I assume also then that files deleted off of the server will not be deleted off the backup since the default rsync options don't include any of the delete options.

Unfortunately, I have some servers that have a constant creation and deletion of files. This might make it difficult to tell which files would actually need to be restored and which are no longer needed. I'll have to investigate this a little further.
