When you need to back up security group rules to meet subsequent business needs or roll back to the original rules due to new rule exceptions, you can configure a snapshot policy.
Authorize the COS service: As snapshot records are stored in a COS bucket, you need to perform read and write operations on COS. If you have not authorized the COS service when creating the snapshot policy, the system will automatically pop up a window for you to perform authorization as prompted. After performing the authorization, you can refresh the page to go to the snapshot policy page. No more authorization is required after that.
|Name||Customize the snapshot policy name, which can contain digits, letters, and special symbols.|
|Backup Policy||Operation-triggered backup and scheduled backup are supported:
|Backup start time||This parameter is displayed only when you select Scheduled Backup. The date ranges from Monday to Sunday, and the time can be accurate to the second. Up to five backup times can be added, and at least one is retained.
|Snapshot Retention||You can customize the retention period of backup records, after which the records will be deleted automatically. The maximum value is 365 days.|
|Creating COS Bucket||
|COS bucket name||A COS bucket name is in the format of Custom name - Developer app ID. A COS bucket name can contain up to 60 characters, including letters, digits, and hyphens (-). A COS bucket name cannot be changed once set.|
