One week ago you performed a single file SnapRestore from a snapshot other than the most recent. You now notice that the storage appliance is taking longer to perform snapshot deletions. Which of the following reasons is the most likely cause of this problem.

A.
Snapshots that existed after the one used for the single file SnapRestore must be manually deleted.

B.
The SnapRestore schedule changed from weekly to hourly.

C.
All of the snapshots created after you did the single file SnapRestore were deleted, and reserved inodes from the snapshots still exist.

D.
Before a snapshot can be deleted, the active maps acroos all snapshots need to be checked for active blocks related to the file you restored.
