kamal-backup Scheduled backups for Rails apps deployed with Kamal

How It Works

GitHub

🕒

Runs on a Schedule

Boot the accessory and it runs kamal-backup schedule by default. Set backup_schedule_seconds and keep daily backups moving without cron glue.

🗄️

Databases and Active Storage

Back up PostgreSQL, MySQL/MariaDB, or SQLite with database-native tools, plus file-backed Active Storage files from mounted volumes such as /data/storage.

🔒

Restore Drills Built In

Restore locally or into scratch production-side targets, run verification commands, and record the result instead of trusting backup logs.

✅

Evidence for Security Reviews

Produce redacted JSON with latest database and Active Storage snapshots, restic check, restore drills, retention settings, and tool versions for security reviews like CASA.
