  1. Created a backup destination (Add Storage) in Databasus pointing to a shared folder in an UnRaid NAS. The shared folder is called appropriately, Databasus. Backup's work as expected. Files are written to the shared folder Databasus.

  2. Due to having four databases to backup, created inside the root shared folder, Databasus, four other subfolders folders: Immich being one of them.

  3. Folder structure now is Host with the Shared Databasus folder with an Immich sub-folder underneath it.

  4. In the Add Storage we then have the following fields entered:- Name = Immich

  • Type = NAS
  • Host = IP address of NAS
  • Port = 445
  • Share = Databasus\Immich
  • Username = Specified
  • Password = Specified
  1. When Test connection is clicked, we get an error message of the IP address of the NAS followed by "failed to access share 'Databasus\Immich': mount Databasus\Immich: mount path must be a valid share name (\<share>)

  2. I can reproduce this consistently.
