Welcome to the forum @rosser

Please clarify how you are specifying X:\log and what permission checks X: drive has. Depending on what user Duplicati is run as (clarify), Windows may certainly deny access.

EDIT 1:

I’m seeing some suggestions that you used log-file or similar in the GUI Commandline.
If you’re not sure what user Duplicati got run as, check Username in About → System info.

Here’s the English translation of the Chinese text:

Duplicati is running as the **local administrator user: rnas. Even after I granted Everyone full control permissions, access is still denied. In fact, no matter what path I provide, access is denied

You didn’t answer my first question, but if you’re saying log-file=C:\log that will fail.

fails for me because C:\tmp is a folder, so Duplicati can’t write to it. Give it a file to log to.

If I guess wrong at what you did, please say what you did.

Here’s the English translation:

“I thought --log-file=<path> was a folder path. How should I use it?”

Here’s the English translation:

"I have successfully specified the .log file, but encountered the following error:

It’s not. It’s a file path. Please specify a file to log to. Which you did I guess, so up next:

On Source screen. you added filters. This is fine for backup but not list-broken-files.

Filters go in the Commandline as --exclude and maybe --include. Delete them there.
