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.

$0.046 USD/GB-month

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 time needed for backup by 95%; incremental restoration restores only the data modified since last backup, reducing RTO down to minutes.

  • Easy to Use

    Backup can be configured in three easy steps and does not require elaborate planning. Adding to the appeal, 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.

  • 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 quickly restore data, ensuring service security and reliability, while saving 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 (Coming Soon)

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.


Backups can be used to create ECSs across AZs.

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 any interruption to services.

  • Automatic backup

    A backup policy can be easily defined and associated with one or more ECSs to achieve 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

    Backups are sliced and stored in multiple data centers, preventing failures at the data center level.

  • Backup encryption

    Backups of encrypted disks are automatically encrypted, helping ensure a higher level in data security.
