I used to work for Synology so I got an employee discount. You’re paying for the software and support when you buy the NAS. Try C2 for cloud storage or just use glacier backup if you’re trying to save money.
Obviously, it's just kinda funny how many weirdos will hear about the company and immediately say "yeah well I can do it myself for cheaper!" and I'm like "ok cool have fun spending hours on that while I play video games"
