That's an interesting problem. I guess a proper solution would involve 
interrogating the database and so on, which I wouldn't know how to do, 
but I can think of a manual solution:

Create a new storage group with a new folder, and change the recording 
rules for your important programs to place their recordings in the new 
group. Now you can setup your backup solution to just backup the new 
folder rather than everything.

Note that there isn't currently a way in the GUI to move recordings from 
one storage group to another, so if you want to move existing recordings 
you'll have to move them manually, if you can find out the filename.
