Percona Backup for MongoDB vs pg_probackup

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.

pg_probackup is a free utility for backing up and recovering PostgreSQL database clusters. It supports full backups and page-level incremental DELTA, PAGE, and PTRACK modes, along with incremental and partial restores. Point-in-time recovery uses WAL archives. The utility can check data consistency automatically, validate backups on demand, and verify PostgreSQL instances with checkdb. Retention policies can use recovery time, backup count, or a time-to-live value; expired backups can be merged or deleted. Backup, restore, merge, delete, validation, and checkdb tasks can run on multiple threads. It supports remote PostgreSQL instances and backups from standby servers. Postgres Pro Enterprise edition supports S3 storage through MinIO, Amazon S3, and VK Cloud. The repository lists compatibility with PostgreSQL 13 through 18. Linux packages and Windows installers are available. Remote backup over SSH is not supported on Windows, and SSH operations require matching local and remote pg_probackup versions. The license permits use, copying, modification, and distribution without a fee, but disclaims maintenance, support, updates, and warranties.
