tbh not all people can run their own infrastructure (let alone manage/maintain it). I'm not sure about you but most non-techie people I know rely on online services to keep their data safe. some (maybe) have a USB drive to keep a copy.
talking about the setup I'm a bit more flexible in some regards to save bandwidth
Cloud/data storage/services
XCP-NG + NextCloud + 3TB NAS (24/7) -local
mail server+ Dynamic DNS on VPS (for mail - local sync)-online
a few small VM's for various services-local
Archiving/Backup:
40TB archive NAS for daily backups of all stuff that I keep online+offline including phones,tablets, etc
Video/Audio content:
local private copies + shared though youtube (as alternatives for content blocked on youtube I use RuTube or Youku)
Edit: Forgot about the off-site backup (different country 40TB NAS as offsite mirror)
I noticed a lots of people are doing this after they got a NAS. I think there is a business opportunity: NAS vendors can turn their NAS service to a platform that allows it's users to rent "apps" from the platform by paying a small amount of money every month or year. Most of the money goes to the app developers to support their development. When the developer updates the app, the NAS will then automatically download and apply the update.
There is no vendor lock-in as long as the user has the root control of the NAS device (Or at least get their data out of the machine). If the user decided to switch to another NAS vendor, they can simply migrate the data to the new machine.
