We’re really happy to announce that SuperDuper! uses snapshots on APFS boot volumes when copying. Copies should be much more reliable and less error prone, and (as usual) the whole process happens completely transparently to you, the user.
SuperDuper! is one of the best Mac apps out there. Does it’s job and does it well. Having a system cone is one-third of a correct 3-2-1 backup strategy. Have three backups, two local (one Time Machine, and one system clone), and one remote, like BackBlaze. Set this up and forget about it, and if (when) something happens, you’ve got three chances to get back your precious data.
