I have considered that.  You can also do a partition-on-a-file,
and mount via loopback.  The problem is that ANY change
to the partition, and the WHOLE partition-on-a-file file gets backed up.
I'm still thinking I would run a script to maintain
a copy of the critical stuff, but every file is encrypted.
At least that way, backup load is limited to new/changed FILES.

Not a great idea, but its all I have right now...
