Since version 0.13 autorestic supports docker volumes directly, without needing them to be mounted to the host filesystem.

Let see an example.

    docker-compose.yml1version: '3.7'
    2
    3volumes:
    4  data:
    5    name: my-data
    6
    7services:
    8  api:
    9    image: alpine
    10    volumes:
    11      - data:/foo/bar

    .autorestic.yml1locations:
    2  hello:
    3    from: 'volume:my-data'
    4    to:
    5      - remote
    6    options:
    7      forget:
    8        keep-last: 14 # Useful for limitations explained belowd
    9
    10backends:
    11  remote: ...

Now you can backup and restore as always.

    1autorestic -l hello backup

    1autorestic -l hello restore

If the volume does not exist on restore, autorestic will create it for you and then fill it with the data.

## linkLimitations

Unfortunately there are some limitations when backing up directly from a docker volume without mounting the volume to the host:

1. Incremental updates are not possible right now due to how the current docker mounting works. This means that it will take significantely more space.
2. Exclude patterns and files also do not work as restic only sees a compressed tarball as source and not the actual data.

If you are curious or have ideas how to improve this, please read more here. Any help is welcomed 🙂
