I'm using both right now on my partitioned 1 TB hard drive. I have a 500GB HD on my iMac so it works perfectly since I split it 50/50. I had a question about CCC though...I've heard it's better/faster than Time Machine...how do I set it up. I have it running backups every hour (just like Time Machine) but I was wondering if I checked the right options for scans. And I made a small "Lion" Partition to my Hard Drive bc it wanted to backup the re-install in case something happens (it only took up 1 GB)...is that correct too?
