backup-volume.sh will create a new running docker container and mount the volume to the container. A docker cp will be run and the contents of the volume will be saved into a location determined by:

$prefix/$volume/<timestamp>_$volume.tar.gz

An example to run the command is the following:

backup-volume.sh -v <volume_name> -p <prefix>

Volumes can be restored using create-volume-from-backup.sh by invoking it in the following manner:

create-volume-from-backup.sh -v <volume_name> -p <prefix>

Optionally if you wish to create a volume with a different name from the backup the script can be invoked in the following manner:

create-volume-from-backup.sh -v <volume_name> -p <prefix> -n <new_volume_name>

The animation below illustrates how the docker volume owncloud-docker_files is saved to /tmp/backups/owncloud-docker_files. The volume is saved as a zipped tar file with the date and time it was saved.

The following animation shows how the docker volume is restored from /tmp/backups by specifying the snapshot file to restore fom. Note: If you wish to restore the docker volume with a different name than the backup, this can be done by adding a -n flag to the command and specifying the new volume name.

We hope this code is useful for you.
