    And here is one more reason for not using Snapshots with CCC. I looked where CCC was storing the snapshots on both my internal drive and on the destination external drive. Turns out they both point to /private/tmp and then folder inside that location. So, basically, the so called backup is stored on the drive being backed up. Which means when the drive fails, you lose all the snapshots. I'm turning it off in CCC. I think Bombich has made a fundamental error in making snapshot the default, particularly where it's being put.

    EDIT: I just turned off Snapshot on both source and target drives in CCC, then deleted the snapshots from CCC on both. I recovered 200 GB on the internal drive, 400GB on the external target drive. I wondered where my drive space went!

    Like I stated above Jake, I don't find Snapshots useful and have had them turned off ever since High Sierra and APFS of my internal SSD. And I do not like Time Machine making snapshots on APFS drives whether attached or not. It used to be that Time Machine would only make local snapshots if the external drive was not attached, but now, it makes them regardless. I have had to remove the snapshot after each Time Machine backup.

    I believe it only does that though with APFS formatted drives.

    Well, for TM I use TImeMachineEditor to run TM just twice a day, noon and midnight. So I have two snapshots, and only two at any time. I can live with that. I don't need hourly backups, nothing I do is that critical.
