just wondering, correct me if i'm wrong. if i am experiencing some sort of problem with the main os ( snow leopard or lion, whatever), if I back it up with CCC, my problems will be there two right ? because of being bootable, it copies 1:1, can sometimes back up a wrong permission maybe? and if I do a back up with TM, i'll need to format the HD to then install the os again, and then do a restore with TM back up. this will get rid of the possible problem, better then with CCC ? any thougts are very apreciated. sorry about my poor english.
