I broke my cache drive, now all my dockers are gone, am I screwed?

Hi, first off I'm sorry for the noob questions, I'm new to unraid.  
I had 2 cache drives running in raid 0 like an idiot as I just built this server last month needed a lot of cache. Last night I went to swap one of the cache drives to add a 2nd parity drive and now all my dockers are gone. 
I though I did the process of removing the drive correctly but obviously I broke my cache and now all my dockers appear to be gone. 

Anyway my question is, is there anything I can do? I did not have a good understanding of how Unraid cache worked, I though it meant there was a copy of whatever was on the cache on the main, I didn't relies the dockers lived on my cache. I appear to still have a docker image file that is 21gb on my main, is there anything I can do with that? 

Again, thank you and sorry for the noob question.  
For the futeu I will use that CA backup plugin, I was not aware of it, I'm still learning

Docker image can easily be recreated but to keep all the settings you need the apddata folder, do you have a backup? Also make sure it was on cache, it might be in the array.

I have this, what would the location of the appdata be? (sorry again for the noob question)

That's the docker image, go to shares and click on "calculate all" then post a screenshot, you can post images on the forum.

Somehow I was able to get it back by plugging in the old cache drive, I thought for sure it would be broken as it was part of a raid0
Thank you for the help
