Only a 2**128 chance of that. If you know a way to force a hash collision more frequently than that, the crypto world wants to hear from you.. ;) > Also this buys you nothing. > You write file in chunks, once file is identical to other file, > one of the files deleted. Looks like just more extra work (but some saved space > of course). A much more productive way to save space is file-system compression. AIX supports LZ-compressing each 4K block and then only saving as many 512 byte fragments as actually needed. It's a big win - /usr (even with all the binaries) needs about 30% less space, and I've seen over 50% for file systems with source trees in them... -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech
