What Is Volume Backup Service?

Uninterrupted backup and restoration

Volume Backup Service

Volume Backup Service performs uninterrupted backup and restoration of Elastic Volume Service disks, offering protection against virus attacks and software and hardware faults.

Volume Backup Service (VBS) provides snapshot-based data protection for Elastic Volume Service (EVS) disks in a public cloud environment.

VBS makes your data secure and reliable. For example, if an EVS disk is faulty or a logical error occurs in EVS disk data, you can use data backups to restore data quickly.

VBS supports both full and incremental backups. By default, the system first performs a full backup, and then performs incremental backups. You can use the data backups generated in either backup mode to restore EVS disks to the state they were in when the backup was created.

VBS is easy to use. You can perform one-click backup and restoration for the EVS disks on servers all through the online platform. These servers are Elastic Cloud Servers (ECSs) or Bare Metal Servers (BMSs).

Ease-of-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.

Flexibility

Backup policies can be automatically applied to cover various backup scenarios. The permanent incremental backup and restoration reduces backup time and cuts down the recovery time objective (RTO) to minutes.

Cost-Effectiveness

A full initial backup is followed by permanent incremental backups, significantly reducing the space occupied by backup files. Backup storage, which is charged based on usage, can be expanded or reduced when required.

Reliability

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.

Volume Backup Service Functions

  • Online Backup
    VBS backs up EVS disks of a running Elastic Cloud Server (ECS) and does not require the ECS's EVS disks to be detached.
  • Automatic Backup
    A backup policy can be configured by specifying the backup period, execution time, and retention rules and then associated with one or more EVS disks
  • Permanent Incremental Backup
    A full initial backup backs up only the used data space on EVS disks. Subsequent backups are incremental, backing up only the data modified since the last backup. This approach reduces the backup time and backup space. When a backup is deleted, only the data blocks exclusive to the backup are deleted.
  • EVS Disk Rollback & Creation
    An EVS disk backup can be used to restore the source EVS disk to its original state. The backup can also be used to create a new EVS disk containing the same data that the source EVS disk had when it was backed up.
  • Incremental Restoration
    When the latest backup is used to restore a source EVS disk, only the data blocks that have changed since the last backup are restored, cutting down the RTO to minutes.
  • Backup Encryption
    Backups of encrypted EVS disks are automatically encrypted to ensure data security.
  • Reliability
    Copies of each backup are stored in multiple data centers, making the backups immune to data center failures.

Volume Backup Service Application Scenarios

Disk Backup and Restoration

Online, uninterrupted backups can be performed on elastic volume service disks, and backup files can be used to seamlessly restore elastic volume service disks.

  • Ease-of-Use
    Policies can be easily defined for backing up data online.
  • Efficiency
    Permanent incremental backup restoration significantly reduces the space occupied by backup files and cuts down the recovery time objective to minutes.
  • Durability
    VBS backs up data to OBS, ensuring 99.999999999% data durability.

Service Deployment

The system disk image and data disk backup of an cloud server can be used to quickly create identical cloud servers, facilitating rapid batch-deployment of services across availability zones.

  • Ease-of-Use
    Backup can be configured in three steps and an EVS disk can be created from a backup in two steps.
  • Cost-Effectiveness
    Storage resources for backups are charged based on usage, and can be reduced when required.
  • Reliability
    EVS disk backups can be used to create EVS disks across AZs, enhancing the reliability of data.
