With rsync, the time required to do a backup depends as much on the number of files as the total size of the data. For example, backing up an email server with 20GB in 2 million files will take much longer than backing up 10 2GB isos.(*)
So "I backed up X GB in Y minutes" is meaningless without knowing more about the characteristics of the data. (*) And if you're backing up more than a few hundred thousand files, watch your memory usage on server and client. If either begins swapping your performance will suffer greatly.
