Create disk backups

Precautions

You cannot use the disk backup feature to back up or restore local disks. For more information, see Local disks.

If you use local disks to store data, your data may be lost. We recommend that you use the ECS file backup feature to protect your files in local disks and use the database backup feature to protect your databases deployed in local disks. For more information, see Back up files from ECS instances and Database backup.

Procedure

1. Log on to the HBR console.
2. In the left-side navigation pane, choose Backup > Disk Backup.
3. In the top navigation bar, select a region.
4. In the upper-right corner of the Disk Backup page, click Disk Backup Wizard.
5. In the Disk Backup Wizard panel, select the disk that you want to back up and click Next.
6. In the Configure Backup Policy step, set the Backup Type parameter to Manual Backup or Auto Backup.
   • Manual Backup

     If Manual Backup is specified, you must enter the name of the backup file in the Backup Name field.

     The name must be 2 to 128 characters in length, and can contain only the following special characters: periods (.), underscores (_), hyphens (-), and colons (:). The name cannot start with auto, a special character, or a digit.

   • Auto Backup

     If Auto Backup is specified, you can select a backup policy from the drop-down list. You can also click Create Backup Policy and set the parameters to create an automatic backup policy. The following table describes the parameters.

     Parameter	Description
     Policy Name	The name of the custom policy.
     Backup Time	The time at which you want to run a backup job.
     Backup Week	One or more days on which you want to run backup jobs in a week.

     Replication to Other Region	If you enable the cross-region replication feature, the backup files that are created by the backup plan are automatically replicated to a specified destination region. Backup files can be replicated between the China (Hong Kong) and Singapore (Singapore) regions. If the ECS instance is infected with viruses or data is lost due to accidental deletion, you can use backup files in the source region or backup files replicated to the destination region to create an instance or a disk to restore data. Valid values: Enabled Not Enabled
     Destination Region	You must specify a value for this parameter only if the Replication to Other Region parameter is set to Enabled. The destination region to which you want to replicate the backup files.
     Replicated Backup Point Retention Period	You must specify a value for this parameter only if the Replication to Other Region parameter is set to Enabled. The period of time for which you want to retain the backup files that are replicated to the destination region. Custom: You can specify a retention period. Valid values: 1 to 65536. Unit: days.
