My backups have started failing now with the last successful one on 14 Jan. Very simple setup with RoonCore running on my Windows 10 machine. Tried various backup locations but fails after a few minutes snapshotting databases. Any ideas?
That happened to me backing up Nucleus to attached USB drive. I ended up reformatting the USB drive to exFAT and starting over with backups. No problems since.
Sorry for the late reply. I looked at the logs and deleted a couple of files which Roon had flagged as corrupt (even though they played perfectly well in other apps). The backup seems to have then completed successfully.
