Volume Backup

Simple volume backup.

Inspired by loomchild/volume-backup.

I needed support for non-root access. Here you go.

Usage

Volumes

Mount to following volumes:

• /volume: The volume to backup. Usually a named volume.
• /backup: The backup archive is stored here. Usually a host volume.

Configuration

Configuration is done using environment variables.

Variable	Default	Description
UID	1000	The user ID the archive should be owned by.
GID	1000	The group ID the archive should be owned by.
ARCHIVE_NAME	volume	The archive basename.

Example

docker run --rm \
    -e ARCHIVE_NAME=important \
    -v important:/volume \
    -v "$HOME/backup/data:/backup" \
    axelrindle/volume-backup

Output:

             _                             _                _
            | |                           | |              | |

                                                                      |_|


We're gonna pack an estimate of 34.3M. Please be patient...

+ tar c -f /backup/important.tar -C /volume .
+ pigz /backup/important.tar
