Recently, I ran this on my notebook (/secure/ is an encrypted partition):

tar -cf - /secure/ | gzip -9 | gpg -c > /media/usb/backup/secure.tar.gz.gpg

I think I typed that up correctly, the notebook was wiped and reinstalled 
(newer distro releases) since then, so I don't have that line in my history 
anymore.

Later today, I'll run this (after creating a new encrypted partition for it):

gpg -d /media/usb/backup/secure.tar.gz.gpg | tar -zxf -

Or, as I just read Clint's post about how GNU tar will actually figure out to 
use the right decompression on it's own:

gpg -d /media/usb/backup/secure.tar.gz.gpg | tar -xf -

HTH.
