It is possible to run multiple instances of Radarr. This is typically done when one wants a 4K and 1080p copy of a movie. Note that you can (and probably should) review TRaSH's guide and configure Radarr to use a second Radarr as a list. This is helpful if you wish to keep both in sync.
The following requirements should be noted:
-data= or /data= argument passed/config must be usedThis guide will show you how to run multiple instances of Radarr on Windows using only one base installation. This guide was put together using Windows 10; if you are using a previous version of Windows (7, 8, etc.) you may need to adjust some things. This guide also assumes that you have installed Radarr to the default directory, and your second instance of Radarr will be called Radarr-4K. Feel free to change things to fit your own installations, though.
Note: You should run Radarr as either a service or as a tray app. Running both an app and a service is unnecessary and likely to cause issues.
nssm stop Radarrsc config Radarr binpath= "C:\ProgramData\Radarr\bin\Radarr.exe -data=C:\ProgramData\Radarr"This command tells the original instance of Radarr to explicitly use
C:\ProgramData\Radarr for its data directory. If you didn't use the
default Radarr install, or if your data folder is somewhere else, you
may have to change your paths here.
C:\ProgramData\Radarr-4Knssm install Radarr-4K. A popup window will open where you can type yourC:\ProgramData\Radarr\bin\Radarr.exeC:\ProgramData\Radarr\bin-data=C:\ProgramData\Radarr-4KNote that Arguments points to the new folder created in step 1.
This is crucial, as it keeps all the data files from both instances in
separate locations.
/data= argument in the 'target' field to allow multiple instances%appdata%\Microsoft\Windows\Start Menu\Programs\Startup and edit the existing shortcut if needed.C:\ProgramData\Radarr-4KC:\ProgramData\Radarr\bin\Radarr.exe /data=C:\ProgramData\Radarr-4KRadarr-4K and finish the wizard.Port Number from 7878 to a different port e.g. 7879 so Radarr and Radarr4k do not conflict
- Disable automatic updates in one of your instances
<Branch>nonexistent</Branch>Configuring the NSSM Exit Action correctly should allow Radarr to update and restart multiple instances with no additional scripts.
If the restart delay is not configured by default it will restart the instance immediately.
This can prevent updates from being applied and can result in the following errorRadarr was restarted prematurely by external process.
