Two steps and you're sorted. First, mount the Synology share on your Ubuntu box: install cifs-utils, create a mount point like /mnt/plex, add an fstab entry with nofail,netdev and uid=1000,gid=1000 (so the containers can write to it), then run sudo mount -a. Second, point SparkBox at it: add MEDIAROOT=/mnt/plex (no spaces or quotes) to /opt/sparkbox/.env and run sudo sparkbox up. The share then appears as /data inside the apps — Radarr's root is /data/Movies and Sonarr's is /data/TV, so match those to your existing Plex folders. Since it's a network share, imports are copies rather than hardlinks, which is exactly the copy-to-the-NAS behaviour you're after.
