Storage Policy Copy - Configuration

Table of Contents

Modifying the Copy Name

To modify the name of a storage policy copy:

  1. From the CommCell Browser, expand Policies | Storage Policies | <Storage_Policy>.
  2. Right-click the appropriate storage policy copy, and then click Properties.
  3. In the Copy Name box, type the name, and then click OK.

Marking the Copy as Inactive

You can mark the storage policy copy as inactive to prevent data transfer from a storage policy copy to a media.

The primary copy cannot be marked as inactive. In order to mark a primary copy as inactive, you need to promote the synchronous copy as a primary copy.

If you mark a storage policy copy as inactive, your primary copy data can still be pruned without being copied and the copy cannot be used to transfer data to media.

To mark the storage policy copy as inactive:

  1. From the CommCell Browser, expand Policies | Storage Policies | <Storage Policy>.
  2. Right-click the appropriate storage policy copy, and then click Properties.
  3. In the Copy Properties dialog box, clear the Active check box to disable the storage policy copy, and then click OK.

Setting Up the Storage Policy Copy to be the Primary Copy

Consider the following before promoting the storage policy copy as primary copy:

  • We recommend you to synchronize the secondary copy with the primary copy before it is promoted. If the secondary copy is not synchronized, there could be a potential data loss.
  • Make sure to verify that if secondary copy has a spool copy as its source. If it is, then make sure that this spool copy is associated as a source to another (or additional) synchronous copy also with all the same client associations.

    We recommend you to verify this before promoting a copy because if no additional synchronous copies are assigned to a spool copy, then the pruning for that spool copy will not happen and results in disk fill up.

  • We recommend not to promote a secondary copy to be the primary copy while a backup, restore, or Auxiliary Copy jobs are running.
  • The retention period of a copy is retained when promoted. Therefore, we recommended that you change the retention period of other copy (or copies) so that it has its retention period greater than or equal to the retention period of the current primary copy.

To promote a storage policy copy as a primary copy:

  1. From the CommCell Browser, expand Policies | Storage Policies | <Storage_Policy>.
  2. Right-click the appropriate storage policy copy, and then click Properties.
  3. In the Copy Properties dialog box, select the Primary Copy check box and click OK.

    A message appears that ask if you want to override the existing primary copy.

  4. Click Yes.

Enabling Parallel Copy on a Storage Policy Copy

You can configure the storage policy copy as a parallel copy to optimize the use of storage media, and decrease the time needed to run an Auxiliary Copy operation.

When an Auxiliary Copy job is run, a parallel copy generates multiple secondary copy jobs (jobs based on the number of parallel copies configured in the storage policy) concurrently. That is, the data is read from the source copy (only once) and written to the multiple storage policy copies. Therefore, multiple copies are written in parallel by reading the source media only once.

Review the following before configuring the parallel copy:

  • The parallel copy must be enabled on at least two storage policy copies in a Storage Policy for it to be effective.
  • Parallel copy can be used in an environment where you have multiple copies using identical network speed.

    Parallel copy is not recommended in environment where one copy is configured on a high speed network and the other is configured on a low speed network. In this scenario, the throughput achieved from the low speed network will be the throughput of the Auxiliary Copy job.

    For example, parallel copy operation is not advisable in an environment:

    • Where you have one copy configured on WAN and other copy on LAN.
    • Where one copy uses LTO5 tape and drives and other copy uses LTO4 tape and drives.
  • The Auxiliary Copy operation must be performed to all the parallel copies configured in the storage policy.

To enable parallel copy on a storage policy copy.

  1. From the CommCell Browser, expand Policies | Storage Policies | <Storage_Policy>.
  2. Right-click the appropriate storage policy copy, and then click Properties.
  3. In the Copy Properties dialog box, select the Enable Parallel Copy check box, and then click OK.

    When you subsequently run the Auxiliary Copy operation, make sure to select All Copies option in the Auxiliary Copy Job Options dialog box, so that the data is copied to both the copies.

Enabling Inline Copy on a Storage Policy Copy

An Inline Copy allows you to create additional copies of data at the time of backup. An Auxiliary Copy operation is not required to replicate the data from the primary copy to synchronous copy. An Inline copy enables efficient utilization of the media drives and reduces the delay in the offsite storage of the data.

  • The MediaAgent for an inline copy must be the same as the MediaAgent for the Primary Copy.
  • The deduplication on an Inline Copy is not supported if Multiplexing is enabled on the Primary Copy.
  • Inline Copy is not supported for source-side deduplicated storage policy copies.

To enable Inline Copy on a storage policy copy:

  1. From the CommCell Browser, expand Policies | Storage Policies | <Storage_Policy>.
  2. Right-click the appropriate storage policy copy, and then click Properties.
  3. In the Copy Properties dialog box, select the Enable Inline Copy check box, and then click OK.

Managing Resources for the Inline Copy

By default, the appropriate resources (for both primary and inline copies) must be available for the backup operation to complete successfully. If resources are not available for either copy, the job will go into a waiting state until resources are available. Inline Copy will never interrupt other jobs for resources needed for inline copy.

If the available resources are enough only for the primary copy, follow the steps given blow to perform the backup operation without the inline copies:

  1. From the CommCell Browser, expand Client Computers | <Client> | <Agent> | Backup Set.
  2. Right-click the appropriate subclient, and then click Backup.
  3. In the Backup Options for Subclient dialog box, click Advanced.
  4. In the Advanced Backup Options dialog box, click the Media tab, and then clear the Wait for Inline Backup Resources check box.
  5. Click OK and then click OK to close the Backup Options for Subclient dialog box.

Enabling WORM Copy on a Storage Policy Copy

WORM Copy is an option that prevents the deletion of data that is not qualified for aging. The expiration date for the read-only is set to match the data retention time established in the storage policy copies. These archive files cannot be modified or deleted by any user or application until the specified retention date. Once the retention expires, the system deletes the archives as part of Data Aging.

Once you create a WORM Copy, the following rules are enabled:

  • WORM Copy cannot be cleared.
  • The data retention on the WORM Copy can be increased but cannot be lowered.

To enable WORM Copy on a storage policy copy:

  1. From the CommCell Browser, expand Policies | Storage Policies.
  2. Right-click the appropriate storage policy copy, and click Properties.
  3. In the Copy Properties dialog box, select the WORM Copy check box, and then click OK.

    A warning message, indicates that you cannot convert this copy to a regular copy.

  4. Click Yes to continue.

Modify the Retention Criteria of the Manually Retained Jobs

The retention period of the jobs that are retained based on the WORM Copy retention cannot be changed.

You can change the retention period of the manually retained jobs associated with a WORM Copy. To change the retention period, a user must be a member of the Master user group. See Managing User Groups for more information on user groups.

  1. Enable Allow administrators to lower job retention on WORM copies option.
    1. On the ribbon in the CommCell Console, click the Storage tab and then click Media Management.
    2. Click the Data Aging tab, enable Allow administrators to lower job retention on WORM copies option by setting the value to 1, and then click OK.
  2. Modify the Retention period of a job as followed:
    1. From the CommCell Browser, expand Policies | Storage Policies | <Storage_Policy>.
    2. Right-click the appropriate WORM Copy, point to View and then click Jobs.
    3. In the Job Filter for Storage Policy dialog box, clear the Specify Time Range check box, and then click OK.

      A list of jobs associated with a storage policy copy is displayed in the Jobs for Storage Policy Copy pane of the CommCell browser.

    4. Right-click the appropriate retained job displayed with icon, and then click Change Retention.
    5. In the Manual Retention End Time for Job dialog box, select one of the following setting, and then click OK.
      • By default, Retain Until is selected, click down arrow button to change the retention date.
      • Select Infinite to not age the job.
      • Select Do Not Retain Job to not retain the job.
      The expiration date will be displayed in Retain Until field in the Jobs for Storage Policy window.

Preventing Jobs from Being Pruned

By default, when you run the Auxiliary Copy job, the jobs from the spool copy are pruned automatically.

You can change the default settings as follows:

  1. From the CommCell Browser, right click the <CommServe Node>, and then click Properties.
  2. In the CommCell Properties dialog box, click the Additional Settings tab, and then click Add.
  3. In the Add Additional Settings on Windows Client dialog box, in the Name box, type AUXCOPY_NOT_PRUNE_SPOOL_COPY.

    The Category and Type details are automatically populated.

  4. In the Value box, type 1.

    The default value is 0. If you set the value as 1, the Auxiliary Copy job will not prune the jobs from the spool copy.

  5. Click OK and then click OK to close CommCell Properties dialog box.

Modifying the Frequency of Job Pruning

By default the auxiliary copy operation will prune jobs from the spool copy every hour and upon completion of the auxiliary copy operation. You can change the frequency of job pruning as follows:
  1. From the CommCell Browser, right-click the <CommServe Node>, and then click Properties.
  1. In the CommCell Properties dialog box, click the Additional Settings tab, and then click Add.
  2. In the Add Additional Settings on Windows Client dialog box, in the Name box, type AUXCOPY_MARKCOPIED_MINUTES.

    The Category and Type details are automatically populated.

  3. In the Value box, type the number of minutes after which you want to prune the jobs.
  4. Click OK and then click OK to close CommCell Properties dialog box.

Changing the Scratch Pool Associated with the Copy

A scratch pool is a repository of media that are available for use.

To change the scratch pool of the storage policy copy:

  1. From the CommCell Browser, expand Policies | Storage Policies | <Storage_Policy>.
  2. Right-click the appropriate storage policy copy, and then click Properties.
  3. In the Copy Properties dialog box, from the Scratch Pool list, select a scratch pool, and then click OK.

Specifying Date for Selecting Backups for the Copy

By default, all backups from the source storage policy copy is copied to secondary copy. This backup selection date determines the effective start date where the storage policy copy will become active.

To select backups after a specific date for the copy:

  1. From the CommCell Browser, expand Policies | Storage Policies | <Storage Policy>.
  2. Right-click the appropriate storage policy copy, and click Properties.
  3. In the Copy Properties dialog box, click the Copy Policy tab, select the following settings and then click OK.
    1. Clear All backups checkbox.
    2. Select a date from the Backups On And After.

    This date can be on, before, or after the current CommServe date. When the date entered is after the current CommServe date, jobs that are to be copied, as well as partially copied jobs will be disabled for copy.

    You can only move the Backups On And After Date forward for a storage policy copy once it has been defined. This date must be a date which occurs after the date you originally selected.

    If you change the Backups On And After Date to a date after the one selected, all backups that were to be copied from the primary copy before the new date will not be copied when an auxiliary copy is run.

Specifying the Source for the Copy

A source copy is a storage policy copy from which data is read and copied to secondary copy during Auxiliary Copy operations. By default, the source copy to all synchronous copies is a primary copy.

Before specifying the source copy, make sure that both the storage policy copies have same CommCell entities (clients, agents, subclients and so on) associated, or this copy has a fewer CommCell entities associated than the source copy.

To specify the source copy for the storage policy copy:

  1. From the CommCell Browser, expand Policies | Storage Policies | <Storage_Policy>.
  2. Right-click the appropriate storage policy copy and then click Properties.
  3. In the Copy Properties dialog box, click the Copy Policy tab, select the following settings and then click OK.
    1. Select the Specify Source for Auxiliary Copy check box
    2. From the list, select the storage policy copy.

Assigning CommCell Entities to a Storage Policy Copy

You can select a specific client, agent, backupset/instance or subclient to be associated with a storage policy copy.

When selected:

  • Only new backup jobs of the chosen CommCell entities will be copied to the storage policy copy during an Auxiliary Copy operation.
  • Any new subclients created under the client will not automatically get assigned to this storage policy copy.

    You must manually select the subclient to copy the data. You can select multiple subclients, backupsets or clients.

The selected node is highlighted with solid icon and the nodes under the selected entity is highlighted with an arrow icon.

To associate CommCell entities (such as subclients, agents, backupsets and so on) to the storage policy copy::

  1. From the CommCell Browser, expand Policies | Storage Policies | <Storage_Policy>.
  2. Right-click the appropriate storage policy copy and click Properties.
  3. In the Copy Properties dialog box, click the Associations tab, specify the following entities and click OK.

    All the clients associated to the storage policy is displayed. By default, Client Computers box and all clients are selected.

    • To select specific client, clear the Client Computer box and then select the <Client> from which the data should be copied.

      When selected, any new entity (agent or backupset/instance or subclient) for the selected client will automatically get associated to the storage policy copy.

    • To select agent, clear the Client Computer box, expand <Client> and select <Agent>.
    • To select backupset/instance for a specific client, clear the Client Computer box, expand <Client> select backupset/instance.
    • To select specific subclient, clear the Client Computer box, expand <Client>|<Agent>|<Backupset/Instance> and then select subclient.
