It will work. Look at man rsync and the --update option. If you use -u it will totally skip files that have a newer timestamp on the destination. If you don't use -u it will checksum the files and sync them if there's a difference (there will be in your case). So don't use -u in your rsync invocation. Also, why not try to be empirical?

I see you have started already excluding certain paths from your backup, with --exclude. One of the most useful rsync flags I have found is -F which simply allows you to place such lists of exclude file-patterns anywhere in your source tree.
