Negative exclusion with Windows paths

Getting Help
1

Should negative exclusion work with Windows paths? If so, what is the syntax?

I’m trying to backup my G:, ignoring everything and then not ignoring specific directories:

restic backup --exclude-file .\test.exclude G:

.\test.exclude:

G:\*
!G:\file.txt
!G:\1080p

Only the root directory is included in the backup, no content. So the exclusion pattern (G:\*) works fine, but not the negative patterns. I’ve also tested with forward slashes, same result.

It should work, every exclusion pattern starting with an exclamation mark is considered to be a negative pattern. Which restic version are you using?

What output does the backup command produce if you add --verbose=2?

Turns out, negative exclusion works in a subdirectory. With the following content in test.exclude:

G:\1080p\*
!G:\1080p\O3310851.MOV
<every file / directory in G:\ root>

and using the same backup command, the O3310851.MOV is added to the repository, but none of the other files in the 1080p directory:

> restic backup -r rclone:backup:restic-test --verbose=2 --exclude-file .\test.exclude G: --tag "test" --dry-run

But I can’t get it to work in the root of the G: drive…

Can you give the following a try?

G:\?*
!G:\file.txt

But this does look like a bug. Can you open a Github issue for that?

No difference, unfortunately.
