The greatest strength of venti, and also of the worm file system, is that once data is written, those disk blocks are never changed again. That makes it virtually impossible to lose data due to software or human errors. This is no small thing. Why not just use an ordinary file system? What benefit are you deriving from using venti that is making all this rewriting worthwhile? If it's just that when two people upload the same file, you don't store it twice, you could just store files named by their SHA1 hashes in an ordinary file system. Russ
