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. When you want the ECS later, you can create an image from the ECS backup and use the image to create the ECS.

Backing up a server does not impact the server performance.

The backup service experiences peak usage between 22:00 and 08:00, during which delays may occur. To ensure optimal performance, it is recommended that you evaluate your service types and stagger backups across discrete time periods.

Prerequisites

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

Procedure

Log in to the CBR console.
1. Log in to the CBR console.
2. In the upper left corner, click and select a region.
3. Click and choose Storage > Cloud Backup and Recovery.
On the Cloud Server Backups page, click the Vaults tab and find the vault to which the server is associated.
Perform backup in either of the following ways:
- Click 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.
- Click the vault name to go to the vault details page. On the Associated Servers tab, locate the target server and click Perform Backup in the Operation column.

Set Name and Description for the backup.

**Table 1** Parameter description
Parameter	Description	Remarks
Name	Name of the backup you are creating. NOTE: You can also use the default name 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.	--

Choose whether to enable full backup. If full backup is enabled, CBR performs a full backup on every associated server. A full backup requires a larger capacity than an incremental backup.
Click OK. CBR automatically creates a backup for the server.

On the Backups tab, if the status of the backup is Available, the backup task is successful.
- A server can be restarted if the backup progress exceeds 10%. However, to ensure data integrity, 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. For details, see Restoring from a Cloud Server Backup and Creating an Image from a Cloud Server Backup.
