Nik - What I meant was to check if for some reason it is not physically present or getting deleted ( If you see some deletesnapshot operation for the particular snapshot ) Also is this happening consistently for all the template create operations from snapshot or is there a pattern ?

To get in sync, I deleted all snapshots on this VM, and confirmed that the snapshots were deleted from secondary storage. I then created a new snapshot.
