Overview

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 and volumes in the project.
  • Local Backup

    A local ImageStore backup storage can act as the Local Backup Storage to store scheduled backup data of the local VM instances, volumes, and management node databases. Meanwhile, the seamless switchover between the primary local backup storage and the secondary local backup storage 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 storage, as shown in Local Backup Scenario-1

    Figure 1. Local Backup Scenario-1


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

  • Remote Backup

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

    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 storage, as shown in Remote Backup Scenario-1

    Figure 3. Remote Backup Scenario-1


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

  • Public Cloud Backup

    The storage server in the Public Cloud can act as the Public Cloud Backup Storage 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 storage from the local backup storage.

    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 storage, as shown in Public Cloud Backup Scenario-1.

    Figure 5. Public Cloud Backup Scenario-1


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