PowerScale OneFS 9.8.0.0 Backup and Recovery Guide

Create a storage policy

With CommVault Simpana, you must configure a storage policy that specifies the PowerScale cluster with the data you want to back up.

1. Add and name a new storage policy.
   1. In the CommCell Browser, expand Policy.
   2. Right-click Storage Policies, and then click New Storage Policy.
   3. In the Create Storage Policy Wizard window, click Data Protection and Archiving, and then click Next.
   4. In the Storage Policy Name field, type a name for the storage policy, and then click Next.
2. Specify the PowerScale cluster containing the data you want to back up.
   1. From the Library for Primary Copy list, select the name of the NDMP library you configured previously and click Next.
   2. From the MediaAgent list, select the PowerScale cluster you want to back up data from. If necessary, also select the appropriate drive pool.
   3. Click Next.
3. From the Scratch Pool list, select Default Scratch.
4. Optional: To enable multi-streaming, specify the Number of Device Streams setting as a number greater than one and up to the number of tape devices in the library. Although OneFS supports up to 64 streams, we recommend that you do not specify more than eight device streams for performance reasons.
   NOTE:We recommend that you enable multi-streaming to increase the speed of backup operations.
5. Click Next.
6. Select Hardware Compression, and then click Next.
7. Review your storage policy selections and click Finish.
   You can monitor the progress of the backup through the CommVault Simpana user interface, or by running isi ndmp sessions list at the OneFS command-line interface.
