mariadb-backup vs Zmanda Recovery Manager for MySQL

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.
