Backup of root UNC path not working

I am using KopiaUI 0.7.3 on Windows 10.

I have browsed to and selected the UNC path “\\server\backup” as the source. When I select “Snapshot now” the status changes to “Uploading 0 bytes” and immediately stops. I also tried with a trailing “\” - “\\server\backup\” but it does the same thing.

In the main.log it looks like it is appending “backup” to my UNC path:
[2020-12-27 19:18:40.918] [info] snapshot error: upload error: open \\server\backup\backup: The system cannot find the file specified.

If I select an individual subfolder as my source (i.e. “\\server\backup\Documents”) the backup seemingly works as expected.

Would you mind filing a bug on GitHub?

Sure, just wanted to check if there was another way to do this - I assume this should work as I have it then?

Edit: I just duplicated my share as “\\server\bkp” as a quick test and had the same issue. This time the error in the log was:

[2020-12-28 19:36:29.715] [info] snapshot error: upload error: open \\server\bkp\bkp: The system cannot find the file specified.

So it appears it is appending the share name to itself.
