pg_probackup vs SqlBak

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.

SqlBak automates database backups and provides a web service for managing backups from multiple servers. It lists support for SQL Server, PostgreSQL, MySQL, Azure SQL, Amazon RDS for SQL Server, and MongoDB. Destinations include Amazon S3, Google Drive, Dropbox, OneDrive, Microsoft Azure, S3-compatible storage, Backblaze B2, Box, Wasabi, Google Cloud, Aruba Cloud, Yandex Disk, FTP, local or network folders, and SSH. SQL Server tools include point-in-time recovery, full, differential, and transaction-log backups, automatic verification, compression, health monitoring, and one-click restore. The app runs as a background service on Windows or Linux servers; Docker and Raspberry Pi installation are also described. SqlBak says backups are encrypted and sent directly from the server to the user's storage, while database credentials are encrypted and kept on the server. The Free plan covers one server, two databases, and one month of backup history. Standard costs $6 a month per server, and Professional costs $9 a month per server. A 30-day trial of Professional features requires no credit card to start.
