Backup Service

What is Backup Service?

Backup management integrates multiple disaster recovery technologies such as incremental backup and full backup that are suitable for multiple business scenarios. You can implement local backup and remote backup based on your business needs.

Backup Service is a separate feature module. To use this service, purchase both the Base License and the Plus License of Backup Service. The Plus License cannot be used independently.

Typical Backup Scenarios

Backup Service can be applied to the following three typical scenarios: local backup, remote backup, and Public Cloud backup.
Note: If you have the Tenant Management Plus license at the same time, the project members (project managers, project admins, and general project members) can perform local backup for VM instances, elastic baremetal instances, and data volumes in the project.
  • Local Backup

    A local ImageStore image storage can act as the Local Backup Server to store scheduled backup data of the local VM instances, elastic baremetal instances, data volumes, and management node databases. Meanwhile, the seamless switchover between the primary local backup server and the secondary local backup server is supported, which effectively ensures your business continuity.

    If your local data is mistakenly deleted, or data in the local primary storage is damaged, you can recover the backup data from the local backup server, as shown in Local Backup Scenario-1

    图 1. Local Backup Scenario-1


    If you encounter a disaster in your local data center, you can rely totally on your local backup server to rebuild your data center and recover your business, as shown in Local Backup Scenario-2.

    图 2. Local Backup Scenario-2


  • Remote Backup

    A storage server in a remote data center can act as the Remote Backup Server to store the scheduled backup data of the local VM instances, elastic baremetal instances, volumes, and databases. The backup data needs to be synchronized to the remote backup server from the local backup server.

    If your local data is mistakenly deleted, or data in the local primary storage is damaged, you can recover the backup data from the remote backup server, as shown in Remote Backup Scenario-1

    If you encounter a disaster in your data center, you can rely totally on your remote backup server to rebuild your data center and recover your business, as shown in Remote Backup Scenario-2.

    图 4. Remote Backup Scenario-2


  • Public Cloud Backup
    The storage server in the Public Cloud can act as the Public Cloud Backup Server to store the scheduled backup data of the local VM instances, volumes, and databases. The backup data can be synchronized to the Public Cloud backup server from the local backup server.
    Note: The Public Cloud backup feature does not apply to elastic baremetal instances.

    If your local data is mistakenly deleted, or data in the local primary storage is damaged, you can recover the backup data from the Public Cloud backup server, as shown in Public Cloud Backup Scenario-1.

Create a Backup Job

On the main menu of ZStack Cloud, choose Platform O&M > Backup Management > Backup Service > Backup Job. Then the Backup Job page appears. On the page, choose a resource type to be backed up and click Create Backup Job. Then, the Create Backup Job page appears.

You can create the following types of backup jobs:
  • Backup jobs for VM instances/elastic baremetal instances/data volumes
  • Backup jobs for the management node database

Create Backup Job for VM Instance/Elastic Baremetal Instance/Data Volume

Follow these four steps to create a backup job for VM instances/elastic baremetal instances/volumes:
  1. Set basic information.
    • Name: Enter a name for the backup job.

      The name must be 1 to 128 characters in length and can contain Chinese characters, letters, digits, spaces, hyphens (-), underscores (_), periods (.), parenthesis (), colons (:), and plus signs (+) and cannot begin or end with spaces.

    • Description: Optional. Enter a description for the backup job.
    • Local Backup Server: Specify one or more local backup servers.
      Note:
      • You can specify up to two local backup servers for a backup job.
      • Before you can specify a local backup server, you need to add the server to ZStack Cloud Private Cloud. For more information, see Add a Local Backup Server.
      • If you specify two local backup servers, by default, the first server added to the Cloud is the primary backup server and the second is the secondary backup server.
      • If you specify two local backup servers, these two servers apply the fail-over mechanism.
        • When the primary backup server works as expected, data is backed up on the primary backup server.
        • If the primary backup server is disabled, removed, or disconnected, data is backed up on the secondary backup server.
        • When the primary backup server resumes working as expected, data backup is auto-switched to the primary backup server.
    • Sync to Remote Backup Server: Choose whether to sync local backup data to a remote backup server. By default, the checkbox is not selected.
      Note:
      • Before you can sync backup data to a remote backup server, you need to add a remote backup server to the Cloud. Note that you can add only one remote backup server to the Cloud. For more information, see Add a Remote Backup Server.
      • You can sync VM instance/data volume backup data to a server that is in another data canter or from a public cloud.
      • You can sync elastic baremetal instance backup data to a server that is in another data center.
    • Remote Backup Server: Select a remote backup server if you want to sync data to a remote server.
    • Set QoS: Optional. You can set network QoS and disk QoS for the backup job.
      • Downstream Bandwidth: Set the maximum downstream bandwidth. Unit: Kbps, Mbps, and Gbps. Valid values: 8 Kbps to 30 Gbps. If you do not specify the downstream bandwidth, this bandwidth is unlimited.
      • Upstream Bandwidth: Set the maximum upstream bandwidth. Unit: Kbps, Mbps, and Gbps. Valid values: 8 Kbps to 30 Gbps. If you do not specify the upstream bandwidth, this bandwidth is unlimited.
      • Disk Read Speed: Set the maximum read speed. Unit: MB/s and GB/s. Valid values: 1MB/s to 100GB/s. If you do not specify the disk read speed, this speed is unlimited.

The following table lists the actions that you can perform on a backup resource.
Action Description
Associate Backup Resource
Associate a VM instance with the backup job.
  • You can associate backup jobs with VM instances whose backup type is None only.
  • Before you associate a backup job, make sure that the VM instance is in the running or paused state.
  • If the authorized quota of the backup service is insufficient, no backup job can be associated.
    Note: Resources that are already within the authorized quota of the backup service can normally create backups or associate backup jobs.
Associate a volume with the backup job.
  • Volumes that already have backup jobs associated do not support this operation.
  • Before you associate a backup job, make sure that the volume is attached to a VM instance and that the VM instance is in the running or paused state.
  • Before you associate a backup job, make sure that the VM instance attached by the volume does not have a CDP task.
  • If the authorized quota of the backup service is insufficient, no backup job can be associated.
    Note: Resources that are already within the authorized quota of the backup service can normally create backups or associate backup jobs.
Disassociate Backup Resource Disassociate a VM instance/volume from the current backup job.
Enable Backup Job After you enable a backup job, the disabled VM/volume backup job that has not been performed will be added to the next backup plan.
Note: If you do not enable a disabled VM/volume backup job, the consequent backup jobs will not backup this disabled resource.
Disable Backup Job Disable the scheduled VM/volume backup job that has not been performed.
Note: When you disable a VM/volume backup job that is still in progress, the backup job will continue to run until the current VM/volume backup job is completed.
