 We have some save-sets that take upwards of 13 to 15 hours to complete
(100+ GB).
 The thing that will change in the 5 or 10 minutes would be the rate
it's writing at and/or the amount of data written so far... (if they can
be captured ??).

 If via this methodology you can capture the fact that a session has
'hung' , tell me exactly what corrective actions you would take to
address it before the group completes ??? There's not much you can do
until that happens... And if the session is truly hung, it should
time-out eventually (and maybe get re-tried) before the group completes.
It may not get re-tried without some kind of human intervention... The
only solution I can think of is to have people very knowledgeable about
Networker 'actively monitoring' your backups from start to finish (i.e..
Operations), that can recognize a problem as soon as it occurs and take
immediate corrective action.
