snapshot missing data to capture on daily schedule

Hey guys i have seen some very strange issue.

1. ONTAP 8.3.2P2 there is one volumes and contaisn one FC luns. The LUN is mounted to a windows 2012r2 where cifs are created.
2. volumes assigned the 9 days snapshot policy and create daily one snapshot.
3. i need to restore some folder/files from any of the snapshot. so i have created clone of the volumes and mouned the LUNs to windos server.
4. what i see here that snapshot did not capture the folders/files that need to restore. 
5. Is it window issue or ONTAP issue. 
6. Can anyone encounter such issue ??
7. Please let me know
