll handle up to 10 machines, which is sufficient for home use.

An option for the linux hosts would be to rsync criticial data to a fileshare on one of the windows machines and make sure that that gets backed up regularly via the WHS."

"Syncplicity allow you to use ""as many computers as you like"" with the standard subscription. If you don't want to take advantage of their synchronization functionality, you should be able to turn that off, and just backup all your machines using the same account/license on each.

Unfortunately I don't think they have a Linux client at present."
