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.
You can copy data from docker volumes to somewhere on the host node to do the backup from there. You can also have a container using the volumes and from there you can send directly to remote, or map a dorectory on the host node to copy the files to.
If you are running a database or something stateful, look at best practices for backup and then adjust to it.
Or not use volumes and map onto the host node directly. each works, and had its own advantages/disadvantages.
