Product Advantages
  • 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.

Disk Backup and Restoration

Disk Backup and Restoration

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

Advantages

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 (RTO) to minutes.

Durability

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

Service Provisioning

Service Provisioning

The system disk image and data disk backup of an ECS can be used to quickly create identical ECSs, facilitating rapid batch-deployment of services across availability zones (AZs).

Advantages

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.

Functions

  • Easy and Efficient Backup

    Policies can be configured for automatic backup of EVS disks. The backups are performed without interrupting ongoing data operations on EVS disks.

  • Flexible Restoration

    Backups can be used to perform rollbacks, create disks, and incrementally restore data.

  • Data Security

    Backups can be encrypted and stored in multiple data centers.

Easy and Efficient Backup

  • 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.

  • Permanent incremental backup

    After an initial full backup, data continues to be backed up incrementally, saving backup time and space.

  • Automatic backup

    A backup policy can be easily defined and associated with one or more EVS disks to implement automatic backup.

Flexible Restoration

  • 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 the RTO down to minutes.

Data Security

  • 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.
