Burnable discs are generally not good for archival storage unless the more expensive archival quality discs are purchased. The only thing worse than a backup is thinking you have a good backup and finding it is unusable when you really need it.
Full disclosure, we are an Apple iPhone and Macintosh laptop home. But I came across this: I once owned a DOS-based, PC luggable, but had to give it up due to high blood pressure. I remain convinced my last employer insisted I use a Windows system in the hope of making me stroke-out. Bob Wilson
WD My cloud, it is a personal cloud. Accessible anywhere, but still in your home if you wish and it can automatically back up if your settings are correct. It is usable for both Mac and Windows. My son also has one. One of the nice things is you can set up safe points on another WD Cloud so your secondary backup is stored off site. (my son's for me) I have a 2T and it's used for 2 computers. If your computer memory gets full, Transfer and keep your movies, photos, music, etc., to the "My Cloud". It's been working great for 4 years now, need it once 2 years to reset 1 computer. Still room for a safe point for my son's computer.
Judging on old hardware and software is nonsense. My house uses very up to date hardware and software. UPS systems. Our reactions to Windows 10 would go like this: 1. Me: No crashes or problems in so many years I can't recall when they might have been. Certainly not on Windows 10. Only problem I can recall was a mouse that physically wore out from constant use over many years. I update regularly, manually back up to a series of flash drives which I have tested by using them to transfer files to a new computer and NT version. I have files going back decades. My first use of a computer was 50 years plus ago. I worked in OS modification, support and design. Managed a data center. Used NT when it was in Alfa status. Have the t shirt to prove it. Ditto Windows when it was 31 floppies loaded onto a 286 in about 24 hours. 2. My son: No problems I can remember other than a desire for more current hardware in the last dozen years. Network savvy. Grew up using computers. Uses the computer mostly as an internet portal. Backs up to a flash drive. 3. My wife: She hates all computers. At least once a day hands me her phone or computer with a "what do I do now" question. She would ask "what is a backup". I do it for her. She would be the one with the negative responses. She equates the computer to what is on her screen and doesn't understand internet plumbing, the cloud or web site issues.
