The update aims to improve performance and resource control, and also adds options for configuring WAL file storage and improving work with S3 storage.

Russian developer Postgres Professional has released a new version of its backup and recovery tool – Postgres Pro Backup Enterprise 3.3.0.

The new version implements mounting of backups via FUSE, remote recovery and recovery of individual databases, three copying modes – BASE, PRO and DIRECT, incremental backup merging, and optimization for tape storage.

According to project manager Alexey Darwin, in ProBackup 3.3.0, the developers focused on tasks important for operating large infrastructures: controlling WAL volume, reducing backup size, working with CFS, and resource management.

Two new parameters have been added for placing WAL separately from the main backup data. The --waldir parameter specifies a separate directory for WAL files during recovery and synchronization, and the --wal-archive-dir parameter indicates an alternative location for the WAL archive. The list of supported platforms has also been expanded: a build for Astra Linux 1.8 has been added.

Postgres Pro Backup Enterprise includes basic backup functionality and additional features required in large infrastructures: backup via API, storing backups in a single file, working without SSH access and PGDATA access rights, and support for all PostgreSQL 15+ versions.
