How are you managing backups of your containers? What about Backups of Containers to https://hub.docker.com/repository/docker (alien.top)

Hey - so I am just getting started with self hosting and docker containers.

I have found that I can backup all my containers to this location easily via script https://hub.docker.com/repository/docker

My largest container compressed size in my private repository is 3GB.

I was wondering if backing up to a hub.docker private repository is okay and if there is going to be cost/limitations to doing that?

What are you using for backing up your containers? I noticed people often expressing importance of backups but then not sharing how they are doing their backups and their backup setup.

I don't think backing up the container is the right strategy, as containers (I think***) is built for portability. So you can spin one up in seconds, or migrate to another machine with very little hassle.

For me I backup the docker host itself and the docker config files in the volumes with a script. I make the somewhat redundant back up of the config files in addition to the host is because I like to tinker things, and usually nuke something in the process. Having a more frequent backup of the docker configs allows me to easily restore if something goes wrong.
