Unable to start the purge process as there are 222 orphan file(s)

I have filled up the disk of my remote backup-server. It is a cli-backup from a ubuntu-server without GUI.
Must have made a mistake when excluding symlink to an iso-file.

When I try to purge that iso-file from the backup-set, the “duplicati-cli purge”-command fails with
ErrorID: CannotPurgeWithOrphans
Unable to start the purge process as there are 222 orphan file(s)

How do I erase those 222 orphan files ?

Welcome to the forum @mortenchristensen

This (according to Google search) is a very rare issue, so there’s not much known about it, but maybe

So I guess I guessed right in that case. Probably best to save as much as possible, e.g. local database which should be easy, and maybe even destination files if it’s possible and backup is critically important although I’m not really super worried about accidental damage to destination. There’s just no guarantee.

So what are orphan files? and how to solve their existence issue? was an earlier round of guess and fix:

and this should not be able to harm destination files, so no need to worry about that. To get back to prior database problem, just put back the copy of the database you saved, and you can try something else…
