Create an automatic snapshot policy

This topic describes how to create an automatic snapshot policy in the 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 page, click Create Policy.
6. In the Create Policy dialog box that appears, configure the following parameters as prompted.
   • Name: specifies the policy name.
   • Executed At: Select one or more points in time from 00:00 to 23:00.
     Note Creating a snapshot may temporarily reduce the I/O performance of a block storage device by about 10%. We recommend that you create snapshots during off-peak hours.
   • Execution Frequency: Select one or more days of the week.
   • Keep Snapshots: specifies the number of days to retain the snapshot. Valid values: 1 to 65,536. Default value: 30. If you select Always Keep and the maximum number of snapshots is reached, the system will delete the earliest automatic snapshot.
