I just pulled a GitLab on a production database. Total downtime: 15 minutes Total data loss: one hashed password field. Our backups work.

having a single db instance run as a delayed slave (i run it 12 hours behind to cover if i fall asleep) is so comforting. haven't had to resort to actual backups in years thanks to this. also very easy to maintain that your primary backup is "working" as it's always online :)
We weren't running slaves due to lack of hardware, but have new servers in the purchase pipeline for next month or so... The plan was to run a slave basically like this, yeah. Of course I managed to pull this snafu off just before said migration.
