About configuring a favorable client-to-server ratio
For a favorable client-to-server ratio, you can use one disk pool and configure multiple storage units to separate your backup traffic. Because all storage units use the same disk pool, you do not have to partition the storage.
For example, assume that you have 100 important clients, 500 regular clients, and four media servers. You can use two media servers to back up your most important clients and two media servers to back up your regular clients.
The following example describes how to configure a favorable client-to-server ratio:
Configure the media servers for AdvancedDisk and configure the storage.
Configure a disk pool.
Configure a storage unit for your most important clients (such as STU-GOLD). Select the disk pool. Select . Select two media servers to use for your important backups.
Create a backup policy for the 100 important clients and select the STU-GOLD storage unit. The media servers that are specified in the storage unit move the client data to the storage server.
Configure another storage unit (such as STU-SILVER). Select the same disk pool. Select . Select the other two media servers.
Configure a backup policy for the 500 regular clients and select the STU-SILVER storage unit. The media servers that are specified in the storage unit move the client data to the storage server.
Backup traffic is routed to the wanted data movers by the storage unit settings.
Note:
NetBackup uses storage units for media server selection for write activity (backups and duplications) only. For restores, NetBackup chooses among all media servers that can access the disk pool.
