It seems that for the most part, folks seem to rely on replication and node replacement to recover from failures, and perhaps this is a testament for how well this works, but as long as we're hauling out aphorisms, "RAID is not a backup" seems to (partially) apply here too. I'd love to hear more about how the community does restores, too. This isn't complaining about shoddy tooling: this is trying to understand--and hopefully, in time, improve--the status quo re: disaster recovery. E.g., given that tableslurp operates on a single table at a time, do people normally just restore single tables? Is that used when there's filesystem or disk corruption? Bugs? Other issues? Looking forward to learning more. Thanks, Maciek
