zsync is a file transfer program. It allows you to download a file from
|
|
a remote web server, where you have a copy of an older version of the
|
|
file on your computer already. zsync downloads only the new parts of the
|
|
file. It uses the same algorithm as rsync.
|
|
|
|
zsync does not require any special server software or a shell account on
|
|
the remote system (rsync, in comparison, requires that you have an rsh
|
|
or ssh account, or that the remote system runs rsyncd). Instead, it uses
|
|
a control file - a .zsync file - that describes the file to be
|
|
downloaded and enables zsync to work out which blocks it needs. This
|
|
file can be created by the admin of the web server hosting the download,
|
|
and placed alongside the file to download - it is generated once, then
|
|
any downloaders with zsync can use it. Alternatively, anyone can
|
|
download the file, make a .zsync and provide it to other users (this is
|
|
what I am doing for the moment).
