Question - Docker on windows

[pfaustinopt]

Hello,

I've never worked with docker before and I was wondering if anyone could give me some guidance on how to backup the files to a windows folder?

I've attempted the following, but got no success (I don't know where docker is saving the files):
docker run -t -e TRELLO_API_KEY=*** -e TRELLO_TOKEN=*** -v c:/Backups jtpio/trello-full-backup trello-full-backup -C

Thanks for your help!
