I've used CCC for the first time, to make a backup of my mac pro boot drive, in the event of a complete failure. Namely, to be able to get right back up and running from where I am now. So I chose the ASR option, and I ended up with 2 files: xxxx_asr.002.dmgpart xxxx_asr.dmg The CCC docs don't explain this part very well. Do I need to keep both of these files? If I want recreate my hard drive, what do I do?
