Duplicati is a nice backup tool that is cross platform. However sometimes it has issues. This post gives one solution for dealing with the error “Unexpected difference in fileset version”.
- Open the duplicati web page
- Pay attention to the fileset version number in the error message.
- Dismiss the error
- Click on the troubled backup
- Click on commandline
- Change the command at the top to delete
- Clear out the commandline arguments field
- Put “–version=XX” in the commandline arguments field (change XX to version specified in the error message)
- Click Run “delete” command now at the bottom right
- Wait
- Execute a new backup and see if there are errors
- Repeat if necessary
