Sometimes it's necessary to restore data from a backup file. If, for example, you enter a large amount of incorrect data, you can restore a previous version of the data and enter the correct information. Restoring data can be a better option than fixing the multiple incorrect entries in your current files.
You can use restore functions to move data to a newly purchased computer on which you install PDS. You can also use a backup to replace files lost due to hard drive failure or file damage.
You cannot restore backup data from read-only media such as CD-ROM disks. To restore data included on read-only media, copy the file to a rewritable drive, and then clear the Read-only option in the Microsoft Windows file properties dialog box. For more information, see your operating system documentation.
When you restore data from a backup, you overwrite data entered after the backup was created.
