Default docker appdata location is not a cache-only share

I believe I've had this warning for the entirety of using unRAID. I've read about it and am still confused (my own ignorance and understanding). I don't remember changing from the default settings, but perhaps I did. I guess I believed I was backing up the cache to the array or someone suggested I do this. I have attached how I have my settings. What changes should be made? Do I simply change secondary storage to "cache"? or Should it be "None"?

 

I have my cache in a pool/mirrored on (2) NVME, so is that enough of a backup? Do I need to deleted appdata folders files from the array manually if I change the settings? Thanks for any help

The default for mover direction is Cache <- Array so you must have changed that at some point.  

 

You can use the appdata backup plugin if you want regular scheduled backups made to the array.

Thanks! Ok, I will change it back. Do I need to change "Secondary Storage" and/or anything else? Is it recommended to use appdata backup plugin, or do most consider having it mirrored to be sufficient?

No.

Up to you, but remember even with a mirror things can still go wrong.   Many do not bother with making the pool redundant and rely on the appdata backup plugin to keep a reasonably up-to-date copy.

So I changed Secondary Storage to "None" and obviously that negated the mover direction setting. I now have the warning "Share appdata set to cache-only, but files / folders exist on the array", which is related to my question regarding removing appdata files from array. Do I need to go to each individual drive on the array to delete the appdata folder?

 

Also, I have had the appdata backup installed for some time I guess. I have not changed any of its settings, so I guess it has been backing it up all along? I assumed those mover settings were moving those files/folders from cache to array. So maybe my idea of deleting mentioned in this post above is irrelevant? Sorry, quite new and confused. Thx!
