mannp/restic-robot repository overview

⁠Restic Robot

Backups done right... by robots!

This is a small and simple wrapper application for Restic⁠ that provides:

• Automatically creates repository if it doesn't already exist
• Scheduled backups - no need for system-wide cron
• Prometheus metrics- know when your backups don't run!
• JSON logs - for the robots!

⁠Usage

Just go build and run it, or, if you're into Docker, southclaws/restic-robot.

Environment variables:

• SCHEDULE: cron schedule
• RESTIC_REPOSITORY: repository name
• RESTIC_PASSWORD: repository password
• RESTIC_ARGS: additional args for backup command
• RUN_ON_BOOT: run a backup on startup
• PROMETHEUS_ENDPOINT: metrics endpoint
• PROMETHEUS_ADDRESS: metrics host:port

Prometheus metrics:

• backups_all_total: The total number of backups attempted, including failures.
• backups_successful_total: The total number of backups that succeeded.
• backups_failed_total: The total number of backups that failed.
• backup_duration_milliseconds: The duration of backups in milliseconds.
• backup_files_new: Amount of new files.
• backup_files_changed: Amount of files with changes.
• backup_files_unmodified: Amount of files unmodified since last backup.
• backup_files_processed: Total number of files scanned by the backup for changes.
• backup_added_bytes: Total number of bytes added to the repository.
• backup_processed_bytes: Total number of bytes scanned by the backup for changes

It's that simple!

⁠Docker Compose

Stick this in with your other compose services for instant backups!

services:
  #
  # your stuff etc...
  #

  backup:
    image: southclaws/restic-robot
    restart: always
    environment:
      # every day at 2am
      SCHEDULE: 0 0 2 * * *
      RESTIC_REPOSITORY: my_service_repository
      RESTIC_PASSWORD: ${MY_SERVICE_RESTIC_PASSWORD}
      # restic-robot runs `restic backup ${RESTIC_ARGS}`
      # so this is where you specify the directory and any other args.
      RESTIC_ARGS: /data
      B2_ACCOUNT_ID: ${B2_ACCOUNT_ID}
      B2_ACCOUNT_KEY: ${B2_ACCOUNT_KEY}
    volumes:
      # Bind whatever directories to the backup container.
      # You can safely bind the same directory to multiple containers.
