Cloud Server Backup Service

Easy Backup for your virtual device

Flexible Engine / Computing


Cloud Server Backup Service(CSBS) offers the backup protection service for Elastic Cloud Servers (ECSs). It works based on the consistent snapshot technology for Elastic Volume Service (EVS) disks. It enhances data security with crash-consistent backups. Backups of all the EVS disks on an ECS are generated at the same point in time; however, applications and file systems on the ECS are not suspended before backup, and memory data is not backed up. With CSBS, you can use backup data to restore ECS data.


Easy with self-help

CSBS has a visual user interface for tenants to apply for and use CSBS as well as backup and restore data.

Reliable and efficient

CSBS stores data to object storage, which delivers a durability of 99.999999999%.


CSBS leverages permanent incremental backup to save storage space. In addition, it supports on-demand space allocation and elastic space scaling to reduce initial investment.


Application scenario: 

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.

 CSBS applies to the following scenarios:

  • Hacker attacks and virus infection : CSBS can restore an ECS to the latest backup point in time when the ECS has not been affected by hacker attacks and virus.
  • Mis-deletion : CSBS can restore an ECS to the backup point in time prior to the mis-deletion.
  • Application update errors : CSBS can restore an ECS to the backup point in time prior to the application update.
