Ready to run Docker image to backup volumes


Docker image that allows you to backup volumes from your containers to a specific path on host.

This image is generic, thus you can obviously re-use it within your non- related EEA projects.

  • :latest (default)
  • :1.0
  • :1.1

Base docker image

Source code


  1. Install Docker.


Note that /var/local/dockerbck is the path on host where you want this to backup your docker data containers. Please modify it according with your needs. As a best practice this should be on a different drive (external hard- disk, nfs, etc.)

This will create a folder at /var/local/dockerbck/volume-copy if it does not exist and will store the volumes content in there.

At each run the container will leave a last run timestamp file in the backup directory e.g. /var/local/dockerbck/lastrun-dockervolbck. This file can be used to monitor when the backup cron job was last run.

Single run

$ docker run --rm \
  --volume=/:/rootfs:ro \
  --volume=/var/lib/docker/:/var/lib/docker:ro \
  --volume=/var/local/dockerbck:/backup:rw \

Run daily at 0:20 AM

$ docker run --rm \
  --volume=/:/rootfs:ro \
  --volume=/var/lib/docker/:/var/lib/docker:ro \
  --volume=/var/local/dockerbck:/backup:rw \
  -e "SCHEDULE=20 0 * * *" \ 

Run via docker-compose daily at 0:20 AM

First time deployement

$ git clone
$ cd eea.docker.volumesbackup

Edit the docker-compose.yml if you need to change backup path or SCHEDULE time

  restart: always
  image: eeacms/volumesbackup:1.1
  - /:/rootfs:ro
  - /var/lib/docker:/var/lib/docker:ro
  - /etc/localtime:/etc/localtime:ro
  - /var/local/dockerbck:/backup:rw
  - SCHEDULE=20 0 * * *


$ docker-compose up -d
$ docker-compose logs # if you want to see the running process output


$ docker-compose stop    # stop the running containers
$ git pull origin master # and get the docker-compose.yml containing the latests tags
$ docker-compose pull    # get the images and their tags

$ docker images | grep eeacms # inspect that the new images have been downloaded
$ docker-compose rm -v
$ docker-compose up -d


If you are running this as a service make sure you also sync host time with docker container time, otherwise the cron will run at 3:30 AM UTC time and not your local time. See bellow how to fix this:

$ docker run --rm \

Supported environment variables

  • SCHEDULE Schedule backup at specific time with cron (e.g. SCHEDULE=30 3 * * *) Check wikipedia for more details about crontab format.
