The purpose of this guide is to go over the step by step instructions of how to back up a Docker container on the Linux command line. We’ll also show how to restore a Docker container from backup. This can be done on any Linux system where Docker is installed, and will work on any Linux distribution.
To understand the Docker container backup and recovery process we first need to understand the difference between a Docker image and a Docker container. A Docker image contains an operating system with possibly one or more preconfigured applications, whereas a Docker container is a running instance created from an image.
