zsync is a file transfer program. It allows you to download a file
|
||
|
|
from a remote 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.
|
||
|
|
|
||
|
|
* Client-side rsync - zsync uses the rsync algorithm, but runs it
|
||
|
|
on the client side, thus avoiding the high server load associated
|
||
|
|
with rsync.
|
||
|
|
|
||
|
|
* Rsync over HTTP - zsync provides transfers that are nearly as
|
||
|
|
efficient as rsync -z or cvsup, without the need to run a special
|
||
|
|
server application. All that is needed is an HTTP/1.1-compliant web
|
||
|
|
server. So it works through firewalls and on shared hosting accounts,
|
||
|
|
and gives less security worries.
|
||
|
|
|
||
|
|
* Handling for compressed files - rsync is ineffective on compressed
|
||
|
|
files, unless they are compressed with a patched version of gzip.
|
||
|
|
zsync has special handling for gzipped files, which enables update
|
||
|
|
transfers of files which are distributed in compressed form.
