The solution to DB corruption

Here’s a question/test I’d like to know the answer to. If you have a DB backup that 880 feels is corrupt, can it be restored using the previous version still? Put another way is the DB unusable OR is 880 fussier.

Regarding backups, if you don’t actually test a restore from one then it’s not worth the name. Lost count of the times I’ve gone to support, at various orgs, for recovery from backup to find that something’s not working properly and the backups are hosed.

Edit: If you work somewhere and care about backups it’s worth requesting a recovery every 3 months or so, just to see if you can when you need to.
