Duplicati creates a file in Google Drive destination in the connection “Test”, but doesn’t complete the backup when I press “Start”.
Here’s the log entry: “2026-02-18 23:36:52 -08 - [Error-Duplicati.Library.Main.Controller-FailedOperation]: The operation Backup has failed\r\nConstraintException: Detected 167 file(s) in FilesetEntry without corresponding FileLookup entry”
I’ve tried this several times with no success. On the prior attempts is did a partial backup the Google Drive folder, but them stopped.
This is on Windows 11.
Any suggestions would be greatly appreciated.
