Manage backup strategies

Backup strategies automate backups by defining backup cycles, types, and retention rules. This document explains how to create and manage backup strategies on the CBR console, including key considerations.

Considerations

A single account supports up to 300 backup strategies per region.

Create a backup strategy

Select a region from the top navigation bar.

In the left navigation bar, select Backup Strategies.

Click Create Strategy to open the Create Backup Strategy dialog.

Configure policy parameters. The parameter descriptions are as follows:

Parameter item	Is it mandatory	Parameter description
Basic information
Policy name	yes	Set the name of the backup policy. The naming rules are as follows: Start with a letter, Chinese character, or underscore (_). May contain letters, Chinese characters, numbers, underscores (_), and hyphens (-). The length must be between 1 and 128 characters.
Enable strategy	No	Set whether to enable the strategy. If selected: enable the strategy. The system will automatically back up the backup sources in the related backup plans according to the strategy configuration. If not selected: disable the strategy.
Backup rules
Backup cycle	Yes	Set backup frequency. Weekly Repeat days: select the days of the week to run backup tasks; options include Monday to Sunday, multiple selections allowed. Execution time: select the hour of the day to run backup tasks; options range from 00:00 to 23:00 on the hour. tip For example, if you select Sunday as the repeat day and 23:00 as the execution time, the system will automatically run the backup task every Sunday at 23:00. When selecting execution times, it is recommended to choose a single time. If selecting multiple times, ensure enough interval between them to complete each backup task. Monthly Repeat months: select the months to run backup tasks; options include January to December, multiple selections allowed. Specified date: select the dates each month to run the backup task; multiple selections are supported. tip For example, if you select the recurring months as January and June and the execution date as the 1st, the system will automatically run the backup tasks on January 1 and June 1.
Backup time preview	No	Automatically display the next 10 backup times according to the backup schedule.
Backup type	is	Select the backup type, either incremental backup or full backup. tip This setting does not apply to ECS full machine backups. ECS full machine backups default to a full backup on the first run, and incremental backups thereafter.
Backup retention rule
Recovery point retention period	Yes	Select and set the retention period for recovery points in the backup storage. Automatically delete after retaining for XXX days: Set the retention period. Recovery points will be automatically deleted from the backup storage after the specified number of days.
