Back up a container
Snapshot a container's volumes and image together.
Fill it in
What to back up.
Your prompt
Back up . `container backup` captures the volumes and the image together, which is what makes the backup restorable rather than merely stored. Report what was captured and how large it is. Then say what is NOT in it: anything written outside a declared volume does not survive, and that is usually what someone discovers at restore time.
