I am trying to work out what the difference is between a backup and a clone. I have already made a bootable Acronis T.I. v11 CD from the Acronis Utilities. I have also made a full Hard Disk backup (tib file) onto an external USB hard drive. My understanding is that if my hard disk fails or breaks, then I can install a brand new unformatted hard disk, and using the bootable CD, restore from the tib file on the external hard drive. Is this correct ? If this is the case, why would I need to clone ? Thank you all in advance or your understanding and assistance.
