Opening BACKUP files
Did your computer fail to open a BACKUP file? We explain what BACKUP files are and recommend software that we know can open or convert your BACKUP files.
What is a BACKUP file?
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.
Software that will open, convert or fix BACKUP files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
