Docker user: I'm just curious on how you'd back up a docker container

Q: I’m just curious on how you’d back up a docker container data especially when you can’t map the data portion of it

A: You can map the data portion, just Windows ownership permission tends to conflict with Linux. Quite a few workarounds though.
For docker windows permission seems to be the issue.

A: For windows, create a .env and add COMPOSE_CONVERT_WINDOWS_PATHS=1
