Error: warnings - files not backedup/unaccessible

Duplicati works fine for backing up to mij Cloud, but for some strange ‘Warnings’ I get on the bottom of the screen of my iMac. First time there were 160 warnings, now there are 8 warnings).
The warnings say that there are problems accessing certain files:
I add an example of the warnings-text below.
I found out that for instance the folder ‘Mail’ shows a yellow triangle and seems not accessible.

My most important point is: How can I get Mail backed up?!

Thanks for some suggestions (in English, Dutch or German).

Regards

Hello, what version of MacOS are you using? What version of Duplicati?

I’m not a Mac guy but there were some discussions in the past when MacOS Catalina was in beta. Duplicati wasn’t getting the necessary rights in order to access all your data.

Hi, imuse from both the latest version. IOs BigSur, version 11.5)
I just started with Duplicati and discovered the ‘warnings’.
Thanks anyway for your reaction
Kind regards,
Johan Hahn

Ok, thanks for the additional information. Hoping another person who has Mac experience can help you out.
