June 11, 20242 yr I recently reinstalled Unraid because I was having some problems. I still have the appdata folder and I have restored it, but now Unraid says the configuration files cannot be found. I still have a flash backup, but I don't know which file/s I need to restore the configuration file/s for the docker images. Also, it would be very helpful if we had a guide on how to backup docker images. It was my impression that simply backing up data was enough, but it seems it is not.
June 11, 20242 yr If you have the appdata folder, restore the templates-user folder to /config/plugins/dockerMan and then: https://docs.unraid.net/unraid-os/manual/docker-management/#re-create-the-docker-image-file Also see below if you have any custom docker networks: https://docs.unraid.net/unraid-os/manual/docker-management/#docker-custom-networks
June 11, 20242 yr Author Thanks for the instant help @JorgeB Much appreciated! I am still a beginner Unraider so please help me understand: Where can I find /config/plugins/dockerMan What is a custom docker network? I don't remember setting up one. Although I did pass some docker networks to another using --net=container:XYZ

June 11, 20242 yr Author Do I need to shut down everything, take out the stick, transfer the files, and put it back in? Or is there a simpler way?
June 11, 20242 yr Author The list of Docker installs is blank, but I have copied the app data content from the backup. What's going on? I also copied everything under \config\plugins\dockerMan to the flash drive and rebooted. What am I missing?
June 11, 20242 yr After that you need to recreate the docker image: https://docs.unraid.net/unraid-os/manual/docker-management/#re-create-the-docker-image-file Also see below if you have any custom docker networks: https://docs.unraid.net/unraid-os/manual/docker-management/#docker-custom-networks

June 11, 20242 yr Author Ok so I tried to go to previous apps, but only some show up. These are the apps I installed from scratch before attempting to restore tye previous docker apps.

Did you restore to the current flash drive the xml templates from the backup of the flash drive you said you have? they need to be present to get the Apps->Previous Apps to know what to offer.
June 12, 20242 yr Author Solution OK, I copied over /config/plugins/dockerMan once again, and I got it to work. Thanks guys! For future Unraiders the solution was namely to do as jorgeB mentioned, but more specifically: Copy the contents of the backed-up appdata to the production version of appdata Copy the contents of config/plugins/dockerMan from your backed-up flash drive to /config/plugins/dockerMan on the production flash drive. Re-create the docker image file. Re-install the previous docker applications Edited June 12, 20242 yr by Bob-omb
