The agent based backends use an agent process to interact with the
backend DNS server as opposed to directly talking to them over a
management protocol. I wasn't part of the project when the agent based
BIND9 backend was added, so I don't have the full context of why there
is an agent for BIND9.
I will note that all of the agent based backends are in the "untested"
or "experimental" category:
Since the agent based drivers don't have many contributors now, I
would expect to see more of them marked deprecated and removed in a
I would highly recommend you use the native backend if possible.
