This was an interesting read! I hope they do a follow up article on how they automatically manage the rest of their recovery process.

- pizza234 7y agoIf with "recovery", you intend recovering that file, it's not possible, since all the copies available in the mirror are corrupted. In this case, the recovery (repair) of the system (that is, to bring it to a clean state) simply consists in deleting the file (see https://docs.oracle.com/cd/E26505_01/html/E37384/gbbbc.html#gbctx https://docs.oracle.com/cd/E26505_01/html/E37384/gbbbc.html#...). If there was an intact copy of the file available in the mirror, then one doesn't need to do anything, as ZFS is self healing: https://blogs.oracle.com/timc/demonstrating-zfs-self-healing https://blogs.oracle.com/timc/demonstrating-zfs-self-healing.
- kchamplewski 7y agoPresumably they're referring to Datto's recovery process (i.e. recovering automatically from secondary or tertiary backups), as opposed to just the ZFS mirror.
