Percona Backup for MongoDB vs Quemsi

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.

Quemsi is a hybrid tool for database backup and restore, with a web UI for tagged snapshots, timeline history, and one-click restoration. It supports MySQL, PostgreSQL, SQL Server, and MongoDB. Backup and restore flows can include custom steps such as stopping services or running scripts, and backups can go to AWS S3, Azure Blob, or local drives under the user's control. Its agent runs operations inside the user's infrastructure, while the cloud service handles metadata rather than database content. The agent is open source and can be audited, modified, or built from source. Agent-to-cloud communication uses TLS 1.3, agents use certificate-based mutual TLS, and SHA-256 checksums verify backup integrity. Agents are available for Windows, Linux, and macOS, and can also run as a Java JAR or Docker container. The free Solo plan costs nothing and includes unlimited databases, environments, and flows for one user, with community support.
