Super interesting post. Would love to read more detail about their backup and restore infrastructure.
If Tom and/or Shlomi are reading this: you mention taking multiple logical backups per day. What benefit does this bring versus just having one per day and doing a point-in-time restore using binlogs? Is this just a tradeoff between time taken for a restore and storage you're willing to dedicate to backups?
