How to Sync 2 Radarr or Sonarr with each other⧫

In this guide I will try to explain how you can sync two (or more) Radarr/Sonarr instances with each other.

I’m going to show two different options on how you can setup your sync with two Radarr/Sonarr instances.

  • Option 1: This option is best used if you want a 1:1 copy of your Radarr/Sonarr instances as it’ll sync everything.
  • Option 2: This option is best used if you only want to cherry pick which Movies/TV Shows you want as 4K/2160p (UHD).

I’m not going to explain how to set up two Radarr/Sonarr instances for your system, being it depends on how you have it installed/running. Radarr Multiple Instance Information and Sonarr Multiple Instance Information

Preparation⧫

For this you need to have prepared the following:

  • Two Radarr/Sonarr instances fully setup (Indexers, Custom Formats, Downloaders, etc).
  • One download client (Two if you prefer Usenet and Torrents).
  • Your download client has two separate categories (movies-hd, movies-uhd, tv-hd, tv-uhd, etc)

Warning

‼You can’t use the same root (media library) folder for both Radarr’s/Sonarr’s‼

Make sure you use two separate root folders in Radarr/Sonarr (movies-hd, movies-uhd, tv-hd, tv-uhd, etc)

Option 1⧫

In this example I’m going to use two Radarr instances (The basics is the same for Sonarr).

  • Radarr 1 = My main 4K/2160p (UHD) Radarr.
  • Radarr 2 = My 1080p Radarr that I’ve setup for a streaming optimized quality profile.1

This option is best used if you want a 1:1 copy of your Radarr/Sonarr instances

Adding the Radarr Sync list⧫

In Radarr 2 go to Settings => Lists

Radarr Settings Lists

Click on the + to add a list and select Radarr

Radarr add List

Then you get a screen with the following options:

Radarr Add Lists Options

  1. The name you want to call your Sync list.
  2. Enable to Enable the list.
  3. Enable so the movies will be automatically added.
  4. Enable so the movies will be added and monitored (if disabled then there will be no search done for the movies).
  5. Enable so Radarr will perform a search when a movie is added.
  6. When Radarr shall consider a movie as available.2
  7. The Quality Profile you want to use on Radarr 2.
  8. Your root location for your media library.
  9. The Full URL to Radarr 1 (Use local URL if they run on the same system).
  10. Your API Key of Radarr 1.
  11. Which Profile of Radarr 1 you want to Sync with Radarr 2.
  12. Test the connection to Radarr 1.
  13. Save your settings.

Radarr Download client setup⧫

You don’t need a separate download client for your two Radarr instances, this all can be done with one download client (Two if you prefer Usenet and Torrents).

Settings => Download Clients

!Radarr - Settings Download Clients

Select your preferred download client.

!Radarr - Settings Download Clients Categories

The only thing you need to change/create is a separate Category that you’re going to use for Radarr 2

Warning

This can’t and shouldn’t be the same category you use for Radarr 1 but a separate Category.

How does this Radarr Sync work⧫

You now only need to make use of Radarr 1. All movies you add to Radarr 1 will be synced to Radarr 2 at a scheduled time.

Option 2⧫

In this example I’m going to use two Sonarr instances (The basics is the same for Radarr).

  • Sonarr 1 = My main 1080p WEB-DL Sonarr.
  • Sonarr 2 = 4K/2160p (UHD) WEB-DL Sonarr.

This option is best used if you only want to have a few TV shows (or movies if you use this option with Radarr) as 4K/2160p (UHD)

In Sonarr 1 go to Settings => Profiles

!Sonarr - Settings - Profiles

  1. If you’re interested in the 1080p streaming optimized quality profile you can join my discord and get access to the Special Quality Profiles channel (access-to-sqp) by accepting the rules.

    This is a special quality profile I created for people who are really interested in it.

    This release profile is fine tuned for when you want to run a 2nd Radarr for 1080p, and want minimum to none transcoding and smaller sizes for the second copies.

    Why choose this quality profile? ↩
