Restic

Restic, a modern backup program which supports many different storage types.

The setup in this repository will use MinIO, an Amazon S3 compatible object storage, as backup target. Further we'll make use of:

  • The official restic/restic container image
  • Docker 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

Setup

  1. Get your MinIO server running or make use of the IN-Ulm MinIO Service
  2. Setup a S3 bucket with MinIO MC
  3. Setup Restic
# Setup your config
cp .env.template .env
vi .env

# Run the container
docker-compose up -d
docker logs restic -f

Operation

Monitoring

For monitoring purposes the script data/restic/push-metric.sh is executed prior to and after any backup. If the environment variable $PROM_GW_URL is set, the respective Prometheus Push Gateway will get informed about the backup start and result (stop, incomplete, fail). In case of a proper stop, further statistics will be send to the Push Gateway.
