I am using the latest Linux Mint and included rclone v1.50.2.
I did the plain vanilla install for OneDrive, ran the command
"rclone --vfs-cache-mode writes mount "onedrive": ~/OneDrive "
and got the expected result of mounting the drive in my OneDrive directory. I have a Calibre ebook library as the only data, and found that it was pretty slow. I only make small changes every few days, and when using Dropbox with their Linux app, I would just use rsync to update the dropbox directory. So I decided to try using "rclone sync" to update a static directory instead of mounting it. I exited from the mount command, and didn't run it again, and used the sync command which seemed to work fine.
OK, so then I thought I'd try mounting it again, to to do some more experimenting, so I started with an empty directory, ran the mount command, and most of the files showed up, but not quite all of them. Calibre complained about the database, so I compared the directory and found one of the missing folders on the mounted drive, and then went to the OneDrive website to see if it was missing there, as I know everything was right previously.
On the website, the file list was refreshing, and very hard to scroll. I disabled the mount command, in case it was causing problems. But it seemed to be missing a lot of files on the website, and after about 15 minutes, they were all gone.
I never deleted files on either the client or the server during this time. I can't imagine what caused all the files to start getting deleted. I didn't have any other computers running at the time, and nobody else would have been connected, I don't think - I have two-factor authorization enabled for the account.
So, my basic question is:
What would cause the remote files to start getting deleted? Is there any sort of background process running (by default) that I might not know about?
