View Full Version : Backing up an external drive to an external drive

10-27-2007, 03:03 AM
I would like to know if SuperDuper will allow me to also backup my external drive to another external drive. I have my photos and music saved on an external drive due to the large number of songs and photos I have. If I kept them on my iMac drive they would take up nearly 90% of the available space. So, I keep them on an external firewire drive.

I want to backup my iMac hard drive and the external drive with my photos to a second external drive which will be big enough to hold all this data.

Can SuperDuper do this? And can it make the external backup drive bootable while it does this backup?

Sure it can do this, but no, the drive won't be bootable because it doesn't have any OS on it. Only drives that were originally bootable are bootable when copied.

I thought Superduper automatically made a bootable drive backup when it did the initial backup. That is what friends who tell me to buy it are saying. Am I wrong?

If a drive has no OS on it, it can't boot, because it doesn't have an OS... so, while we automatically make a backup of a bootable drive bootable, we can't do that for something that isn't bootable.
