Create an automatic snapshot policy

This topic describes how to create an automatic snapshot policy in the Elastic Compute Service (ECS) console.

1. Log on to the ECS console.
2. In the left-side navigation pane, choose Storage & Snapshots > Snapshots.
3. In the top navigation bar, select a region.
4. On the Snapshots page, click the Automatic Snapshot Policies tab.
5. In the upper-right corner of the Automatic Snapshot Policies tab, click Create Policy.
6. In the Create Policy dialog box, configure the parameters described in the following table for the automatic snapshot policy.

   Parameter	Description
   Name	The name of the automatic snapshot policy.
   Executed At	The hours of the day at which to create automatic snapshots. You can select one or more hours from 00:00 to 23:00. Note When a snapshot is created for an Elastic Block Storage (EBS) device, the I/O performance of the device can degrade by as much as 10%. This can result in a transient I/O speed decrease. We recommend that you create automatic snapshots during off-peak hours.
   Execution Frequency	The days of the week on which to create automatic snapshots. You can select one or more days from Monday to Sunday.
   Keep Snapshots	The retention period of the automatic snapshots. The default retention period is 30 days. The following options are available: Keep For: The snapshots are retained for the specified number of days. Valid values: 1 to 65536. Always Keep: If the maximum number of automatic snapshots for a disk is reached, the earliest snapshot created based on the automatic snapshot policy is deleted when a new snapshot is created.
   Tag	Select existing tag keys and values, or enter new tag keys and values. Automatic snapshots created based on the automatic snapshot policy have these tags added. Note You cannot modify the tags added to the automatic snapshot policy after the policy is created. We recommend that you properly plan tags.
   Cross-Region Replication for Snapshots	If the Cross-Region Replication for Snapshots feature is enabled, automatic snapshots that are created based on the automatic snapshot policy are copied to the destination region. After you select Enabled, you must specify the Destination Region and Retention Time of Snapshot Copies parameters. For information about the regions that support snapshot copying and the billing rules of snapshot copies, see Copy a snapshot and Snapshots.
   Destination Region	The region to which to copy the snapshots.
   Retention Time of Snapshot Copies	The retention period of snapshot copies within the destination region. Keep For: The snapshot copies in the destination region are retained for the specified number of days. Valid values: 1 to 65536. Always Keep Snapshots Regardless of the Limit of Snapshots: The snapshot copies in the destination region are permanently retained.
