Create a Snapshot Policy

An automatic snapshot policy enables the system to automatically create snapshots at user-defined intervals. We recommend that you avoid business peak hours when creating an automatic snapshot. This article describes how to create an automatic snapshot.

Restrictions

You can configure a maximum of four snapshot policies for one disk.

Procedures

1.  Log in to the Dedicated Host Console.

2.  In the left navigation pane, click Dedicated Disk to enter the Disk page.

3.  Select the target region, and then click the name of the target disk.

4.  On the Disk Information page, click Create Automatic Snapshot Policy in the Automatic Snapshot Policy area.

5.  On the Create Automatic Snapshot Policy page, create an automatic snapshot policy as described in the following table.
