Restoring virtual system instances from a snapshot image

A snapshot image represents a previously captured state of the virtual system instance.

Before you begin

Using this snapshot image, you can restore the state of virtual machines that were present in the virtual system instance to their stored state at the time the snapshot was taken.

You must be granted access to the virtual system instance or have the Workload resources administration with Full permission role to complete this task.

Note: You cannot restore a snapshot or this action is not available if:
  • You are not a hardware administrator with permission to Manage hardware resources (Full permission)
  • You are not a user with minimum write permissions and not assigned to the instance.

About this task

Using the snapshot restore function, you can restore the state information for each of the virtual machines in the virtual system instance to their state when the snapshot was taken. When you restore a virtual system instance by using a snapshot image, the current state of the virtual system instance is lost.

Any virtual machines in the virtual system instance that were added after the snapshot image was taken are still present and are unaffected when you restore the virtual system instance to its previous state.

Procedure

  1. Click Patterns > Virtual System Instances.
  2. Select the virtual system instance for which you want to restore by using its snapshot image.
  3. In the Snapshots section, click Restore to restore the virtual system instance to its previously captured state.
    The restore process does not take place instantly, and the virtual system instance is not usable while the virtual system instance is being restored. When the virtual system instance is restored from a snapshot, it is automatically stopped and placed into maintenance mode so that the monitoring processes do not start for the instance. To change the instance from maintenance mode back to regular operations, click Resume.

Results

After completing these steps, the states of the virtual machines that were part of the virtual system instance are restored to the same state as when the snapshot image was created. Virtual machines that were added after the snapshot image was taken are still present and are unaffected by this process.

What to do next

You can now access the virtual system instance you restored by using the snapshot image.
