No, but I'd probably consider something like log shipping to a tertiary (maybe an hour behind primary) for the 'must be up in 2 hours', rather than jumping through hoops with tweaking backups. But then, last system I worked on with requirements like that was over 1 TB and restoring backups was a 4-6 hour process.
