So I excluded any `System Volume Information` directory like this:
But when the job ran today, I got the same 3 warnings again. Am I doing something wrong?

IIRC, ending the exclude with anything other than \ or / treats the filter like a file.
If that’s correct then your rule will exclude all contents of the folder, but will still try to access the folder, thus causing the error.
I’m not where I can check, but I also think the “Exclude expression” selection automatically adds the leading dash, in which case it’s trying to exclude “anything in the folder found at dash followed by anything followed by \System Volume Information”
Try putting `-*\System Volume Information\` in the “edit as text field”.

Unfortunately, this didn’t help either. Still getting the warning.
Wait a minute, I am starting to understand what you are saying here:

You are basically saying that what you suggested will probably not work, right? Well you were right. So I have to try `*\System Volume Information\` then?
@Matthias, how exactly did you get rid of the warnings?

For example, this “Edit as text” value should exclude the a users’s “Videos” and “Downloads” folders on either Windows 98/XP (the Documents and Settings stuff) or beyond (the Users stuff): -[.:\\(Users|Documents and Settings)\\[^\\]\*\\(Videos|Downloads)\\] To use it in the regular “Exclude regular expression” field just remove the leading “-” and the surrounding “[]” so…

Good Morning,
I was asked …
@Matthias, how exactly did you get rid of the warnings?
My system:
- Notebook, Windows Operating System 10
- Standard USB Stick 32 GByte, plugged in, connected with G:\
That´s all …
Due to the case, that my USB stick is always G:\ … the Exclude Folder Option works fine.
Note: In this backup run, there was only small changes, only 10 files,
therefore the backup runs very fast …
and no warnings, errors, and the red (message) box on the screen
Regards

Adding to my last post, the result … no warnings, no errors …

Yes. In the two-field setup for “Exclude Folder”, you would put in `*\System Volume Information\` (the “-” is added automatically behind the scenes), but if you’re using the “Edit as text” option (the three dots menu just across from the “Filters” line) then you need to use `-*\System Volume Information\`.

Nope, doesn’t work. Now I was going to try
But then I thought, since I want to exclude those system volume folders globally anyway, I might aswell go for the global option `--exclude="*\System Volume Information\*"`
But those filters are confusing. So:

Doesn’t work either . 😫 It gives me:
```plaintext
Warnings: [
The supplied option --exclude is not supported and will be ignored
]
```
So, I’m wondering why the GUI accepts that option in the first place if it is not supported at the global settings level.
I also tried ` --exclude=*\System Volume Information\*` but with the same results.
I can’t believe how much time I’m spending at doing a simple thing like excluding a some folders. 😵
So now I tried this:
And it finally seems to have worked. The disadvantage is that I have to enter this for every single backup job. Why is it not possible to globally exclude stuff?

It might be worth including `\System Volume Information\` in the standard “System files” Exclude option.

This should actually work because it will not look in the folder after it has been excluded.
But `*` means “zero or more characters” so the original filter should also work.

I should fix it …

Unfortunately it is because “order matters”. As we allow both include and exclude filters, there is no sane way to simply mix two lists of filters without getting a lot of surprises.
Imagine one rule is `exclude *`, putting that first and last has two very different outcomes.
