# Creating a Cloud Server Backup

This section describes how to quickly create a cloud server backup.

If you do not need an ECS for the moment, you can back up the ECS and then delete it. Then, create an image from the ECS backup and use the image to create an ECS as needed.

During the cloud server backup, the performance of the server is not affected. To ensure data integrity, back up the server during off-peak hours when no write operation is performed on the disks.

#### Prerequisites

- Only servers in the Running or Stopped state can be backed up.
- At least one server backup vault is available.

#### Procedure

1. Log in to CBR Console.

   1. Log in to the management console.
   2. Click in the upper left corner and select your region and project.
   3. Choose Storage > Cloud Backup and Recovery. Select a backup tab from the left navigation pane.
2. On the Cloud Server Backup page, click the Vaults tab and find the vault to which the server is associated.
3. Choose More > Perform Backup in the Operation column. In the server list, select the server you want to back up. After a server is selected, it is added to the list of selected servers. See Figure 1.

4. Set the Name and Description for the backup. Table 1 describes the parameters.

   Table 1 Parameter description
   Parameter | Description | Remarks
   --- | --- | ---
   Name | Name of the backup you are creating. A name must contain 1 to 64 characters including digits, letters, underscores (_), or hyphens (-). NOTE: You can use the default name, which is in the format of manualbk_xxxx. If multiple servers are to be backed up, the system automatically adds suffixes to their backup names, for example, backup-0001 and backup-0002. | manualbk_d819
   Description | Description of the backup. It cannot exceed 255 characters. | --

5. Choose whether to enable full backup. If full backup is enabled, the system performs a full backup on every associated server, which requires a larger capacity compared to an incremental backup. See Figure 2.

6. (Optional) You can also click the vault name to open the detailed page of the vault. On the Associated Servers tab page, locate the target server. Click Perform Backup in the Operation column of the server. See Figure 3.

   Figure 3 Perform Backup

7. Click Yes. The system automatically creates a backup for the server.

   On the Backups tab page of the Cloud Server Backup page, if the status of the backup is Available, the backup task is successful.

   You can restart a server if necessary after the backup progress exceeds 10%. However, to ensure data integrity, you are advised to restart it after the backup is complete.

   After the backup is complete, you can use the backup to restore server data or create an image on the Cloud Server Backup homepage. For details, see Restoring Data Using a Cloud Server Backup and Using a Backup to Create an Image.
