Limitations and considerations

You can set up a NAS-Data-Protection policy for your workloads.

Note:

If you use cloud as a storage unit, you must configure appropriate buffer size. Refer to the NetBackup Cloud Administrator's Guide.

Note the following important points about NAS-Data-Protection policy.

  • The NAS-Data-Protection is not supported in the DNAT environment.

  • This policy does not support copy-based retention for Snapshot images. Ensure that you carefully plan your policy scheduling and snapshot retention in SLP.

  • Client side deduplication is not supported for NAS-Data-Protection policy.

  • Vendor Change Tracking (VCT) and Accelerator options are mutually exclusive for NAS-Data-Protection policy. You cannot enable both. Veritas recommends that you do not toggle the policy with these options between different execution of this policy.

  • Vendor Change Tracking (VCT) enabled backup with incremental schedule requires base snapshot copy to determine the difference between current snapshot copy and base snapshot copy. Differential incremental schedule refers to base snapshot copy from previous differential incremental or cumulative incremental or full schedule. Cumulative incremental schedule refers to base snapshot copy from previous cumulative incremental or full schedule. During VCT enabled backup with incremental schedule, if the base snapshot copy is not available then the backup operation might fail with the error shown in Activity Monitor Detailed status.

  • NAS-Data-Protection policy is a snapshot enabled data protection policy. You can configure only storage lifecycle policy (SLP) against policy's storage destination. Additionally, the SLP should always have Snapshot as the primary job and Backup from Snapshot as secondary job.

  • If the NAS-Data-Protection policy is used in a backup host that is running antivirus software, the parent backup from snapshot job might hang.

    The antivirus software may block NetBackup process interactions causing the processes to hang. In this particular scenario, the nbcs process on the backup host might hang resulting in the backup-from-snapshot job to hang. Create an antivirus exclusion for nbcs on the backup host.

    To cancel the hung job:

    • Note down the process ID of the nbcs process which is running on the backup host. This can be obtained from the job details section.

    • Log in to the backup host and manually kill the nbcs process.

    • Refer to the Technote for more details regarding how to exclude the NetBackup processes from virus scanning: https://www.veritas.com/support/en_US/article.100004864

    • If the above steps cannot resolve the issue (and the nbcs hang persists), uninstall the network component from antivirus. On Symantec Endpoint Protection, this is called the "Network and Host Exploit Mitigation" component.

  • For NAS-Data-Protection policy, multiple images are created for a single volume that is backed up. The number of images is equal to the value configured for the Maximum number of streams per volume in the policy. Since a single image cannot be referred from a single volume, NetBackup groups the images associated with a volume. When an operation is performed on one of the images in a volume, the same operation is also performed on the other grouped images in the volume. For example, if Maximum number of streams per volume is set as four and you select one image for a volume to expire, the other three images also expire. The image grouping is applicable for the following operations:

    • Browse and Restore

    • Image expiration

    • Image import

    • Image duplication

    • Image verification

    • Set primary copy

      Note:

      Image grouping is not applicable for importing images as part of Image Sharing operation.

  • To enable checkpoint restart for NAS-Data-Protection policies created before upgrading to version 9.0, you must select the Take checkpoints every check box and enter a value in minutes.

Note:

The NAS-Data-Protection policy cannot be configured using the NetBackup web UI.
