Is there any way to backup a Open AFS filesystem?

I see AFS support for AIX but I can't tell if it extends to Open AFS.

There is also a reference in the developerworks site that you can
compile in Support via the TSM api but aren't sure whether that is
equivalent to a TDP, or I'm barking up the wrong tree.

Anybody been through this?
