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 1. Log in to the [Volcano Engine Cloud Backup Console](https://console.volcengine.com/cbr/region:cbr+cn-shanghai/resource/ecs). 2. Select a region from the top navigation bar. 3. In the left navigation bar, select **Backup Strategies**. 4. Click **Create Strategy** to open the **Create Backup Strategy** dialog. 5. 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.

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.

* **Retain indefinitely**: Recovery points will be retained indefinitely in the backup storage.

tip

Recovery point retention time applies only to automatic backup recovery points generated by the backup policy and does not apply to manual backup recovery points from the same backup source.

| 6. Click **Confirm**. ## Related actions |Actions |Instructions |Operation steps | |---|---|---| |Query backup policy |Supports querying target backup policies in the backup policy list by **backup policy ID** or **backup policy name**. |1. On the **Backup Policy** page, click the query condition dropdown list (located at the top right) and select a query condition.

2. Enter the backup policy ID keyword or policy name keyword in the search box based on the selected query condition. | |Enable/Disable backup policy |Supports manually enabling and disabling backup policies.

After disabling a policy, automatic backup tasks applied by that policy cannot be executed.

tip

Enabling or disabling the backup policy does not affect existing recovery points. The existing recovery points will be retained and deleted according to the retention rules in effect when the backup occurred.

Enabling or disabling the backup policy does not affect ongoing automatic backup tasks generated by it.

|* **Disable policy**

1. On the **Backup Policy** page list, click **Disable** in the **Actions** column for the target policy.
