Literally any situation where the undesired change to be recovered from happened before this last and single copy was taken.

Pretty much, yes. But at backup time you don't care about that. And the recommendations against the dump format for a backup is the fact that the dump/load cycle is much slower, emphasis on the load part.

To verify a successful backup, yes. Again, you don't need to care about how long the backup takes. Only about it's consistency and the time to restore in a restore event.

Good luck,
Andreas
