kamal-backup gives Rails teams a small, Kamal-native way to run encrypted backups on a schedule, verify restores, and produce review evidence without maintaining separate backup glue.

The project is packaged as a Ruby gem and a production accessory image. It uses restic as the backup repository format, supports PostgreSQL, MySQL/MariaDB, and SQLite database exports, and can include file-backed Active Storage paths mounted into the backup accessory.
