Hi all
I’m running several docker containers with local persistent volumes that I would like to backup. I haven’t found an easy method to do so.
What do you use / recommend to do that? AFAIK you can’t just rsync the volume directory while the container is running.
I don’t even understand what the advantage is to using volumes rather than mounts? So I too always use mounts.
I think volumes are useful when you don’t want to deal with those files on the host. Mainly for development environments.
I wasn’t able to understand volumes at first, and my team mate told me I had to use binders to run mysql. My project folder used to have a docker/mysql/data. Now I just point MySQL data to a volume so I don’t loose data between restarts. And I don’t have to deal with a mysql folder on my project with files I would never touch directly.
In my opinion, volumes are useful for development / testing environments.
I’m not sure either. The only thing I could come up with is that with volumes you don’t have to worry about file ownership. That’s usually taken care of for you with volumes from what I understand.
