Guidance:
When a volume is brought online or reverted to a snapshot, the volume snapshot driver scans for and activates any persistent snapshots that may be on the volume.  Some snapshots may be marked 'visible', meaning they were exposed as a local volume or file share.  Some detected snapshots may be marked 'deleted', meaning they are no longer available for use and their diff area space will be reclaimed when all older snapshots are deleted.  Look for instances of event 106 to see each snapshot that was discovered and whether it was 'visible' or 'deleted'.

You should expect this event when a volume is brought online or reverted to a snapshot.  No user action is required.
