Important Considerations

NAS Load-Balancing - The Drive Pools, Storage Policies, and Subclients for NAS can be configured so that backup, restore, and auxiliary copy jobs will be spread among different MediaAgent, and thus the processor load for these jobs will occur on different machines. For more information, see Advanced - NAS iDataAgent Configuration.
