Database Vault vs WAL-G

Database Vault is a cloud service for automating database backups and restoring earlier snapshots. It supports PostgreSQL, MySQL, MongoDB, Firebase, and Supabase; the supported-database list also includes SQLite. Backup schedules can be hourly, daily, weekly, or custom. Users can review backup history and restore a point-in-time snapshot, including through a one-click restore to a new database. The service monitors failures, retries automatically, and provides notifications and operation logs. Its dashboard tracks backup frequency, storage use, and success rates. Database Vault says backups are encrypted with AES-256 before storage and connection strings are encrypted at rest and never logged. It runs on Google Cloud Platform infrastructure, which it describes as SOC 2 Type II certified, and advertises a 99.9% uptime SLA for backup operations. The Free plan includes 1 GB of storage and 7-day retention. Starter costs $9 a month and supports up to three databases; Pro costs $15 a month and supports up to ten. Backups remain accessible for 30 days after cancellation.

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.
