|

|
|
|
|
|
|
-This [`docker-compose.yml`](./docker-compose.yml) file runs Restic backup as per [`crontab.txt`](data/restic/crontab.txt) with parameters set in [`.env`](.env.template) using the [restic/restic](https://hub.docker.com/r/restic/restic/) image.
|
|
|
|
|
|
|
+[**Restic**](https://restic.net/), a modern **backup program** which supports many different storage types.
|
|
|
|
|
|
|
|
-### Setup
|
|
|
|
|
|
|
+The setup in this repository will use [**MinIO**](https://github.com/minio/minio), an [Amazon S3](https://aws.amazon.com/s3/) compatible object storage, as **backup target**. Further we'll make use of:
|
|
|
|
|
+- The official [restic/restic](https://hub.docker.com/r/restic/restic/) container image
|
|
|
|
|
+- [Docker Compose](https://docs.docker.com/compose/) for orchistration
|
|
|
|
|
+- Cron (in the restic container) to schedule backups
|
|
|
|
|
+- Scripts to run new and clean up old backups
|
|
|
|
|
+- Scripts to push metrics for [Prometheus](https://prometheus.io/)
|
|
|
|
|

|
|
|
|
|
+## Setup

|
|
+1. [Get your MinIO server running](https://git.in-ulm.de/ulpeters/minio/) or make use of the [IN-Ulm MinIO Service](https://s3.ulm-store.de/)
|
|
|
|
|
+2. [Setup a S3 bucket with MinIO MC](https://git.in-ulm.de/ulpeters/minio-mc/)
|
|
|
|
|
+3. Setup Restic
