More than one backup job per second

Starting from NetBackup 8.2, NetBackup removed the one backup job per second limitation within a primary server. With the change, the limit of starting only one job per second still holds for a single client, however, multiple jobs from different clients may be started within a second. NetBackup can scale to higher job counts with appropriate hardware resources.

Multiple backup jobs from multiple clients all starting at the same time may cause a temporary CPU and memory usage surge, sometimes significantly. The overall performance effect maybe marginal, however, if primary server is already CPU-bound or memory-bound, this temporary surge can cause the system to become unresponsive.
