How do you know if your NetBackup Domain has become too large?
When NetBackup Domains grow beyond Symantec best practices guidelines, performance and manageability can begin to degrade. During my 15 years as a NetBackup backup engineer, I’ve found that the following 5 criteria are worth considering:
Catalog size - As the catalog grows, the time required to protect it can become excessive. The catalog backup is a database backup. The synchronization checkpoints and locking required for other NetBackup jobs will cause extra processing time.
Number of media servers – As the number of Media Servers grows beyond recommended values, overall performance can be impacted.
Number of EMM devices - (Media Servers, Tape Drives, Robots, Disk Pools, Storage Units, SAN Clients, Fibre Transport Devices) - The number of media servers and EMM devices has a direct relationship on the efficiency of the NetBackup environment. When the number of EMM devices and media servers grow beyond acceptable levels, NetBackup resource allocation degrades
Daily number of jobs processed - The number of jobs will eventually affect the overall performance of the system.
Number of processors (Sockets) – The physical processor count is critical in job processing, for large NetBackup environments.
