AdvancedDisk performance considerations

The entire data path between client and storage, including both hardware and software stacks, determines the overall performance of the backup and restore process. It is therefore essential that the performance of the disk storage is not considered independently of entire data path and effect of infrastructure when seeking to resolve overall performance issues.

The AdvancedDisk storage implementation relates mounted files systems within the operating system of the media server to disk volumes within NetBackup disk pools. The normal rules and guidelines related to file system configuration on the host apply and advanced file systems such as VxFS, XFS, and ZFS can be used on media servers that support them. The AdvancedDisk storage implementation enforces the fact that an AdvancedDisk disk volume is a mounted file system on the storage server. However, NetBackup does not manage the mounting and dismounting of AdvancedDisk disk volumes. Instead, mounting and dismounting is managed by the administrator and the operating system of the host.

Recommendation: Configure file systems that are used as AdvancedDisk disk volumes in NetBackup in such a way that they are automatically mounted upon startup of the operating system of the hosting media server.
