Creating a Cloud Server Backup

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

The backup process for BMSs is the same as that for ECSs.

If you do not need an ECS for the moment, you can back up the ECS and then delete it. When you want an ECS later, you can create an image from the ECS backup and use the image to create ECSs.

Backing up a server does not impact the server performance.

Peak hours of the backup service are from 22:00 to 08:00, during which there may be delays. So you are advised to evaluate your service types and schedule backups in 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 management console.
2. Click in the upper left corner and select a region.
3. Click and choose Storage > Cloud Backup and Recovery. Select a backup type from the left navigation pane.
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:
- 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.
- Click the vault name to go to the vault details page. On the Associated Servers tab page, locate the target server and click Perform Backup in the Operation column.

Set 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 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, which requires a larger capacity compared to an incremental backup. See Figure 1.

Figure 1 Full Backup
Click OK. CBR automatically creates a backup for the server.

On the Backups tab page, 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.
