# View and modify snapshot policies

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

## Prerequisites

See Roles and associated permissions to determine the user roles that can perform this task.

| NOTE: When modifying snapshot policies, ensure that your system is sized for the snapshot usage that the policies will consume.

| NOTE: Any changes to a snapshot policy affect every storage group associated with that policy.

## About this task

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

Renaming a policy results in the renaming of existing policy snapshots.

## Steps

1. Select a storage system that supports snapshot policies.
2. Select Data Protection > Snapshot Policies.
3. Click on the panel of the selected policy.
4. Modify any of the following:
   - Snapshot policy name
   - Select the snapshot creation rate, interval, and offset into the interval. For example, create a snapshot hourly, every 6 hours (interval) at 05:59 (offset) into the interval.

     | NOTE: The interval cannot be greater than the offset. You can also type a value for the interval (a value not greater than the offset) if you do not want to select from the available intervals.

   - Retention details
   - Optional: Compliance values
5. Click Modify.
