a unique name.
Adding or Modifying a Snapshot Policy
From the NAS Manager, navigate to Data ProtectionSnapshotsPolicies.
Add or modify a snapshot policy by selecting the appropriate NAS volume
from the dropdown menu. There are several options on this page.
•
Alert Administrator:
Sends an alert to the administrator when the
snapshot space reaches a certain percentage of the total volume size.
•
Periodic, Hourly, Daily, or Weekly:
These options can be combined to set
particular schedules. Also, each option has a number of snapshots to keep.
Therefore, it is advised to keep this number as low as possible since
creating snapshots impact system performance.
Accessing Snapshots
Once the snapshot is created, you can access a special folder from Export
or Share.
Access the special folder from UNIX under the directory called .snapshots
under each NFS Export.
Access the special folder from Microsoft Windows under the directory
.snapshots under each Share. (This integrates into Shadow Copies and
enables previous versions.)
