I initially thought it was weird they had to run several "processes" in case 1 failed. But running out of space or something correctable is actually something likely to happen. Is this standard? It's quite smart.
Anyway, assuming they get the data back, I think they've done pretty good - 0 data loss and a days downtime isn't bad given this is a true disaster.
It would be nice if they'd let us know how the db got deleted, and what they suggest to mitigate in a blog after.
