Scenarios

DSS disk backups are created using the CBR service.

This topic describes how to configure a backup policy for a disk. With backup policies configured, data on DSS disks can be periodically backed up to improve data security.

Backups can be created for disks only when the disks are in the Available or In-use state.

Purchasing a Disk Backup Vault and Configuring the Backup Policy

1. Log in to the CBR console.
   1. Log in to the management console.
   2. Choose Storage > Cloud Backup and Recovery > Cloud Disk Backup.

2. In the upper right corner, click Buy Disk Backup Vault.
3. Select a billing mode.
   • Select the yearly/monthly mode if you have a good idea of what resources you will need during the billing period. Fees need to be paid in advance, but services will be less expensive.
   • Pay-per-use is a postpaid billing mode. Select this mode, and you will be billed based on the usage of resources. You may purchase or delete resources at any time, and fees will be deducted from the account balance.

4. (Optional) Select the disks you want to back up in the disk list. After the disks are selected, they will appear in the right area.
   Figure 1 Selecting disks
   
   

   • Only the Available or In-use disks can be selected.
   • You can associate desired disks with the vault you created later if you skip this step.

5. Specify the vault capacity. This capacity indicates the total size of the disks that you want to associate with this vault. Therefore, specify a vault capacity that is greater than or equal to the total size of the disks you want to back up. The value ranges from the total size of the disks to 10,485,760 in the unit of GB.
6. Determine whether to configure auto backup.
   • If you select Configure, you must then select an existing backup policy or create a new one. After the vault is created, the system associates the vault with this backup policy, and all disks associated with this vault will be automatically backed up according to this policy.
   • If you select Skip, disks associated with this vault are not automatically backed up.

7. If you have subscribed to the Enterprise Project Management Service (EPS), add the vault to an existing enterprise project.

   EPS provides a unified method to manage cloud resources by project, allowing you to manage resources, users, and user groups in your projects. The default project is default.

8. (Optional) Add tags for the vault.

   A tag consists of a key-value pair. Tags are used to identify, classify, and search for vaults. Vault tags are used to filter and manage vaults only. You can add up to 10 tags for a vault.

   Table 1 describes the tag parameters.

   Table 1 Parameter description

   Parameter	Description	Example Value
   Key	A tag key of a vault must be unique. You can customize the key or select the key of an existing tag created in TMS. A tag key must comply with the following rules: Contains 1 to 36 Unicode characters. Cannot be empty, cannot start or end with spaces, or contain non-printable ASCII (0-31) characters or the following special characters: =*<>\,|/	Key_0001
   Value	A tag value can be repetitive or left blank. A tag value must comply with the following rules: Contains 0 to 43 Unicode characters. Can be an empty string, cannot start or end with spaces, or contain non-printable ASCII (0-31) characters or the following special characters: =*<>\,|/	Value_0001

9. Specify the vault name.

   A name is a string of 1 to 64 characters consisting of digits, letters, underscores (_), and hyphens (-), for example, vault-612c.

   

   You can use the default name, which is in the format of vault_xxxx.

10. Specify the subscription duration if you select Yearly/Monthly for Billing Mode. The validity period ranges from 1 month to 3 years.

    Determine whether to enable auto renewal. If Auto Renewal is selected, the subscription is renewed according to the following rules:

    • Monthly subscription: Your order will be renewed each month.
    • Yearly subscription: Your order will be renewed each year.

11. Click Next. Confirm the purchase details and click Submit.
12. Pay for the order as prompted.
13. Go back to the disk backup page. The vault you created is displayed in the list.

    You can associate disks to the new vault or create backups for disks. For details, see Vault Management.
