I haven't tried, but wouldn't it be possible to just take a snapshots
from a LV containing an encrypted filesystem, and then loop-mount it
(assuming encrypted via the loop device), give the password, and then
backup ?

I think from the loop-aes type of filesystem encryption point of view.
But as I have said previously, I haven't tried if this works, although
if my understanding of all these things is OK, should work.

I will try to test this setup tomorrow when I get to work :-)
