Cloud Backup and Recovery

Public cloud backup

Manage backup plans

A backup plan links backup sources and backup policies. You can create a backup plan to enable scheduled automatic backups of backup sources. This document explains how to create and manage backup plans on the CBR console, including operation methods and precautions.

Prerequisites

The target backup source must exist; otherwise, create an ECS full backup source first.

The target backup policy must exist; otherwise, create a backup policy first.

Limitations

A maximum of 300 backup plans can be created per account in the same region.

A single backup plan supports adding up to 300 backup sources.

Precautions

Backup performance SSD is not supported; performance SSDs belong to the previous generation of cloud products and are gradually discontinued.

A single backup source supports up to 10 recovery points (including manual and automatic backup recovery points). When the number of recovery points exceeds 10, backups cannot proceed and recovery points must be deleted first.

Only one active task (backup or restore) can exist for a single backup source at a time. New tasks automatically queue, with a maximum queue length of 2; tasks exceeding this limit will fail to create.

Create a backup plan

Select the target region in the top navigation bar.

In the left navigation bar, select Backup Plan to enter the Backup Plan page.

Click Create Backup Plan.

In the Create Backup Plan panel, configure backup plan parameters as follows:

Parameter items	Is it mandatory	Parameter description
Basic information
Backup Plan Name	Yes	Set the name of the backup plan. The naming rules are as follows: Start with a letter, Chinese character, or underscore (_). Can include letters, Chinese characters, numbers, underscores (_), and hyphens (-). The length must be between 1 and 128 characters.
Select backup source	is	Add a backup source by following these steps: Select the backup source type as ECS whole machine. Select the ECS backup source. tip Backup sources associated with other backup plans cannot be selected. The same backup source can be linked to only one backup plan at the same time. Select the cloud disk to back up. By default, all cloud disks mounted on ECS instances are automatically backed up. You can uncheck automatic backup for all cloud disks mounted on ECS instances according to your business needs, then select at least one cloud disk to back up from the list below. tip Performance SSDs are not supported; they belong to a previous generation of cloud products and have been gradually discontinued. Repeat the above steps to add multiple backup sources; a single backup plan supports up to 300 backup sources. Click Add backup source and follow the above steps to add multiple backup sources in the current backup plan. A single backup plan supports up to 300 backup sources.
Backup Policy	No	Select a backup policy. tip If the available policies do not meet your needs, click Backup Policy dropdown menu and select Create Backup Policy to go to the Backup Policy page to create one. For detailed steps, see Create Backup Policy. After creating the policy, return to the Create Backup Plan page, click the Refresh icon to the right of the Backup Policy dropdown menu, then select the newly created backup policy from the list. If no backup policy is selected or the chosen policy is disabled, the system will not automatically back up the specified backup sources after successfully creating the backup plan.
Backup storage space
ECS	Yes	The storage location of the backup data depends on the backup data storage method of the backup source. ECS full machine backup relies on the cloud disk snapshot service. The backup storage space is managed by the cloud disk snapshot service. For detailed information about cloud disk snapshots, see Cloud Disk Snapshot.

Click Confirm.

After successfully creating the backup plan, the system automatically backs up all backup sources in the plan according to the configured policy.

Actions	Instructions	Operation steps
Query backup plans	Supports querying the target backup plan in the backup plan list by Backup Plan ID, Backup Plan Name, or Backup Source ID.	On the Backup Plan page, click the query condition dropdown menu (located at the top right corner), and select a query condition. Enter the corresponding keywords in the search box based on the selected query criteria.
Edit backup plan	Modify the backup source and backup policy associated with the backup plan. tip Editing the backup plan does not affect any automatically running backup tasks it has generated. Editing the backup plan does not affect existing stock recovery points. They will be retained and deleted according to the retention rules effective at the time the backups were made.	On the Backup Plans page list, click Edit in the Actions column for the target plan. In the Edit Backup Plan panel, configure the backup sources and backup policies. For parameter details, see Create Backup Plan. Click Confirm.
Delete backup plan	After deleting a backup plan, the system no longer performs automatic backups for the related backup sources. tip Deleting a backup plan does not affect any automatic backup tasks generated by it that are currently running. Deleting a backup plan does not affect existing recovery points. Existing recovery points are retained and deleted according to the retention rules effective at the time the backup occurred.
