I was pointed today at the EVE Online Dev Blog, where they are apparently using zsync as a backup system for repairing incomplete downloads or corrupted files. It sounds like that are not using zsync itself but have probably taken the idea and/or parts of the code and built it into their own repair tool.
It seems like an odd application to me. Incomplete downloads are a rather easy case and do not require the rsync algorithm (there are plenty of HTTP and of course FTP clients that will resume partial downloads). And corrupt files - well I'm surprised if having corrupted parts of files are so common that they have to optimise for it. But I don't know anything more about their problem than is in their blog post. zsync does have the advantage that it combines downloading with verification of what you have, and it does it with minimal work for the central servers (as I guess EVE have the common problem of a high ratio of users to servers).
Happy to see Ubuntu using your technology.I missed that feature for a longtime now. Thanks to you.
