This product also handles backing up an operating system?
I am going to migrate to yosemite on my mac. I need a full backup of my mac. Will this product do that? I have a minimal amount of files - most of them are in the cloud.
Yes it will/does backup to your Mac. I have a Macbook Pro and my files are also in icloud. However, I wanted an external backup, and the Seagate is reasonably priced and gives me the peace of mind. I have the latest system (OX system??) that came after the yosemite and it's working just fine. NO WORRIES !!
