Innuos Zenith Mk3 with storage on Synology D220+
Have previously used auto-backup successfully. Last successful backup 6 days ago. Now get error message from Backup Manager: There was an error retrieving the backup listing (Invalid Root). Please check the backup folder and try again." “Find backups” shows \synology\Roon\RoodBackups but selection of that folder returns the same error message. “Backup Now” fails with message: Backup directory not available. Have re-started all hardware with same results. Help!
