Every I/O operation is recorded without any data loss. Therefore, VM data restoration can be performed from any I/O log record point with an RPO of 5s/1s (configurable).
The CDP function is independent of the VM QEMU business and uses an asynchronous caching mechanism. The I/O copy process has essentially no impact on business performance and no impact on business stability.
Multi-disk data consistency check is provided for VMs to ensure the integrity and reliability of backup data.
During the startup of a VM, CDP can be enabled for business operations before CDP data sync is completed. The VM I/O data backup is also performed.
The CDP function supports quick browsing and retrieval of backup files, making it easier for users to quickly obtain data files from the CDP backups. Detailed audit logs and permission control are also provided to ensure the security of this function.
It is integrated into HCI and delivered together for operation on VMs, which eliminates the need to install third-party software or plugins.
CDP is flexible in use. CDP can be enabled on specified VMs and can be enabled or disabled dynamically in HCI. For example, the CDP function can be enabled on a running VM without restarting or interrupting business operations.
The CDP function is easy to use and has no learning curve. It facilitates stable and reliable IT innovation for customers.
