Time Machine

One of new features, aimed at ensuring people improve their backup habits and enabling intuitive restore.

Freeing up local snapshots {#freeing-up-local-snapshots}

If you find that the hourly snapshotting feature (which uses your internal storage) is taking up too much storage for your liking, you can toggle it off and on again to free up space:

sudo tmutil disablelocal
# Wait for it to be freed up automatically
sudo tmutil enablelocal

Or, in Big Sur, you can just

sudo tmutil deletelocalsnapshots /
