I am a little nervous about doing a restore. My HHD crashed and I want to restore the backup to and external hard drive that the backup is currently on. How can I do it. If it is a complete backup or clone backup will it erase the the backup information that is on the EHDD. Will it be bootable from the EHDD or will I need to install the OS on the EHDD. Thank you. Many questions to follow in an sure.
