    So far been relying on 'just' TM backups (one on-site, one off-site), but intending to add CCC (or Superduper) cloning to it. Is there any reason not to have a TM backup and a CCC/Superduper clone on the same disk, albeit on two separate partitions (for instance), a large(r) one for TM and a small(er) one for the clone?

    It will technically work, but for backup strategy there would be a single point failure. If the the backup drive has a hardware failure, then both backups are lost on that drive.

    Sure, but I would have/use two sets/disks, with each a TM backup and a CCC-clone, on on-site, one off-site.

    I would not recommend keeping a cloned backup on the same physical drive that the TM backup is on.

    "Two backups -- two DRIVES".
    Things will work better that way.

    Thanks, good to know - should I get a dedicated ext SSD large enough for, say, 2 clones?
    PS: I sent you a PM with some additional questions.

    As long as you are doing this on two drives, there is really no technical reason you cannot do this. I see no problem.
