You need to make your own plan about what’s important to you. Don’t waste time backing up stuff you can quickly download again - like docker images. Just know where the stuff is that you care about (such as any mounted volumes in docker with your own data on) and back that up, and make everything automated. If you do it manually, chances are you’ll gradually stop doing them.
I wrote some things about properly backing up data that may be of use.
Great tool. It’s also leveraged by pinchflat, where you add Youtube channels via a webui and it downloads their videos and adds them to Jellyfin.
