AFS does not currently support encrypted volume dumps.  From my wishlist:

"The model used by many organizations for backups is offline storage of 
volume dumps.  The groups responsible for storing the dumps should not 
have access to the contents of the dumps.  Even a simple encryption 
using the existing AF Skey would be better than nothing although a more 
sophisticated key management solution for generating dumps for backups 
and later restoration would be desirable."

If this is a project that your organization would be interested in 
funding, please contact Secure Endpoints privately.
