You've lost me. You have 1 server, with 6 AFTD devices attached. And you
have 6 pools, one each for each AFTD device. And so you have .. what, the
same client, defined 6 times, each with a different backup selection? And
each of these 6 clients is in a separate group? And you run all 6 groups
every night?
I'm still confused, sorry. :-)
