Dual-device backup

A feature in which one device functions as a master device and the other functions as a backup device. In normal circumstances, the master device provides service access and the backup device monitors the running status of the master device. When the master device fails, the backup device switches to a master device and provides service access, ensuring service traffic continuity.

Remote Backup Profile

A configuration template that provides a unified user interface for dual-system backup configurations.

Remote Backup Service

An inter-device backup channel, used to synchronize data between two devices so that user services can smoothly switch from a faulty device to another device during a master/backup device switchover.

Redundancy User Information

A Huawei-proprietary protocol used by devices to back up user information between each other over TCP connections.
