mariadb-backup vs Percona Backup for MongoDB

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.

Percona Backup for MongoDB (PBM) is a free, open-source tool for consistent backups and restores of MongoDB replica sets and sharded clusters. It supports point-in-time recovery by saving oplog slices between backups. Operators can manage operations from its command-line interface or through a web interface with Percona Monitoring and Management. PBM offers logical, physical and incremental physical backups, plus backups of selected databases or collections; whole-database backups can include users and roles. Destinations include Amazon S3, Google Cloud Storage, MinIO and compatible storage, filesystem servers, Azure Blob Storage, Oracle Cloud Infrastructure Object Storage and Alibaba Cloud OSS. Backup types depend on database product, version and storage engine. MongoDB Community and Enterprise Edition support logical backups only. Physical backups require Percona Server for MongoDB 7.0 or newer and WiredTiger. PBM is self-hosted and lists Linux among its platforms. It uses MongoDB authentication and authorization, and requires a PBM user in the admin database for each replica set. Percona recommends systemd credentials rather than storing connection credentials in plaintext environment variables or service files.
