Duplicati 2.2.0.1 - Backup aborted since the source path xxx does not exist

Hello there!

I am using Duplicati 2.2.0.1 - 2.2.0.1_stable_2025-11-09 on macOS Sonoma (14.8.1) and I am facing this error when a backup tries to backup files in my user directory /Users/foo, while being logged in as user foo:

Error while running BackupLaptop

 Backup aborted since the source path /Users/foo/.histfile does not exist. Please verify that the source path exists, or remove the source path from the backup configuration, or set the allow-missing-source option.

This file does exist and is readable by my user foo:

% ls -lh ~/.histfile
-rwx------ 1 foo staff 542K 25 nov 17:21 /Users/foo/.histfile

The full debug log is not really helpful here:

Duplicati.Library.Interface.UserInformationException: Backup aborted since the source path /Users/foo/.histfile  does not exist. Please verify that the source path exists, or remove the source path from the backup configuration, or set the allow-missing-source option.

Same behavior with other files/directory. I’ve granted Duplicati full disk access in macOs privacy settings and restarted the app, without success.

What’s the best way to troubleshoot this please?

Thanks for your help

Hi @lpkn, welcome to the forum :waving_hand:

Is there a pattern to what files/folders will cause this?

That is a good question. Duplicati will ask the OS if either a file or a folder exists, and for some reason both get a “no” back in your case.

If we can figure out some system, then maybe I can reproduce it.
