Hi Corine,
I recommend you consider rsync and rclone as completely different tools.
They have some common functionality like synchronizing files to a remote server, but once you dig a bit deeper in the possibilities and limitations, they are quite different.
You may be able to achieve your goal by using rclone sync with --backup-dir and associated flags/options.
You may also be able to achieve you goal by using rsync to a (remote) folder exposed by rclone mount.
Finally, there are services like rsync.net that together with rclone may fit your needs. HowToGuide.
I suggest you play a bit with the above possibilities to see which (if any) of them fit your needs.
