The Backup Data File feature allows you to backup your Plant Estimator data file to a sperate file. This file can be on your hard drive or on a CD, floppy disk or other removable media. Incase of hard drive failure you should backup your data to a removable disk.
Plant Estimator automatically makes a backup of your data file when you open it. These backups are saved in the Backup folder within the folder where Plant Estimator is installed.
The Restore Data File feature lets you restore a backup file to a normal Plant Estimator data file. You would only ever need to restore a backup in case of an emergency where you main data file was lost or damaged.
