Cloud Backup and Recovery

Cloud Backup and Recovery (CBR) lets you back up cloud servers, disks, and on-premises VMware virtual environments with ease. If there is a virus intrusion, accidental deletion, or software/hardware fault, data can be restored to any backup point.

  • Reliable

    CBR supports cloud server multi-disk consistency backup and database server backup, ensuring both security and reliability.

  • Efficient

    Permanent, incremental backup shortens the time required for backup by 95%. Immediate recovery, minute-level RTO.

  • Simple

    The backup configuration can be completed in just three steps, and no professional backup software skills are required. Compared with conventional backup systems, CBR is easier to use.

  • Security

    The backup data of encrypted disks is automatically encrypted to ensure data security. Backup data can be replicated across regions and restored in other regions for remote disaster recovery.


  • Ease of Use

    Policy-based automatic backup eliminates the need for complicated configuration and does not affect services.

  • Rapid Backup and Restoration

    Incremental backup and incremental restoration are supported for better efficiency.

  • Secure and Reliable Backup

    CBR ensures the data consistency of cloud server backups. Backup data can be encrypted and stored across data centers.

Ease of Use

  • In-Service Backup: You can back up a running VMware VM, cloud server, or disk without interrupting services.

  • Automatic Backup: CBR supports customized backup policies. You can define the backup cycle, execution time, and retention policies to automate future backups.

Rapid Backup and Restoration

  • Permanent Incremental Backup: A full backup is performed only for the first backup. All subsequent backups are incremental. An incremental backup backs up only the data changed since the last backup, which shortens the backup time and saves the backup space. When a backup is deleted, only the data blocks irrelevant to other backups are deleted, without affecting data restoration using other backups.

  • Instant Restoration: Based on the delayed loading technology, cloud servers and disks can be recovered immediately. Data is asynchronously loaded and the RTO is minute-level.

Secure and Reliable Backup

  • Crash-Consistent Backup: Multiple disks are backed up at the same point in time, ensuring data consistency.

  • Application-Consistent Backup: When cloud servers with databases are backed up, a backup task starts only after database transactions are completely submitted, ensuring application data is kept consistent.

  • Backup Encryption: The backup data of encrypted disks is automatically encrypted to ensure data security.
