Reinstall of toolbox removes data volume - Dockerized Jira


I had to reinstall the docker-toolbox and VirtualBox that was running my Jira instance (the dockerized version), and after the reinstall I found that Jira volume is gone and probably all my data with it.

Is it really true that my data were in the volume, and now I can’t get them back anymore?

I know, next time I will do a backup before reinstall.
