I had some scripts running using the Windows binary on Windows 10 Pro. Since, mounting isn’t possible on Windows, I figured I would try my scripts on Windows Linux Subsystem (WLS).
Last night, while my script was humming a long, Windows 10 restarted for an update (I really need to find a way to stop this from happening). I estimate it had been running for maybe 45 minutes of the estimated 2-ish hours (which I thought was great and had me feeling optimistic). This was an initial backup to an external hard drive of less than 300GB.
When it came back, my external drive showed space being used but no files could be found on the disk. So, I reformatted it. When I was attempting to access the external drive in WLS, it was giving me an error.
I also noticed that the C drive had considerably less space. After having used WinDirStat, I noticed that WLS was taking quite a bit of space and it referred to the mount point too:
