BackupPC should cope with this. It uses rsync over SSH, so only needs to transfer new/changed files, and will restart where it left off if the connection fails (this happens to me sometimes when I switch off my laptop while it is backing up and the backup just restarts the next morning). It is also space-efficient when backing up multiple machines, it uses hard links to store only one copy of each file, no matter how many machines have the same file. The lack of network access from the clients to the server would mean you couldn't access the web interface from the client you wished to restore to, but you could do that on the backup server if necessary. -- Neil Bothwick The mechanic said I had blown a seal.
