That's the ultimate test.
However (if you feel comfortable with this) there are a few shortcuts:
1. When creating your backup images, be sure to check the "verify backup" option. That verifies the backup file structure after the backup.
2. Do a "minor" test restore. Delete one of your documents (or rename it) and then use the Ghost Explorer to browse and restore a single file or folder.
Of course restoring onto a new blank unformatted hard drive is the utlimate test.
