CPU considerations
Each running process consumes certain amount of CPU cycles. The main processes consuming CPU cycles include NetBackup processes such as bptm, bpdm, and MSDP spoold, spad, mtstrmd, and vpfsd if Universal Share and Instant Access are used. More concurrent jobs correspond for more bptms, bpdms processes running at the same time, and more active threads in spoold, spad, mtstrmd and vpfsd.
For target deduplication, segmentation, fingerprint calculation and lookups are done on the same host running spoold, spad and vpfsd. More target deduplication jobs use more CPU cycles from the host. When a media server is bottlenecked on CPU, network and/or memory, adding one or more NetBackup load balancing fingerprinting media servers and/or NetBackup Client Direct (client-side deduplication) ease the CPU, memory and network pressure by offloading some data segmentation and fingerprint calculations to the new server.
