Nice job.

I'm a little skeptical though -- I think the devil is in the details. It's a lot of work to make a highly reliable backup program. As a Windows user, here's a list of questions I'd ask:

1. Does Relica work with OneDrive on-demand files? [1]

2. Does Relica work with WSL files? [2]

Supporting all these corner cases on Windows, Mac, and Linux will be a TON of work.

Thanks for bringing up the hard questions. We have not yet made special considerations for OneDrive on-demand files or WSL files. Indeed, they require a lot of work. (I've been learning that, I think, Windows has a lot more edge cases than Linux does, in general... Windows has definitely been more difficult to develop for.)

So yeah, it's a lot of work. I know that there are major performance and correctness issues when dealing with OneDrive mounted storage and the equivalent for other sync services. Still, I've added your feedback to our list. Thanks!

What's your expectation with OneDrive on-demand files?

For any files, my expectation of a backup program is that Restore(Backup(FS)) == FS, where FS is the state of my file system.
