6. Backup / Restore Volumes Container

How can I backup a Docker-container with its data-volumes?

Backup Script

# $ volume_backup.sh old_container /srv/www
# $ sudo docker stop old_container && sudo docker rm old_container
# $ sudo docker run -d --name new_container myrepo/new_container
# $ volume_restore.sh new_container
#
# This script allows you to backup a single volume from a container
# Data in given volume is saved in the current directory in a tar archive.
#
#              Backup Command
#   ./backup.sh mysql.keycloak.foundation /var/lib/mysql
#
CONTAINER_NAME=$1
VOLUME_NAME=$2
#CONTAINER_NAME="mysql.keycloak.foundation"
#VOLUME_NAME="keycloak_mysql_data"
usage() {
echo "Usage: $0 [container name] [volume name]"
exit 1
}
echo "### step 01"
if [ -z $CONTAINER_NAME ]
then
echo "Error: missing container name parameter."
usage
fi
echo "### step 02"
if [ -z $VOLUME_NAME ]
then
echo "Error: missing volume name parameter."
usage
fi
echo "### step 03"
sudo docker run --rm --volumes-from $CONTAINER_NAME -v $(pwd):/backup busybox tar cvf /backup/backup.tar $VOLUME_NAME

Restore Script

#Usage can be like this:
#
#$ volume_backup.sh old_container /srv/www
#$ sudo docker stop old_container && sudo docker rm old_container
#$ sudo docker run -d --name new_container myrepo/new_container
#$ volume_restore.sh new_container
#
#
## This script allows you to restore a single volume from a container
# Data in restored in volume with same backupped path
#
#          Restore Command
# ./restore.sh new_container
#
#
NEW_CONTAINER_NAME=$1
usage() {
echo "Usage: $0 [container name]"
exit 1
}
if [ -z $NEW_CONTAINER_NAME ]
then
echo "Error: missing container name parameter."
usage
fi
sudo docker run --rm --volumes-from $NEW_CONTAINER_NAME -v $(pwd):/backup busybox tar xvf /backup/backup.tar
