I would tell it to Plan9 folks as well. There is no way to recover from a catestrophic disk failure on a Mac using venti. Two days ago I spent $137 on a 1TB external USB disk. I now have an encrypted backup of my laptop from which I can recover my complete environment on new hardware. If your scheme can't do that, it's not a backup. I.e. don't confuse 'backup' with 'archive'. If you need a backup in the true sense of the word, your only option is Time Machine. --lyndon
