In their own words
Percona Backup for MongoDB
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.
WAL-G
WAL-G is a free, open-source archival and restoration tool for databases in cloud environments. It supports continuous backups and point-in-time recovery, with documented support for PostgreSQL, MySQL, MariaDB, and MS SQL Server; MongoDB and Redis are marked beta. Other listed database targets include Greenplum, Cloudberry, FoundationDB, and ETCD. Compression options are LZ4, LZMA, ZSTD, and Brotli, using multiple processors. PostgreSQL users can take non-exclusive base backups. Operators configure backup storage and interact with it through storage tools commands. Configuration accepts environment variables or JSON, YAML, and envfile formats. Encryption can use libsodium, OpenPGP, or Yandex Cloud KMS, but is disabled by default; envelope PGP configuration currently supports only Yandex Cloud KMS. Metrics can be sent best-effort over UDP to statsd or statsd_exporter. WAL-G runs on Linux, macOS, and Windows builds.
