I have five doofus-level questions. Please bear with me... ASSUMPTION for Question 1- I am seeking to better understand the difference between "Backup" (first item on ATI's "Pick A Task" menu) VERSUS "Clone Disk" (third item on ATI's "Pick A Task" menu). I *assume that* "Backup" is what I should do so I can restore Drive C (for example) in case it crashes; whereas "Clone" is what I should do in order to create a new Drive C, as in the case where I am installing a new hard drive (for instance). Q1- Am I correct in the preceding assumption? If not, please teach me. COMMENT for Question 2- The "I" in ATI stands for "image." However, there is no "Make an Image" task on ATI's "Pick A Task" menu. Instead, there are "Backup" and "Clone." Q2- Is "Backup" (first item on ATI's "Pick A Task" menu) the same thing as "Make an Image?" Q3- I now have 17 ATI-produced "Backups" on my external drive, with lots of room left. My question is -- what is your OPINION as to about how long I should keep a "Backup" before I delete it? A week? A month? What? Q4- Backup files are rather large. To delete one, should I merely select it then hit the "Delete" button? Or is there a better/faster way? Q5- Since I have plenty of room on my external hard drive, is there any good reason why I should use an incremental or differential backup AS OPPOSED TO making a full backup in each case?
