We keep hot masters (typical MySQL master-master-slave(s) setup) on standby. Bootstrapping one from scratch (like if we need to stand up a new replica)? We restore a disk image on GCP from point in time snapshots, then let it catch up on replication. So it'll depend on how far behind it is when it comes online. TLDR: a few hours in the worst case. ~Zero downtime in practice. |
