# View storage group snapshot compliance details

The Snapshot policy feature provides snapshot orchestration at scale (1,024 snaps per storage group). The feature simplifies snapshot management for snapshots.

## About this task

See Understanding Snapshot policy for an overview of the snapshot policy functionality.

The Snapshot Policies tab enables you to view current and historical snapshot compliance of the storage group.

The view consists of a time graph for every snapshot policy that is associated with the storage group. The time graph represents the compliance state of the storage group snapshot policy combination. The Y-axis represents the number of snapshots that are expected to exist during the defined time window for the snapshot policy, while the X-axis is time.

When the storage group or snapshot policy is compliant, the line on the chart is green and the value of the Y-axis is the number of snapshots that should be retained. If the compliance status is warning or critical, the Y-axis value drops to the number of snapshots that are retained and the color of the graph changes to yellow, if warning, or red, if critical.

This graph enables you to easily read when the snapshots went out of compliance, how many snapshots were short of the retention amount, and if the problem is getting worse or improving over time. If you select a point on the graph where the compliance status is critical or warning, you can see the list of error messages that are generated for that compliance status in the compliance error view.

## Steps

1. Select a storage system that supports snapshot policies.
2. Select Storage > Storage Groups to open the Storage Groups list view.
3. Select a storage group that is associated with snapshot policies and click .
4. Click the icon next to Snapshot Compliance or click View All Details, click the Data Protection tab and click on the Snapshot Policies tab.
5. View the time graph for every snapshot policy that is associated with the storage group.
6. Optional: Change the time interval from Last 24 Hours (default) to any of the following - Last Week, Last Month, Last 6 Months, Last 12 months, Custom. Select Custom to set a custom date and time (see Set custom date and time for storage group snapshot compliance).
7. Select a warning or critical point on the graph to view error messages generated for that compliance status in the compliance error view.
   The following controls are available:
   - Add Snapshot Policy— Associate a snapshot policy and storage group with each other
   - Remove Snapshot Policy— Disassociate a snapshot policy and storage group from each other
   - Suspend— Suspend the snapshot policy associated with the storage group
