Directry level restore is not possible form snapshots.
the easiest way is browse though the snapshot, find the directory you want.
copy and paste-replace or copy as paste-new-dir-name.
If the copy operation going to take a while, ill recommend you rename the snapshots
In Ontap 7-Mode snapshots are named hourly.0 or daily.0
if the copy operation going to take more than hour, before it complete your hourly.0 could
renamed to hourly.1 by ontap, and your copy operation will fail. To avoid that rename the snapshot to something thats not use by ontap.
