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


Permanent incremental backup slashes the backup duration by 95%; incremental restoration restores only the data modified since last backup, reducing RTO to minutes.

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.


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.

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.


  • Ease-of-use

    Policies can be easily defined for backing up data online.

  • Efficiency

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

  • Durability

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

Service Provisioning

Service Provisioning (Coming Soon)

The backup of an ECS can be used to create one or more ECSs (with the same configurations as the original ECS) to batch implement service deployment.


  • Ease-of-use

    Backups can be configured and used to create ECSs in just three steps and two steps, respectively.

  • Cost-effectiveness

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

  • Durability

    Backups can be used to create ECSs across AZs.

Ease of Use

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

  • 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

Incremental backup and restoration improve efficiency.

  • 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.


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

  • 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.

  • Backup encryption

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

  • Reliability

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