Adding an SLP

The operations in an SLP are the backup instructions for the data. Use the following procedure to create an SLP that contains multiple storage operations.

This section briefly describes SLP creation, for more details see NetBackup™ Administrator's Guide, Volume I.

To create an SLP

  1. Open the NetBackup web UI.
  2. On the left, click Storage > Storage lifecycle policies.
  3. Click Add to create a new SLP.
  4. On the Storage lifecycle policy pane, provide the following details:
    • Storage lifecycle policy name: The name cannot be modified after the SLP is created.

    • Data classification: Defines the level or classification of data that the SLP is allowed to process. The dropdown menu contains all of the defined classifications as well as the Any classification, which is unique to SLPs. The Any selection indicates to the SLP that it should preserve all images that are submitted, regardless of their data classification.

    • Priority for secondary operations: The priority that jobs from secondary operations have in relationship to all other jobs. The priority applies to the jobs that result from all operations except for Backup and Snapshot operations. Range: 0 (default) to 99999 (highest priority).

      For example, you may want to set the Priority for secondary operations for a policy with a gold data classification higher than for a policy with a silver data classification.

  5. Add one or more operations to the SLP. The operations are the instructions for the SLP to follow and apply to the data that is specified in the backup policy. Click Add to add operations to the SLP. Provide the following on the New operation pane. Select an Operation type.

    Source storage > Operation

    Select Backup.

    Destination storage attributes > Destination storage

    Select the required storage.

    Retention > Retention type

    • The Fixed retention indicates that the data on the storage is retained for the specified length of time, after which the backups or snapshots are expired.

      Expires immediately, 1 week, 2 weeks, 3 weeks and many more.

      An image copy with a fixed retention is eligible for expiration when all of the following criteria are met:

      • The Fixed retention period for the copy has expired.

      • All child copies have been created.

      • All child copies that are mirror copies are eligible for expiration.

    • The Expire after copy retention indicates that after all direct (child) copies of an image are successfully duplicated to other storage, the data on this storage is expired. The last operation in the SLP cannot use the Expire after copy retention type because no subsequent copy is configured. Therefore, an operation with this retention type must have a child.

    • The Capacity managed operation means that NetBackup automatically manages the space on the storage, based on the High water mark setting for each volume.

      The High water mark and Low water mark settings on the disk storage unit or disk pool determine how the space is managed.

    To add a child operation, select an operation and then click Add child. Select an Operation type. For a child operation, the SLP displays only those operations that are valid based on the parent operation that you selected.

  6. The Window tab displays for the available operation types. Use them to specify when the secondary operation runs, create a window for the operation.
  7. Optionally, select Postpone creation of this copy until the source copy is about to expire.
  8. Under Advanced, specify if NetBackup should process active images after the window closes.
  9. Under Duplication, you can allow an alternate read server to read a backup image originally written by a different media server.
