How to Remove Protection Group Members

Updated: April 21, 2010

Applies To: System Center Data Protection Manager 2010

After a protection group is created, you might determine that some or all of the data sources in the protection group no longer need to be protected. To stop protecting data, remove the members that you no longer want to protect from the protection group. When the member is removed, DPM displays its status as "Inactive protection."

To delete protected data of any data source, you must remove inactive protection, which you can do by deleting the replica or expiring the data on the associated tapes. This frees up disk space and tapes for use by other protection groups.

To delete a protection group altogether, you must remove all the members in the protection group. Removing all members automatically deletes the protection group.

To remove a protection group member from protection

  1. In DPM Administrator Console, click Protection on the navigation bar.

  2. In the display pane, select the protection group member that you want to remove.

    noteNote
    You can select multiple members and remove them at the same time.

  3. In the Actions pane, click Stop protection of member.

  4. In the Stop Protection dialog box, choose whether you want to retain the protected data or delete it.

    noteNote
    To stop protection on co-located data sources, see Stopping Protection for Co-Located Data

    Click Retain Protected Data to retain the replica on disk with associated recovery points and tapes for the retention range. These can be deleted later.

    Click Delete protected data to delete the replica on disk and expire data on tapes. The tapes remain available for other protection groups.

  5. Verify that you want to remove the members displayed on the Replica on Disk tab. If you decide not to remove the member, click Cancel at the bottom of the dialog box.

  6. After you click Stop Protection, you cannot cancel this action. DPM displays "Inactive replica available" as the status of this member.

To remove inactive protection for a protection group member

  1. In DPM Administrator Console, click Protection on the navigation bar.

  2. In the display pane, select the protection group member for which you want to remove inactive protection.

    noteNote
    You can select multiple members and remove them at the same time.

  3. In the Actions pane, click Remove inactive protection.

  4. To delete the replica on disk, in the Delete Inactive Protection dialog box, you must select Delete replica on disk check box.

  5. Optionally select Expire the data on the tapes. The data for the selected inactive protection group members is marked for expiration. The tapes will not be marked as free until all other data has been expired.

  6. Click OK.

To remove a protection group member by using DPM Management Shell

  • Use the following syntax to remove a member from a protection group:

    Remove-ChildDatasource -ChildDatasource <ProtectableObject[]> -ProtectionGroup <ProtectionGroup> [-PassThru] [-KeepDiskData]

    For more information, type "Get-Help Remove-ChildDatasource -detailed" in DPM Management Shell.
