Needs a new backup system

この提案は、Docker CLI に新しい docker backup --all コマンドと docker restore --all コマンドを追加するものです。まず CLI のエントリーポイントと既存の volume または archive の処理箇所を特定し、次に移植性と復旧の要件を定義します。完了条件には、使用可能な backup と restore のフローと、サポート対象のデータを網羅するテストを含める必要があります。

Description

The backup system in docker is the worst most garbage backup system I've ever seen in my 25 years of living and in any software. I spent over 5 ****** hours trying to recover MY data, have about 11+ years of experience in IT and many years with self-hosted apps in docker can't because the backup system in Docker is unusable.

Basically you store anything in a docker volume, just assume it can never be reached again except for that exact computer. Someone spends hours of their life self-hosting something they need for day to day work and their computer dies? Screwed out of all that date, If this were an enterprise that needs uptime it would be billions of dollars lost over bad programming.

I tried copying /var/lib/docker but that doesn't work for some magic reason. I did exact copy with rsync, exact permissions and even factoring in ACLs and any minute little thing, nope. Don't work. How is this even possible? How can a program just not at all recognize the exact data on another computer unless it's deliberately coded to frustrate the end user.

Here is how it should work:

docker backup --all

Then it just makes a zip file, then to restore:

docker restore --all

Whoever made this system needs to fire them immediately they are an active hindrance to your project. Multi billion dollar enterprises are losing time and money on this joke of a system and they should be fired immediately.
