Do you have a passphrase on the backup?  I don't see any key use, and it
looks like gpg-agent is turned off.

On the gpg processes, could you run an strace and see what fd it is hanging
on?  "strace -p <pid>" should do it.

You can get a debug trace by doing:  DEJA_DUP_DEBUG=1 deja-dup --backup
from the command line.
