Network Attached Storage (NAS) devices are typically used for local file storage, but the introduction of remote access features has significantly enhanced their utility. Remote access allows users to retrieve files, photos, and videos from anywhere, effectively replacing certain cloud services. For instance, the UGREEN NAS utilizes a feature called UGREENlink, enabling users to connect to their NAS over the internet without complex configurations like port forwarding. This functionality is mirrored in other NAS systems, such as Synology's QuickConnect and QNAP's myQNAPcloud, which streamline remote access and file sharing. Additionally, while most NAS operating systems now include built-in remote access, tools like Tailscale are necessary for accessing self-hosted applications not supported by the NAS's native software. Tailscale simplifies the process by allowing users to connect devices to a private network without extensive setup, making it easier to manage various applications hosted on the NAS. Overall, remote access transforms the way users interact with their NAS, making it a powerful alternative to traditional cloud storage solutions.
