My Book External drive 3 TB

I am looking at buying a new External drive and looking at the My Book 3 TB.  Think it comes with the Smartware Pro back up software. Is that correct?

And if so can I use to back up from my internal hard drive or OTHER external hard drives.  I WANT THIS NEW ONE TO BE THE BACK UP DRIVE>

Also with this drive and the pro software, can I back up manually without doing scheduled back ups

Yes.

The drive comes with Smartware Pro that will allow you to backup internal and external drives.

You can also use the drive without the software.

For more information about the software see the link bellow:
