Cloud Server Backup Service

Cloud Server Backup Service (CSBS) backs up Elastic Volume Service (EVS) disks consistently on Elastic Cloud Servers (ECSs) without interrupting services. Leveraging state-of-the-art protection from virus attacks and software and hardware faults, CSBS allows you to restore data from any backup point in time.


Product Advantages
  • Reliable

    CSBS backs up all EVS disks at the same point in time, removing any potential inconsistencies in your data.

  • Efficient

    Permanent incremental backup slashes the backup duration by 95%; instant restoration, reducing RTO to seconds.

  • Easy to Use

    Backup can be configured in three easy steps and does not require elaborate planning. In addition, the storage space on backup servers can be easily expanded when required.

  • Secure

    Backups of encrypted disks are also encrypted, ensuring multiple levels of security. Backup data is stored in multiple data centers, ensuring 99.999999999% data durability.

Application Scenarios
  • Data Backup and Restoration

  • Service Provisioning

Data Backup and Restoration

Data Backup and Restoration

Consistent backup is performed on all EVS disks on an ECS so backups can be used to fast restore data, ensuring service security and reliability, and saving your time and effort.



Policies can be easily defined for backing up data online.


Incremental backup reduces backup time and incremental restoration cuts down RTO to minutes.


CSBS backs up data to OBS, ensuring 99.999999999% data durability.

Service Provisioning

Service Provisioning

You can use the image of an ECS's backup to create an ECS with the same configurations as the original ECS to realize fast service deployment.



You can replicate your ECSs in three easy steps.


Backup storage resources are purchased on demand and charged on a pay-per-use basis.


You can create ESCs across AZs, meeting a variety of reliability requirements.

Related Services




  • Ease of Use

    Policy-driven online backup simplifies configuration and has no adverse impact on services.

  • Efficient Backup and Restoration

    Incremental backup and restoration improve efficiency.

  • Reliability

    CSBS ensures data consistency, encrypts backup data, and stores backups across data centers.

Ease of Use

  • Online backup

    Running ECSs can be backed up online, without interrupting services.

  • Automatic backup

    A backup policy can be easily defined and associated with one or more ECSs for automatic backup.

Efficient Backup and Restoration

  • Permanent incremental backup

    After an initial full backup, data continues to be backed up incrementally, saving backup time and space.

  • Incremental restoration

    The latest backup is used for restoration. Only data changed since the last backup is restored, reducing RTO to minutes.


  • Crash-consistent backup

    EVS disks on an ECS are backed up at the same point in time without freezing applications and file systems. Memory data is not backed up during this process.

  • Reliability

    A backup is sliced and is stored in multiple data centers, preventing failures at the data center level.

  • Backup encryption

    Backups of encrypted disks are automatically encrypted, ensuring data security.
