Creating a Disk Backup

Updated on 2024-09-25 GMT+08:00

Scenarios

This section describes how to quickly purchase a disk backup vault and perform backup.

If the disk to be backed up is encrypted, the backup will also be automatically encrypted. The encryption attribute of backups cannot be changed.

Operation Process

Table 1 Operation process of creating a disk backup

Step

Description

Making preparations

Register with Huawei Cloud, complete real-name authentication, top up your account, and create an IMA user.

Purchasing a disk backup vault

Purchase a disk backup vault to store disk backups.

Associating disks

Associate your disks with a vault to back up and replicate data.

Creating a disk backup

Create disk backups to protect data.

Making Preparations

  1. Sign up forHuawei Cloud.
  2. Top up your account.

Purchasing a Disk Backup Vault

Before backing up data, you need to purchase a disk backup vault.

  1. Go to the Buy Disk Backup Vault page.
  2. Set mandatory parameters for the disk backup vault based on the parameter description table. For parameters not included in this table, retain the default values.

    Configure Basic Settings, Resources to Back Up, and Backup Capacity.

    Parameter

    Example Value

    Description

    Billing Mode

    Pay-per-use

    • Yearly/monthly is a prepaid billing mode. You are billed based on the subscription duration you specify. This mode is ideal when the resource use duration is predictable. A longer subscription often means a lower cost.
    • Pay-per-use is a postpaid billing mode. You are billed based on your resource usage and you can increase or delete resources anytime. Fees are deducted from your account balance.

    Region

    CN-Hong Kong

    Resources in different regions cannot communicate with each other over an intranet. Select the region closest to you to enjoy low latency.

    Resources to Back Up

    Skip

    • Configure: Select the disks to be associated.
    • Skip: If no disk is available, you can purchase the vault first and associate disks later.

    Backup Capacity

    100 GB

    Specify the vault capacity. The capacity ranges from 10 GB to 10485760 GB.

    This capacity indicates the total size of the disks that you want to associate with this vault. Properly plan the vault capacity, which must be at least the same as the size of the disks you want to back up.

    As the vault's used space grows, you can expand the vault capacity if it becomes insufficient.

    Configure Backup Policy, Enterprise Project and Advanced Settings.

    Parameter

    Example Value

    Description

    Auto Backup

    Skip

    • Configure: A backup policy can be applied to this vault. Resources associated with this vault will be automatically backed up based on the policy. You can select an existing backup policy or create a new one.
    • Skip: Resources associated with this vault will not be automatically backed up until you apply a backup policy to the vault. If you need to automatically back up data periodically, you can create a policy and apply it to the vault. For details, see Policy Management.

    Automatic Association

    Skip

    • If you select Configure, in the next backup period, CBR will automatically scan all unprotected servers, associate them with the vault, and then perform backups.
    • If you select Skip and need to enable automatic association later, see Associating Resources to a Vault.

    Enterprise Project

    default

    Add the vault to an existing enterprise project.

    This parameter is displayed only for enterprise users who have enabled enterprise project management.

    NOTE:

    If the CBR FullAccess permissions have been assigned to IAM users, enterprise projects will not be displayed for you to choose from when you create a vault. Go to the Enterprise Project Management console and assign the CBR FullAccess permissions to the target user group.

    Vault Name

    vault-6fa8

    Specify a name for the vault.

    A name must contain 1 to 64 characters including digits, letters, underscores (_), or hyphens (-). You can also use the default name vault_xxxx.

  3. Click Next.
  4. Click Submit. Confirm the order details and complete the payment.
  5. Go back to the Cloud Disk Backups page. You can see the created vault in the vault list.

Associating Disks with the Vault

The selected servers must have not been associated with any vault and must be in the Running or Stopped state.

If you have associated disks when purchasing a vault, skip this step.

Prerequisites

  • The selected disks must have not been associated with any vault and must be in the Available or In-use state.

Procedure

  1. On the Cloud Disk Backus page, locate the target vault and click Associate Disk in the Operation column.
  2. In the resource list, select the resources you want to associate with the vault. After resources are selected, they are added to the list of selected resources.

  3. Click OK. Then on the Associated Disks tab page, you can view resources that have been associated.

For details about automatic association, see Associating Resources to a Vault.

Creating a Disk Backup

After resources are associated, CBR will automatically back up your data, or you can back up data manually. Only servers in the Running or Stopped state can be backed up.

Backing up a server does not impact the disk 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

A disk can be backed up only when its status is Available or In-use. If you have performed operations such as expanding, attaching, detaching, or deleting a disk, refresh the page first to ensure that the operation is complete and then determine whether to back up the disk.

Procedure

  1. On the Cloud Disk Backups page, click the Vaults tab and find the vault to which the disk is associated.
  2. Click Perform Backup in the Operation column. In the disk list, select the disk you want to back up. After a disk is selected, it is added to the list of selected disks.

    NOTE:

    CBR will identify whether the selected disk is encrypted. If it is encrypted, the backups will be automatically encrypted.

  3. Set Name and Description for the backup.

    Parameter

    Description

    Example Value

    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 disks 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.

    --

  4. Choose whether to enable full backup. If full backup is enabled, CBR performs a full backup on every associated disk, which requires a larger capacity compared to an incremental backup.

    NOTE:

    By default, the first backup is a full backup, and subsequent backups are incremental backups.

    To ensure data security, when you perform manual backups, a full backup is performed after 100 incremental backups by default.

    For details, see What Are Full Backup and Incremental Backup?

  5. Click OK. CBR automatically creates a backup for the disk.

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

    NOTE:

    If you delete data from the disk during the backup, the deleted data may fail to be backed up. To ensure data integrity, delete the target data after the backup is complete, and then perform the backup.
