• Time Machine Question

    From gtr@xxx@yyy.zzz to comp.sys.mac.system on Friday, December 18, 2020 11:31:05

    I have TM on a 4T drive. It has used 3.7T of that drive. I moved from
    Mojave to Catalina 4 weeks ago and it has been "Preparing backup..."
    ever since.

    Yesterday, I ran First Aid on the TM drive and it found many link
    errors and reported successful correction. It has now spent 24 hours "Preparing backup..." One guess why it takes this long is that it
    creating a new inventory file for comparison to my internal drive for comparisons and identifying which file to backup; the drive is huge so
    it is taking its sweet time.

    ** My question is this: Can I "slim" the TM repository? It is 3.7T and
    goes back to Auguest 2018. I don't need all that. Can I simply go to
    the oldest folders and delete half of them? If not, is there an
    appropriate way to lose the oldest full year of backups?

    Though I don't completely trust the "whatever you find in Google"
    because I don't know whether issues and solutions have changed since it
    was posted, it seems that this is safe to do. So I'll give it a shot.

    A much better way is to use the tmutil command-line tool:

    # tmutil listbackups

    /Volumes/Time Machine Backups/Backups.backupdb/services/2020-04-24-022255 /Volumes/Time Machine Backups/Backups.backupdb/services/2020-05-01-103150
    ...
    /Volumes/Time Machine Backups/Backups.backupdb/services/2020-12-18-143907 /Volumes/Time Machine Backups/Backups.backupdb/services/2020-12-18-164020

    # tmutil delete /Volumes/Time\ Machine\ Backups/Backups.backupdb/services/2020-04-24-022255

    tmutil: delete requires root privileges.

    # sudo tmutil delete /Volumes/Time\ Machine\ Backups/Backups.backupdb/services/2020-04-24-022255

    Deleting: /Volumes/Time Machine Backups/Backups.backupdb/services/2020-04-24-022255

    Total deleted: 1.2G

    Duly stashed. I assume this keeps me from having to "empty the trash".
    After deleting a score months, I find I must also empty the trash.
    It's been emptying all day and is currently beyond 2,000,000 and gives
    every indication of deleting files through the night.

    What maks it a better way? Does the "tmutil delete" command preclude
    the trash emptying? That would have been handy.

    An other benefits to this method over deleting via the finder?

    It's now at 3 million and looks to be doing this task for the rest of
    the weekend. Oh well. The wife reminds me I should have taken out the
    trash sooner, rather than every two and a half years...
