This just compares each file in /home/<usersname> with its corresponding file in /backup/<username> and copies any that are new or have changed, resetting the archive bit for each file.
Not to nitpick, but actually, rsync is smarter than that - it only copies the diff between the parts that have changed.
If your data to be backed up consists of 2 10GB files, and you make a slight change (say 5 few kbytes) to each, rsync wouldn't copy 20 GB, but rather just the changed 10 kb, plus a bit of overhead.

You're right - I remember reading that but I'd forgotten it.
