Restore drills
A backup nobody has restored has not been proved to work. It can look complete and still fail to turn back into a wiki, and the day you find out should not be the day you need it. So Tesria proves its offsite copies on a schedule, by itself.
After every copy, each offsite target checks that the copy is complete and undamaged.
Every 30 days (
OFFSITE_DRILL_DAYS), each offsite copy is restored for real: the newest dump is taken out of it, loaded into a temporary database, counted and thrown away. Nothing live is touched.Test restore on the Backups tab does the same for the backups on this computer, whenever you ask.
The first asks whether the copy is intact; the drill asks whether it still turns back into a wiki. A copy can pass the first and fail the second, which is why a failed drill is a critical alert for every administrator. Each target’s card shows Last restore drill.
Rehearse it yourself, once or twice a year. Follow When the machine is gone on a spare computer. It is the one procedure you should not be reading for the first time when you need it.
