The --backup option means that files on the destination system which are about to be lost (because they were either deleted or modified on the source system) are instead saved (with a new name, or under a different directory if you also use the --backup-dir). I use this option as a sort of "incremental" backup - I have a useful snapshot of the last full backup, but also copies of all files as they were at each intermediate change, in case I want to recover a file that I deleted or modified a month ago, for example. When you do use --backup, massive deletion is not a terrible problem, because all the deleted files are saved in the destination filesystem anyway.
