I used to do something similarly complex to the OP with ssh and --link-dest to make it share inodes so I could easily keep N days of backups with file level deduplication [1]. Then I moved to Borg and haven't looked back. It does the same end goal in a better way, is way faster, and easier to work with overall [2].
