What is snapshot management?

You can manage configuration snapshots for the configurations you have created on the BIG-IQ® Centralized Management system. A snapshot is a backup copy of a configuration. Configuration snapshots are created manually. This type of snapshot does not include events.

Creating a snapshot

You create a configuration snapshot to compare it to another configuration snapshot, or so you can save the current working configuration and then restore from that snapshot if needed.

  1. Log in to F5® BIG-IQ® Centralized Management with your user name and password.
  2. At the top left of the screen, select Change Management from the BIG-IQ menu.
  3. Under SNAPSHOT & RESTORE, select Access.
    The screen displays a list of Access snapshots that have been created on this device.
  4. At the top of the screen, click Create.
    The Create Snapshot screen opens.
  5. Supply the values on the Create Snapshot screen, and click Create.

The system creates the snapshot and adds it to the list of snapshots on the Snapshot and Restore - screen, including information related to the snapshot, including the date it was created, what account created it, and any description.

Comparing snapshots

You can compare two snapshots, or compare a snapshot to the configuration on the BIG-IQ® Centralized Management system to view their differences.

  1. Log in to F5® BIG-IQ® Centralized Management with your user name and password.
  2. At the top left of the screen, select Change Management from the BIG-IQ menu.
  3. Under SNAPSHOT & RESTORE, select Access.
    The screen displays a list of Access snapshots that have been created on this device.
  4. Select the check box to the left of each of the two snapshots to be compared.
  5. Click Compare.
    The Differences screen opens.
  6. Analyze the configuration differences between the two snapshots, When you are finished, click Cancel to close the Differences screen, then click Close.
    The screen closes and you return to the Snapshot and Restore - screen.

Restoring 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 when users restore a configuration from a snapshot. Objects are retained in the BIG-IQ configuration and are not deployed to BIG-IP® systems. 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.

Important: 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 Access component can require a restore of other dependent modules.
  1. Log in to F5® BIG-IQ® Centralized Management with your user name and password.
  2. At the top left of the screen, select Change Management from the BIG-IQ menu.
  3. Under SNAPSHOT & RESTORE, select Access.
    The screen displays a list of Access snapshots that have been created on this device.
  4. Select the check box to the left of the snapshot to use to restore the current working configuration to the configuration of the snapshot.
  5. Click Restore.
    The Restore snapshot to Working Configuration screen opens.
  6. Click Restore to restore the configuration in the snapshot and have it replace the working configuration.
  7. Click Restore in the popup screen to confirm that you want to restore the configuration, or click Cancel in the popup screen to stop the restore process for this the snapshot.
    You can also click Cancel after starting the restore process to roll back the restore.
