# Handle file uploads using third party tools
|
|
|
|
If you want to use an unsupported storage backend, or want to use a third party (e.g. rsync, rclone) tool for file uploads, you can build a Docker image containing the required binaries off this one, and call through to these in lifecycle hooks.
|
|
|
|
For example, if you wanted to use `rsync`, define your Docker image like this:
|
|
|
|
```Dockerfile
|
|
FROM offen/docker-volume-backup:v2
|
|
|
|
RUN apk add rsync
|
|
```
|
|
|
|
Using this image, you can now omit configuring any of the supported storage backends, and instead define your own mechanism in a `docker-volume-backup.copy-post` label:
|
|
|
|
```yml
|
|
version: '3'
|
|
|
|
services:
|
|
backup:
|
|
image: your-custom-image
|
|
restart: always
|
|
environment:
|
|
BACKUP_FILENAME: "daily-backup-%Y-%m-%dT%H-%M-%S.tar.gz"
|
|
BACKUP_CRON_EXPRESSION: "0 2 * * *"
|
|
labels:
|
|
- docker-volume-backup.copy-post=/bin/sh -c 'rsync $$COMMAND_RUNTIME_ARCHIVE_FILEPATH /destination'
|
|
volumes:
|
|
- app_data:/backup/app_data:ro
|
|
- /var/run/docker.sock:/var/run/docker.sock
|
|
|
|
# other services defined here ...
|
|
volumes:
|
|
app_data:
|
|
```
|
|
|
|
{: .note }
|
|
Commands will be invoked with the filepath of the tar archive passed as `COMMAND_RUNTIME_BACKUP_FILEPATH`.
