# docker-volume-backup
|
|
|
|
Backup Docker volumes locally or to any S3, WebDAV, Azure Blob Storage, Dropbox or SSH compatible storage.
|
|
|
|
The [offen/docker-volume-backup](https://hub.docker.com/r/offen/docker-volume-backup) Docker image can be used as a lightweight (below 15MB) companion container to an existing Docker setup.
|
|
It handles __recurring or one-off backups of Docker volumes__ to a __local directory__, __any S3, WebDAV, Azure Blob Storage, Dropbox or SSH compatible storage (or any combination thereof) and rotates away old backups__ if configured. It also supports __encrypting your backups using GPG__ and __sending notifications for (failed) backup runs__.

## Quickstart
|
|
|
|
### Recurring backups in a compose setup
|
|
|
|
Add a `backup` service to your compose setup and mount the volumes you would like to see backed up:
|
|
|
|
```yml
|
|
version: '3'
|
|
|
|
services:
|
|
volume-consumer:
|
|
build:
|
|
context: ./my-app
|
|
volumes:
|
|
- data:/var/my-app
|
|
labels:
|
|
# This means the container will be stopped during backup to ensure
|
|
# backup integrity. You can omit this label if stopping during backup
|
|
# not required.
|
|
- docker-volume-backup.stop-during-backup=true
|
|
|
|
backup:
|
|
# In production, it is advised to lock your image tag to a proper
|
|
# release version instead of using `latest`.
|
|
# Check https://github.com/offen/docker-volume-backup/releases
|
|
# for a list of available releases.
|
|
image: offen/docker-volume-backup:latest
|
|
restart: always
|
|
env_file: ./backup.env # see below for configuration reference
|
|
volumes:
|
|
- data:/backup/my-app-backup:ro
|
|
# Mounting the Docker socket allows the script to stop and restart
|
|
# the container during backup. You can omit this if you don't want
|
|
# to stop the container. In case you need to proxy the socket, you can
|
|
# also provide a location by setting `DOCKER_HOST` in the container
|
|
- /var/run/docker.sock:/var/run/docker.sock:ro
|
|
# If you mount a local directory or volume to `/archive` a local
|
|
# copy of the backup will be stored there. You can override the
|
|
# location inside of the container by setting `BACKUP_ARCHIVE`.
|
|
# You can omit this if you do not want to keep local backups.
|
|
- /path/to/local_backups:/archive
|
|
volumes:
|
|
data:
|
|
```
|
|
|
|
### One-off backups using Docker CLI
|
|
|
|
To run a one time backup, mount the volume you would like to see backed up into a container and run the `backup` command:
|
|
|
|
```console
|
|
docker run --rm \
|
|
-v data:/backup/data \
|
|
--env AWS_ACCESS_KEY_ID="<xxx>" \
|
|
--env AWS_SECRET_ACCESS_KEY="<xxx>" \
|
|
--env AWS_S3_BUCKET_NAME="<xxx>" \
|
|
--entrypoint backup \
|
|
offen/docker-volume-backup:v2
|
|
```
|
|
|
|
Alternatively, pass a `--env-file` in order to use a full config as described below.
