Thanks JonMikeIV for following-up and for providing the link. Eventually, I suspected that it might actually have been the same as the issue I experienced in this other thread when actually trying to do a back-up: Backup run through web interface does not work, but works through exported command line
I had gotten past the recreating database step by running the re-create via the command line, hoping it was just a one-off issue due to me migrating from Linux to Windows.
I never came back to try to figure out where the recreating database hung, but I suspect it was the same issue (the OneDrive backend class being blocked on a Console.WriteLine statement). This was on version release/2.0.3.3_beta.
I’ve actually since switched to just building the latest version off of the master branch so I could use the new OneDriveV2 backend, which it is working great so far!
