I have a Bluesound Node 2 as my streaming device. But, not unlike you, I was worried about backing up all my digital files I play with the Node 2. I opted for a Western Digital MyCloud 4tb NAS device. This acts as your own personal cloud (basically a HDD you own in your home) that you can save/share files through your own network. Easy to use and can backup any of your files on an additional HDD connected to the Cloud NAS. Works great and is very versatile.
Also the MyCloud is unlike a Cloud service that one pays a monthly fee to use. You own this device. And additionally, if one buys the Aurender, the digital storage is in that device not stored on an external HDD. If the Aurender crashes or becomes obsolete, your music is on the device!!!
