Commands tagged zsync (1)

  • Zsync is an implementation of rsync over HTTP that allows updating of files from a remote Web server without requiring a full download. For example, if you already have a Debian alpha, beta or RC copy downloaded, zsync can just download the updated bits of the new release of the file from the server. This requires the distributor of the file to have created a zsync build control file (using zsyncmake).
