Backing up entire VMs with all the configuration in case an update breaks something or just bricks your server is a smart idea aswell as running stuff in containers. Also, 4GB per VM? Besides sometimes you need to run software that is not avaliable on linux.

If you backup the entire VM you are just backing up the Linux kernel itself and all the (GNU) tools with it.

Seems like a waste to me.

Backup your docker config and your data, that's what you actually need. The rest is just available online if you ever need it.

Really, like what?

Good backup software deduplicates on storage. Proxmox backup server for example.

Not all server executables for video games are avaliable on linux for example. There is a lot of use cases and just saying "you just need X" is somewhat of an ignorant statement. No, I don't.
