Have you tested it on cloud drives like s3?
It should include some testcases.

I was going to look into your current test cases as I would assume this is already tested using s3, but I didn't find any? I see a test for the public disk and that test is still green.
Also its only the local part that has changed. Anything cloudbased is unaltered :)

Thanks for your PR. But if you want to change some source code, you should provide a full maintenance for it with working guarantee in all edge cases (with appropriate test cases).
