So I have a few photo files. Curious what folks are using for online backup? I have a number of drives, but each is in one stage or another of getting filled up. Nice to have 5TB of data space, but Microsoft seems to not want to make this available to folks without the right op system. What that is, I dunno. I have 365Office or whatever, but they'll only make 1TB. That's piker stuff. Thoughts?
