Deactivate by client
This has been mentioned before, probably in the previous incarnation of the NetBackup forum, but now we have 'Ideas', so:
"We do on occasion have the need to suspend NetBackup activity for particular clients (upgrade, maintenance etc etc) & it would be very useful to have the ability to suspend/deactivate scheduled backups on a per client basis. (Or even a per client/per policy basis if changes are being made to a particular area on a particular client).
Currently, our only or easiest option is to remove said client from each & every policy in which it resides."
