Files that contain the .backup file suffix are used by a variety of software applications to store application backup files. The extension commonly used by the pgAdmin II application for PostgreSQL database backup files. These files allow the software to backup the application contents so that a user can restore the data if it becomes lost or corrupt at a future point in time.
The ISAPI application also uses the .backup file extension for the backup files that are created with the software. Other programs that use the .backup file suffix for backup files include the Ad-Aware application, Navicat and MySQL.
