Can I backup my Synology NAS to the cloud?

"I currently run a Synology DS916+ with the DX513 expansion. I would love to back up my Synology devices to a cloud storage solution. Is it possible to get that? Which is the best cloud backup for NAS? Thanks!"

Why should you backup NAS?

NAS, namely network-attached storage, refers to storage devices that connect to a computer network and enable data access and file sharing across a heterogeneous group of clients. Synology, QNAP, Netgear, Thecus, and Asustor are leading NAS servers that are popular with people.

However, NAS is a network device, which makes data storage not absolutely secure. And when a hardware-based or software failure occurs, it may take a lot of time for data recovery. Backing up NAS to a cloud storage service not only provides double protection for your files but also allows you to quickly access and restore them should you need these documents.
