> require more setup to secure

docker is not secure. It has no "real" security boundry, and any malicious actor could have you run a docker image that is just as malware as an executable. Like locks on doors, it just keeps out the honest people. So i say effort spent trying to secure it is wasted.

> backup

if you have data in the docker instance, you have to use volume mounts, and then backup that volume mount. I say it's easier to backup than an installed app, as you cannot be sure that it didnt write somewhere else their data!
