you might want to add borg, restic and - more recently - plakar to that list
Comment on Create a retention period for online backup storage

I think you need something like restic with a retention policy
restic.readthedocs.io/en/stable/060_forget.html#r…
–keep-{hourly,daily,weekly,monthly,yearly}
other solutions that implement similar policies are kopia and rustic

Restic is great, and the de-duplication between snapshots is amazingly good. Same content in different files (e.g. tar files of linux systems) take very little space like magic). Backrest is a nice web frontend for it.
Note that you should use some retention features of your provider to manage the risk of ransomware deleting your backups.
