Thanks all, I will backup the model as well since it seems like it won't hurt. I will handle that backup manually since we are not modifying it. If I ever find the urge to modify it I will take another backup.

Take a flat file copy of the resource database files on every upgrade, they are files on disk so can get corrupted. It certainly does contain data worth holding onto, it contains all the system metadata and SQL will not operate without it.
I assume you are just copying the mssqlsystemresource files and that's it? Then if and when you need to restore you just copy it back in.
