- 2-way networking The following figure shows the 2-way networking mode. In this networking mode, the backup server sends backup instructions using a local area network (LAN) to instruct the Huawei storage system to directly back up data to the connected tape library. Backup data is not sent using the LAN.
- 3-way networking (remote)
Thefollowing figure shows the 3-way networking (remote) mode. In this networkingmode, the backup server sends backup
instructions using a LAN to instruct theHuawei storage system to back up data to the tape library connected to thebackup server.
- 3-way networking (standard)
Thefollowing figure shows the 3-way networking (standard) mode. In this networkingmode, one storage device (storage B) connects to the file system to be backedup, and the other storage device (storage A) connects to the backup tape library.The backup server is connected to the two storage devices using the LAN toimplement data backup and recovery.
