Use the Open Backup Copy window to select the backup file you want to restore.
To do this task
If your backup file is on a CD, USB flash drive, or other storage device, insert or connect that device now.
If your backup file is on your hard drive or a network drive, click the Look in drop-down arrow and browse to the location where you saved the backup file, which will have a .qbb file extension (for example, mycompanyname.qbb).
Select the file you want to restore. The file must have a .qbb extension.
