    The very long-shot chance is to export the pool (after backing it recent changes), use zdb to see what its current TXG number is, and re-import the pool with an earlier TXG number using -T.  You'll lose files or changes created after the old TXG, AND if it's been a long enough time or a full enough pool, you won't get back to that TXG.

    It's an extraordinary measure, one I wouldn't take unless I was truly desperate.

We do nightly backups, but this would be a file that was deleted before the coming daily backup.  Does anyone know if there is a service that can do file recoveries from ZFS?
