It allows you to download a file\nfrom a remote server, where you have a copy of an older version of\nthe file on your computer already. zsync downloads only the new\nparts of the file.\n\n* Client-side rsync - zsync uses the rsync algorithm, but runs it\non the client side, thus avoiding the high server load associated\nwith rsync.\n\n* Rsync over HTTP - zsync provides transfers that are nearly as\nefficient as rsync -z or cvsup, without the need to run a special\nserver application. All that is needed is an HTTP/1.1-compliant web\nserver. So it works through firewalls and on shared hosting accounts,\nand gives less security worries.\n\n* Handling for compressed files - rsync is ineffective on compressed\nfiles, unless they are compressed with a patched version of gzip.\nzsync has special handling for gzipped files, which enables update\ntransfers of files which are distributed in compressed form.\n","package_architecture":"amd64","stem":"zsync","readme":null,"dependencies":[{"path":"devel/metaauto","type":"build","package_spec":"","url":"/packages/release/devel/metaauto/"},{"path":"devel/autoconf/2.65","type":"build","package_spec":"","url":"/packages/release/devel/autoconf/2.65/"},{"path":"archivers/bzip2","type":"build","package_spec":"","url":"/packages/release/archivers/bzip2/"}],"reverse_dependencies":{"count":0,"url":null},"categories":["net"],"flavors":[],"only_for_architectures":[],"not_for_architectures":[]}}
