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.

>Besides sometimes you need to run software that is not available on linux.

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.
