Result of stopping mirroring

When you end mirroring, the database server immediately frees the mirror chunks and makes the space available for reallocation. The action of ending mirroring takes only a few seconds.

Create a level-0 backup of the root dbspace after you end mirroring to ensure that the reserved pages with the updated mirror-chunk information are copied to the backup. This action prevents the restore procedure from assuming that mirrored data is still available.
