\data implying Docker (which I don’t use)? Is there a Duplicati-server.sqlite (server database) anywhere?
If not, do you have any Export To File of job configurations manually run and safely stashed somewhere?
Create some trivial not-to-be-run backup job and copy the job database to its not-yet-there Database path. Using Restore menu should show you what files there are, but it won’t know the original job configuration.
Separate job if you like, however here is the case for just using/testing Recreate of a job database instead.
For configuration preservation, you can backup Duplicati-server.sqlite or preserve its configuration exports.
Done how? I’m still trying to figure out if this is a Duplicati Docker, except those use /data rather than \data.
If this is Windows with a custom folder being used, what Duplicati processes do you see in Task Manager?
