Here is how: I had Fedora Core 3 CD1, 2, 3 and 4 iso files, and I knew the Fedora Core 3 DVD iso file is mostly made up of those files in CD iso files. I created an iso image of all the contents of those 4 iso files and then using rsync I sync'ed against an rsync server. Rather than downloading (in case of ftp and http etc.) 2+ GB of data, rsync managed to do it all in just under 40 MB and just in few minutes (rather than few hours in case http, ftp etc.). That is great! Unbelivable! Thank you for your great work! Hari. PS: It seems rsync is not quite good at saving bandwidth in case of bzip2 compressed files (like rpm etc.). It ought to be a known fact. Find local movie times and trailers on Yahoo! Movies. http://au.movies.yahoo.com
