Volume Backup Service

Volume Backup Service (VBS) backs up Elastic Volume Service (EVS) disks, and uses backups to restore EVS disks in case of disk data corruption or loss, protecting user data accuracy and security.

VBS is charged by used object storage capacity. Its backup and restoration functions are not

charged additionally. Starting from CNY 0.148/GB /month

Free-of-charge 500 GB for VIPs

Product Advantages

VBS

Conventional Disk Backup

Reliable

VBS: Stores data to object storage, with a data durability of 99.999999999%.

Conventional Disk Backup: Stores data to backup storage media, with a low reliability.

Easy to Use

VBS: Implements data backup and restoration by one click in an intuitive user interface.

Conventional Disk Backup: Uses dedicated backup software, with expertise needed for installation and configuration.

Cost Effective

ECS

Elastic Cloud Server (ECS) is a service available with ease at any time for you to build up secure, flexible, and efficient application environments, ensuring constant service continuity.

EVS

Elastic Volume Service (EVS) is a scalable virtual block storage service that is based on a distributed architecture. EVS features robust data reliability and high I/O throughput. In a similar way for traditional hard disks on servers, you can format EVS disks that are attached to ECSs, create file systems on EVS disks, and store data into them persistently.

OBS

Object Storage Service (OBS) is an object-based massive storage service that provides you with massive, low-cost, highly reliable, and secure data storage capabilities.

Application Scenarios

Hacker Attacks or Virus Infection

VBS can restore an EVS disk to the backup point in time prior to the mis-deletion.

Data Mis-deletion

VBS can restore an EVS disk to the backup point in time prior to the mis-deletion.

Application Update Errors

VBS can restore an EVS disk to the backup point in time prior to the application update.
