Yes you are correct that backing up the main interface will not help if the remote side of the frame connection goes down, you will still be up up to your local switch. since I think 10.2 or 3 you can backup the subinterface, it recognizes the PVC being down and will initiate you backup though I prefer triggering backups on loss of routes personally.
