MSDP-C cache size recommendation

In NetBackup 11.1 environments where parallel stream/read is enabled, backups of large disk workloads may appear slower.

The parallel stream cloud VM backup performance may change with MSDP-C storage cache size configured on the storage server. MSDP-C does not use a dedicated cache volume. Instead, it temporarily uses available free space on the MSDP server when needed. By default, MSDP-C requires at least 1 TB of free space per cloud tier, which can be configured in the contentrouter.cfg file.

Because cloud data sizing and performance depend on specific customer environments and workloads, exact recommendations may vary. Therefore, sizing should be tailored to individual needs.

For detailed MSDP sizing, refer to the Cloud Tier Sizing and Performance topic of the NetBackup Backup Planning and Performance Tuning Guide.
