How is Radarr & Sonarr connection working?

[alvitali]

Hi, just installed nzbdav + rclone, and the app looks extremely promising!

However, I want to integrate nzbdav into my *arr automation workflow, and I'm wondering why I have to give nzbdav access to my Sonarr / Radarr API keys. Is this step really needed?

From what I understand, nzbdav manages the activity queue in the *arrs - I'm asking because I want to create a tiered setup, with my existing torrent setup used for the core media library, while having nzbdav handle users' requests.

Is this possible, or will nzbdav interfere with downloads from torrents? Or is it better to spin up a separate instance for Sonarr / Radarr for use with nzbdav in my use case

Nzbdav acts as a downloader, like Sabnzbd say, so you don't need to give it access to the arrs. However if you want to enable automatic repairs as a consequence of the automatic background health checks finding a missing article, then you need to link your arrs. The process is something like

1. If background health checks are enabled, nzbdav continuously scans your files in the background to see if any nzb's article is missing.
2. if one is found then find the corresponding symlink /home/me/radarrrootdir/film.mkv->/mnt/nzbdav/content/film.mkv and report to radarr that the film corresponding to the file at its root dir /home/me/radarrrootdir/film.mkv needs to be deleted + searched again.

The 2nd is the part where you need to connect nzbdav->arrs.
