Docker volume how long and safe it is

Hello all. I am using volume to persist data from mysql containers.

  1. What I’m interested is that how safe it is ? maybe volume gets deleted at all? then mysql data is lost and I’m screwed.

  2. where does this volume get stored ? i couldn’t find on host machine at all. I’m using windows and how do I find the volume on my host machine? it prints something like /var/lib/docker/data/ this path won’t exist on windows. so?
