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.
In general there is no problem in rsync’ing the volume bind directory. But that depends on the application, which is running in the container. I. e. you should not copy the files of a running database. It may corrupt the data while it’s being written.
