You weren't doing anything wrong in your Case A scenario. It just looks like the Feb 3rd backup failed. I'd be testing my backups at htis point to try and work out if that was an isolated incident or whether there is a systematic problem with the backup regime. Congratulations, by the way, on actually having backups. Further congratulations on having backups that you could actually restore from, even if it didn't all go entirely to plan.
