Ah, the case (pun intended) for a backup DAW machine?
I have two. It's a pain keeping them up to date, but doable. And one is a Mac so as long as I don't have to run CbB in the event my PC craps out I'm golden (myGoTo is Studio One). All my projects are backed up to the cloud from the PC so it's easy to get the last version as the last time I shut down a project. I typically pause Carbonite for two hours at a time while I'm working on projects and try to remember to unpause once I'm done, to get automatic backups.
My two computer OS drives are backed up nightly.
