Virtual Machine Backup

New Backup Plan

  • Make sure the platform has sufficient authorized backup quota.
  • Make sure the virtual machines to be backed up are in a running or paused state and are not associated with any other backup plans.
  • You cannot associate a backup plan with a virtual machine, if it uses ZHPS distributed storage.
  1. In the navigation pane, choose Data Protection > Backup Plan.

  2. On the Backup Plan page, click New Backup Plan.

  3. In the New Backup Plan dialog, complete the basic configuration and backup configuration.

  4. For Basic Configuration, set the following parameters:

    Basic Information

    • Name: Name of the backup plan.

    • Description: Description of the backup plan.

    • Data Center: Select a data center. Backup Storage

    • Local Backup Storage: Add local backup storage, with a maximum of 2 backup storage allowed for seamless failover.

    • Sync to Remote Backup Storage: Disabled by default. You can choose whether to synchronize local backup data to a remote backup storage.

      If enabled, ensure that remote backup storage has been added in advance on the platform. For more information, see Add Remote Backup Storage.

      • Remote Backup Storage: After enabling synchronization to remote backup storage, it displays the name and available capacity of the remote backup storage. Backup Object
    • Backup Object Type: Select Virtual Machine.

    • Virtual Machine: Add virtual machines that need to be backed up, and set the backup priority as needed.

      • The number of selected virtual machines must not exceed the authorized backup quota.
      • If the selected virtual machine already has backup data, creating a new backup plan will not additionally consume authorized backup quota.
      • By default, the entire VM is backed up. However, shared disks and RDM disks attached to VMs are excluded form backup.
  5. Review the configuration and click Next.

  6. For Backup Configuration, set the following parameters:

    Backup Policy

    • Backup Mode: Select default incremental backup or customized incremental backup as needed.

    • Incremental Backup Policy: Customize the incremental backup policy, including the backup cycle and execution time.

    • Full Backup Policy: When the backup mode is set to customized incremental backup, you need to customize the full backup policy, including the backup cycle and execution time.

    • Maximum Backup Chain Length: Display the length of the backup chain under the current policy, with a maximum length not exceeding 64.

    • Start Time: Set a start time for the backup plan.

    • Disk Read Speed: Set a maximum disk read speed limit. Default value: unlimited. Units: MB/s, GB/s. Range: 1MB/s to 100GB/s.

      QoS settings should match the physical network bandwidth and account for the bandwidth occupied by concurrent backups.

    For more information about backup policies, see Backup Policy.

    Retention Policy

    • Local Retention Policy: Set the local backup retention policy by quantity or time.
    • Remote Retention Policy: After enabling Sync to Remote Backup Storage, this parameter must be set. You can set the remote retention policy as permanently or by quantity or time. For more information about retention policies, see Backup Policy.
  7. Review the configuration and click OK.

After you performed backups, you can use them to restore virtual machines. For more information, see Data Recovery.
