if you used rsync to copy the data to a dataset, or filsystem, and then
snapshot it, all the data will be there even if changes have been done
later.  A snapshot isn't incremental, it's an image of what was there.

*** Yes, you're right.  I think I just got confused there for a bit.  So the
only missing piece for me is some sort of rolling expiration so things don't
get full due to having too many snaps...
