seems the problem from External USB HDD - setting for alternate-target-paths + alternate-destination-marker have no effect - Support - Duplicati
is back in Duplicati 2.1.2.3_beta_2025-10-11
These are the options i have set in the job
alternate-destination-marker=backupdisk02.tag
alternate-target-paths=*/duplicati
or this
alternate-destination-marker=backupdisk02.tag
alternate-target-paths=*:/duplicati
or this
alternate-destination-marker=backupdisk02.tag
alternate-target-paths=*:\duplicati
This is the error i am getting
“2025-10-22 10:50:07 +02 - [Error-Duplicati.Library.Main.Controller-FailedOperation]: The operation Backup has failed\nUserInformationException: The marker file \”_backupdisk02.tag\" was not found in any of the examined destinations: /, *, \\duplicati"
