It all depends on the RTO you need to hit. But to the points being made here, the RTO may be different depending on the applications in your environment. Maybe the ERP system and its SQL database are all that need to come back within 1 hour of going down but the file server's RTO could be closer to 2 or 3 hours.
We talk about RTO and RPO, but I bet you in most places those are not clearly defined down to the VM / application level. If they are and you've planned accordingly, bravo.
I had an RTO of 4 days approved by the board for our EHR 10 years ago - I couldn't believe it when they said that was fine.
That's insane. Did you ever have to hand it back to them after a disaster? "Hey, this is what you said was acceptable, folks."
