pg_rman is an online backup and restore tool for PostgreSQL.

The goal of the pg_rman project is providing a method for online backup and PITR as easy as pg_dump. Also, it maintains a backup catalog per database cluster. Users can maintain old backups including archive logs with one command.

  • Backup validation. Backup can be validated with CRC checks.
  • No transaction lost in restore. Configuration file generator for point-in-time recovery is supported.
