I'm in IT and have fucked around with various NASs and different RAID setups for decades. What will annoy my fellow nerds, but is an absolute truth, is that Amazon photos, which is 'free' with Prime is a far, far better solution in terms of convenience, usability and reliability than anything else I've been doing. We've tens of thousands of photos synched to it and, not only that, we actually go back and look at these memories frequently as it's setup as a screen saver on our firesticks and other devices. We've literally watched a movie as a family and then spent half an hour after watching the picture slideshows that come up. Other than being part of the Amazon ecosystem which I know will garner righteous hatred (and perhaps rightly), I genuinely can't fault it and sleep easy knowing that my stuff is safe.
