We have established two main targets

• service [S_in_person] is working in less than 4 hours (RTO = 4h)
• service [S_remote] is working in less than 1 day (RTO = 1d)

The scenario is a disaster where

• the facilities are ready
• data backup can be recovered in 30m
• the remote archive is available
• technical services are ready
  this is a peculiar way of stating that these are virtual assets, only useful to structure the tree

As operational objectives (rebuild plan) we have marked the following

• in 20m the server and the firewall will be ready
• in 1h, the software will be working
• in 4h, working PCs will be ready

The plan is not complete: to recover the second service, we need to re-establish the Internet connection
