Is it necessary to routinely perform daily, weekly and monthly scripts as well as repairing disk permissions on Leopard? If so, should it be done manually or is there software that works? I used to have Onyx, but the version I can find doesn't work on Leopard. I looked at Cocktail, but I wanted to ask around before buying it. Also, does SuperDuper work on Leopard? I have Time Machine running on my iMac, but I don't have a drive connected to my MBP while using it. I think there was some discussion on whether Time Machine and Superduper actually achieve the same thing anyway.
