And also today, I apologize for my bad english.
The context comes from DeepL
Remember, if anyone answers me.
Today I selected “Add Backup” via the WebGUI.
The target is a network hard disk, it is LUKS encrypted and has an ext4 file system. I access it via SSH and create the backup using Duplicati PGP encryption
I do this from the same computer to the same target with the same method since a long time with different data. But with the new directories that are to be backed up with this method, the error message appears as in the subject.
Unfortunately I can’t see which data is causing the error, because the backup starts first and backs up a large part of data before the error occurs.
You might have to try backing up your area adding a bit at a time until you can locate the bad name.
Another option would be to set up a log-file at log-file-log-level=verbose and search with a good tool.
Possibly you will need one that will let you find lines ending with a space or period. Finding folders is simpler because Duplicati logs folders with backslash at the end. Below is a test set of odd folders:
