I don't quite know what you mean by borderline, so I don't know whether or
not I am disagreeing with you. Anyway, target sessions is what it says, a
target rather than a limit. If your server and client parallelism settings
allow it, in the example above there is one more session than the sum of
the target sessions. NetWorker will certainly write this session to one of
the drives, but to the best of my knowledge there is no rule that says
which drive. It is just as likely to be the drive with target=1 as one of
the drives with target=4. One of the drives will exceed the target - which
one is undefined.
