Overview of Network Attached Storage (NAS)

Network-attached storage, namely NAS, is literally a device that is connected to a network and has data storage capabilities. NAS is a popular business storage device by the convenience it brings to users. Users within the same LAN could connect to the same NAS and directly store or modify files without data transfer, which greatly improves work efficiency.

However, NAS storage devices also have disadvantages such as being inconvenient to expanding storage space, inadequate data protection, and being prone to hardware failures. For the sake of data security, many users want to backup from one NAS device to another. Thus, let's figure out how to do Synology NAS to NAS backup now.
