No.  I was assuming AMM on a jukebox.  That is not needed for Networker
to relabel a recyclable volume automatically.

AMM on a standalone drive is different as Davina pointed out.  I'm not
certain which you're referring to.

The full referred to by an incremental must be retained for the
incremental to be usable.  So the actual retention time for the full is
the retention period plus the length of the cycle (assuming you don't
have an error and skip a full).  Your pool must be able to handle that
much time.  If you do fulls every week, then that would add 6 or 7 days
to the length of time the data remains.

Unless something has changed recently, Networker does not maintain
separate cycle tracks.  A full in one group/instance affects the entire
client.

So you probably want to immediately schedule a full in your onsite pool
after the full in the offsite pool.  Otherwise incrementals done would
refer to the offsite full (complicating any restores).
