Page 1 of 2 But I'm not convinced that a nightly cloning provides adequate backup. It's great for disaster recovery (especially if you have a mechanism to protect the files that change during the day), but there's just too much risk that you won't notice a problem until after you've cloned the main drive, overwriting the previous clone in the process. While drives are a lot cheaper than they used to be, I don't think many people are ready to buy five (or seven) drives so they can use them in a weekly rotation. I do like Shirt Pocket's idea of using SuperDuper alongside Time Machine. That way you get the reassurance of a bootable drive if the worst happens, plus the ability to easily restore the last-known-good version of an accidentally deleted, incorrectly modified, or mysteriously corrupted file. You're going to need a large hard drive for the job. We tend to fill disks rapidly these days, so if you're running a 320G hard disk (as provided on two of the four standard iMacs configurations), you'll probably find at least 200G occupied after using it for a while. You will therefore need 400G just to start using SuperDuper and Time Machine, which means a 500G drive will soon fill and a 750G unit will be a better idea. CONTINUED |
