Databasus vs mariadb-backup

Databasus is free, open-source, self-hosted database backup software for Linux and web deployment, with PostgreSQL as its primary focus. It also supports MySQL, MariaDB, and MongoDB. PostgreSQL workflows include logical backups, physical full and incremental backups, and WAL streaming for point-in-time recovery; physical, incremental, and WAL options require PostgreSQL 17 or newer. Schedules can run hourly, daily, weekly, monthly, or through cron. Destinations include local storage, S3-compatible storage, Cloudflare R2, Google Drive, Azure Blob Storage, NAS, FTP, SFTP, and rclone. The service can periodically restore a recent backup in a temporary database container and report the result. It includes access management, teams, projects, and audit logs. Databasus says credentials and backup files use AES-256-GCM encryption, while database access is read-only with SELECT permissions. Installation supports a Linux script, Docker, Docker Compose, and Helm for Kubernetes. The Free, open-source software plan costs nothing under Apache 2.0 and includes all described features.

mariadb-backup is a free, open-source tool for physical backups of MariaDB tables, including while the server is running. Available on Linux and Windows for self-hosted deployments, it supports InnoDB, Aria, MyISAM, and MyRocks. Backup options include full, incremental, and partial copies, point-in-time recovery, and restoration of individual databases, tables, or partitions. It can make hot online InnoDB backups and uses a nearly non-blocking method for full backups on running systems. It also supports Galera Cluster state snapshot transfers, InnoDB page-compressed tables, and tables protected by data-at-rest encryption; encrypted tables stay encrypted in the backup. Output can be streamed to stdout for piping to tools such as OpenSSL or gzip. Restoring requires preparation with the --prepare option, and safe full or incremental restores require an empty MariaDB data directory. Backup operations connect to the running server and generally require global RELOAD, PROCESS, LOCK TABLES, and BINLOG MONITOR privileges. The listed plan is free.
