I haven't used rclone, but `rsync --link-dest` lets you create an incremental snapshot using hard links so that you don't have duplicate files between snapshots. Wrap it in a shell script, and you have something surprisingly useful.
rsync --link-dest can't do content deduplication, can't upload to the cloud and it's much more inconvenient to use for doing and managing backups than Duplicity, Duplicacy or Duplicati.
I won't link to my wrapper script because I don't want my HN account linked to my github/real name but this guy's work is what I based mine on: https://blog.interlinked.org/tutorials/rsync_time_machine.ht...
