What Is CBR?

Cloud Backup and Recovery (CBR) enables you to back up cloud servers and disks with ease. In the event of a virus attack, accidental deletion, or software or hardware fault, you can restore data to any point in the past when the data was backed up.

CBR protects your services by ensuring the security and accuracy of your data.

Data of FlexusX instances can be backed up using cloud server backup and cloud disk backup.

Cloud server backup (recommended): Use this backup method if you want to back up the data of all EVS disks (system and data disks) attached to a FlexusX instance. All disks on the instance are backed up at the same time to ensure data consistency.
Cloud disk backup: Use this backup method if you want to back up the data of one or more EVS disks (system or data disks) attached to a FlexusX instance. This minimizes backup costs on the top of data security.

For more information, see CBR Architecture, Backup Mechanism, and Backup Options.

For the differences between backups, snapshots, and images, see What Are the Differences Between Backup, Snapshot, and Image?
