Restore some objects from a snapshot

You can restore a snapshot to change the working configuration to that of the snapshot. Restoring the snapshot merges objects from the snapshot into the BIG-IQ Centralized Management configuration and removes all active locks. No objects in the BIG-IQ configuration are removed. Once the restore process starts, you cannot modify the BIG-IQ configuration until the process is completed or canceled. If the process is canceled, all configuration settings are rolled back.
Restoring a snapshot in one component can impact other components that have dependent configuration objects. We recommend that when you restore configurations that involve multiple components, you use snapshots that were created at approximately the same time. Restoring the Local Traffic & Network component can require a restore of other dependent components.
If you are restoring a snapshot for Local Traffic & Network, Network Security, or Web Application Security, you can select specific objects to restore. This process is called
partial restore
. For example, you might have changed hundreds of configuration objects since you created a specific snapshot, but by doing a partial restore, you could bring back the settings for twenty five of them.
There is another reason you might choose to do a partial restore. With a partial restore, you can either restore the snapshot immediately, or you can create a snapshot evaluation. You can use an evaluation to review the differences between a snapshot and the current working configuration and confirm that you are restoring to the preserved configuration that you are looking for.
  1. At the top of the screen, click
    Deployment
    .
  2. Expand
    RESTORE
    , and click the component that contains the snapshot to restore.
    The screen displays a list of snapshot restores and evaluations that have been created for the selected component on this device.
  3. Under Partial Restore Evaluations, click
    Create
    .
    The New Evaluation screen opens.
  4. For
    Name
    , type a name for the snapshot restore.
  5. For
    Description
    , describe the snapshot restore.
  6. For
    Snapshot
    , select the snapshot you want to restore to.
  7. If you want to create a snapshot that you can use to get back to your current configuration after the restore, for
    Create Snapshot
    , select
    Create a snapshot prior to restoring
    .
  8. If you want the system to assess what the impact of deploying this snapshot would be on the managed devices, for
    Offline Verification
    , select
    Run offline verification after restore
    .
  9. For the
    Restore Scope
    , select
    Partial Restore
    .
    The screen displays additional settings.
  10. Click
    Add
    to specify which configuration changes to restore.
  11. On the
    Available
    tab, select the object type that you want to restore.
  12. From the list of configuration changes, select the objects that you want to restore and click
    Add
    .
  13. If there are additional object types you want to include in this restore, repeat the last two steps for each object type.
  14. If you add an object to the restore and then change your mind, you can click the
    Selected
    tab, select the object, and click
    Remove
    .
  15. When you have added all of the changes that you want to include in this restore, click
    Save
    .
    The objects you selected for inclusion are listed under Source Objects.
  16. For
    Supporting Objects
    , your options depend on the component you are restoring.
    For Web Application Security
    Supporting objects are always included.
    For Network Security or Local Traffic & Network
    Clear the
    Include
    check box if you want to restore changes only to the selected objects. It is almost always best to restore changes to the associated objects as well.
    The objects that you manage using the BIG-IQ depend on associations with other, supporting objects. These object associations form relationship trees that are sometimes quite complex. Generally, when you restore a change to a managed object it is a very good idea to include these supporting objects in the deployment. This diagram illustrates a typical relationship tree for Network Services managed objects. For Local Traffic and Web Application Security, the trees are equally complex and just as vital to include.

  17. If you decide you want to remove one of the objects selected for restoration, you can select it and then click
    Remove
    .
  18. You can either create an evaluation of the restore and review it, or restore the snapshot immediately. For
    Method
    , select
    Create Evaluation
    or
    Restore immediately
    .
  19. Click
    Create
    .
    If you selected
    Create Evaluation
    1. The confirmation screen notifies you that you are about to create an evaluation.
    2. Click
      Evaluate
      . The evaluation is added to the Evaluations list with a status of
      Pending confirmation
      .
      This process might take some time. You can cancel it if you change your mind.
    3. To review the changes between the snapshot and the current working configuration, click
      View
      .
    4. If you decide to complete this restoration, select this snapshot evaluation, and click
      Restore
      . When the restore finishes, the snapshot restore you created is listed under Restores with a status of
      Restore complete
      .
    If you selected
    Restore immediately
    1. The confirmation screen notifies you that you are about to trigger a snapshot restore.
    2. Click
      Restore
      . The restore process begins.
    This process might take some time. You can cancel it if you change your mind.
