Assets configuration support for DNAS

From PowerProtect Data Manager 19.14, certain DNAS parameters from the application.yml file can be configured through the PowerProtect Data Manager UI and REST API. These configuration parameters for DNAS can be set at the policy and asset levels for the backup, restore, and File-level restore (FLR) workflows.

For example, you can configure the following parameters through the PowerProtect Data Manager UI and REST API:

  • Continue/skip the asset backup when the file/folder name length is exceeded.
  • Backup and restore timeout value.
  • Number of attempts to retry the backup for failed slices.

The PowerProtect Data Manager Public REST API documentation provides more information about the REST APIs that are added to configure the asset parameters.

NOTE:
  • Though some parameters, such as whether to continue or skip the asset backup if the file/folder name length is exceeded, can be configured at the policy level, asset-level configurations take precedence over policy-level configurations for the backup workflow.
  • Slice-related parameters such as slice size, slice file count, and depth limits can only be set through the REST API. Any modifications made to the application.yml file associated with these parameters, presented through the REST API and/or the PowerProtect Data Manager UI will be ignored.

To configure the asset parameters, perform the following:

  1. In PowerProtect Data Manager UI, select Infrastructure > Assets > NAS.
  2. Select the destination asset, click More Actions and select Assign Configurations. The Configure Asset Parameters page appears.
  3. Toggle the Disable switch to Enable. By enabling,
    • Default values are set for the asset parameters. Click Save to configure the assets with the default values.
    • You can configure the following asset level parameters:
      Parameters Description
      Backup Options
      Continue asset backup when file name character limit is exceeded Select this option to continue the backup process even if the file or folder name length exceeds the limit of 255 bytes.
      Skip Files/Folders when name character limit is exceeded Select this option to skip the backup process if the file or folder name length exceeds the limit of 255 bytes.
      NOTE:
      • This option cannot be selected without selecting the Continue asset backup when file name character limit is exceeded option as the backup cannot be processed without it.
      • The Info level troubleshooting logs contain the skipped elements detail.
      Jobs Options
      Retry Failed Slice Specify the number of attempts to retry the backup for failed slices.
      NOTE:The minimum (default) value is 0. The maximum value is 5. Selecting a value less than 0 or greater than 5 disables the Save button.
      Timeout for Unresponsive Jobs Select a timeout value for jobs that are unresponsive. When the timeout is reached, the NAS backup session is canceled.
      NOTE:The minimum (default) value is 3 hours. The maximum value is 12 hours.
  4. On configuring the required parameters, click Save. The configured changes are applied to the specific asset.
NOTE:
  • Disabling the Enable asset level parameters toggle after configuring the values will reset the asset parameter values to their original state.
  • When slice parameters, such as the slice size and slice file count that are defined at the asset level are modified using the REST API, a full backup is a must.
