I remember watching your video about unifi video with Raid storage.
As I have been doing some testing with unifi protect, I did an upgrade of the hard drive. In that process I got to thinking about your freenas setups and wondered if there was a way to connect to an external storage via network.
What are your thought and ideas, maybe a daily/weekly backup that copies the data to storage, and clears the drive.
There is not any official way that I am aware of to make it work, but you could SSH into the system and build scripts that could make it happen.
