  rsync
rsync is freely available under the GNU General Public License version 2 and is currently being maintained by Wayne Davison.
The problem with rsync hanging at the end of the transfer on Cygwin had been previously traced to a signal-handling bug in their compatibility DLL.
Rsync version 2.5.6 and earlier contains a heap overflow vulnerability that could be used to remotely run arbitrary code, but this only affects the use of rsync as an "rsync daemon" (where rsync handles incoming socket connections, typically on port 873).

 Rsync - Wikipedia, the free encyclopedia
In the latter case, the rsync client executable must be installed on the near as well as the far host (the computer running the remote shell daemon).
The rsync utility uses an algorithm (invented by Australian computer programmer Andrew Tridgell) for efficiently transmitting a structure (such as a file) across a communications link when the receiving computer already has a different version of the same structure.
The rolling checksum used in rsync is based on Mark Adler's adler-32 checksum, which is used in zlib, and which itself is based on Fletcher's checksum.

 OSXFAQ - Technical News and Support for Mac OS X
rsync is a program that behaves in much the same way that rcp does, but has many more options and uses the rsync remote-update protocol to greatly speedup file transfers when the destination file already exists.
Using rsync in this way is the same as using it with rsh or ssh except that: to separate the hostname from the path.
Current versions of rsync actually use an adaptive algorithm for the checksum length by default, using a 16 byte file checksum to determine if a 2nd pass is required with a longer block checksum.

 rsync
rsync is a program that behaves in much the same way that rcp does, but has many more options and uses the rsync remote-update protocol to greatly speed up file transfers when the destination file already exists.
Perhaps the best way to explain the syntax is some examples: rsync *.c foo:src/ this would transfer all files matching the pattern *.c from the current directory to the directory src on the machine foo.
Using rsync in this way is the same as using it with rsh or ssh except that: # you use a double colon :: instead of a single colon to separate the hostname from the path.

 man: rsync   (Site not responding. Last check: 2007-10-21)
rsync is a program that behaves in much the same way that rcp does, but has many more options and uses the rsync remote-update protocol to greatly speed up file transfers when the destination file is being updated.
The rsync version used on all destinations must be at least as new as the one used to generate the batch file.
Rsync will die with an error if the protocol version in the batch file is too new for the batch- reading rsync to handle.

 Linux.com | Backing up your Linux desktop with rsync
Rsync is a command line utility traditionally used in synchronizing files between two computers, but rsync can also be used as an effective backup tool.
Rsync preserves files found in the target and not in the source by default, allowing for multiple sources to be added to a single target destination.
Rsync is a very powerful tool, and you should pat yourself on the back for applying some of its potential.

 Mike's Mac OS X Management Software and Tips: How to Setup rsync for Remote Synchronizations
rsync allows you to synchronize files between folders locally on a machine or on two machines on a network.
If you want to use rsync in an automated shell script (which is what I will be describing), I recommend that you create an SSH key without a passphrase.
It is necessary to copy this file on the client to allow rsync to run in local mode (synchronizing directories on the local machine to directories also on the local machine).

 Installing rsync on a windows machine
My version of rsync+ssh is a very stock-standard rsync, with the cygwin1.dll (currently version 1.3.6-6), and a simplified version of ssh.
Note that the cygwin source is a completely unaltered version 1.3.6-6, and the rsync sources are also completely clean.
Including and excluding files and directories is well described in the rsync man page.

 freshmeat.net: Project details for rsync
rsync is a replacement for rcp (and scp) that has many more features.
It does this by sending just the differences in the files across the link, without requiring that both sets of files are present at one of the ends of the link beforehand.
I use rsync exclusively, called from python and ruby scripts which handle mirrored and standardized directory structures across the sites, in other word the sites and dev dirs are all to the same pattern.

This tells rsync to recreate symbolic links on the remote system to be the same as the local system.
This option causes rsync to update the remote owner of the file to be the same as the local owner.
This option causes rsync to update the remote group of the file to be the same as the local group.

 Rsync for NetWare - rsync
RSYNC is an open source utility under a GNU-style license that has been ported to NetWare® and that is being used in the Nterprise Branch Office, the Novell soft appliance.
It will be hosted here on forge while we work with the Rsync team to put it into the source code.
I used some of the test scripts submitted by users to test this version, so hopefully this will be able to handle more of the real-world options.

 Easy Automated Snapshot-Style Backups with Rsync   (Site not responding. Last check: 2007-10-21)
rsync program, which is installed by default on most Linux distributions.
Rsync's specialty is efficiently synchronizing file trees across a network, but it works fine on a single machine too.
A: In rsync, transfers are done to a temporary file, which is cut over atomically, so the transfer either happens in its entirety or not at all.

 LWN: Remotely exploitable heap overflow in rsync
rsync 2.5.6 security advisory ----------------------------- December 4th 2003 Background ---------- The rsync team has received evidence that a vulnerability in rsync was recently used in combination with a Linux kernel vulnerability to compromise the security of a public rsync server.
While the forensic evidence we have is incomplete, we have pieced together the most likely way that this attack was conducted and we are releasing this advisory as a result of our investigations to date.
To see if you are running a rsync server you should use the netstat command to see if you are listening on TCP port 873.

 Rsync
rsync is a replacement for rcp that has many more features.
rsync uses the "rsync algorithm" which provides a very fast method for bringing remote files into sync by sending just the differences in the files across the link, without requiring that both sets of files are present at one of the ends of the link beforehand.
A technical report describing the rsync algorithm is included with this package.

 Gentoo Linux Documentation -- Gentoo Linux rsync Mirrors Policy and Guide   (Site not responding. Last check: 2007-10-21)
There are three kinds of Gentoo rsync mirrors: main rotation mirrors, community mirrors and private mirrors.
Users are welcome to use our regular mirror system to establish a private rsync mirror, though they are asked to follow certain basic rsync etiquette guidelines.
To try and prevent this, you may use the this perl script which will scan your rsync log files, pick out IP addresses that have already connected more than N times that day and dynamically create a rsyncd.conf file, including the offending IP addresses in the 'hosts deny' directive.

RsyncX is an implementation of rsync with HFS+ support and configuration through a command line (Terminal) or graphical user interface.
This release will not overwrite the existing version of rsync, and is completely compatible with all versions of rsync within the 2.6.0 protocol accepted range.
For best results, this version of rsync should be installed on to all machines that will be involved in the rsync process.

 Mini-HOWTO: Fixing rsync on Tiger (Mac OS X 10.4.x)
When used with the --delete option, the rsync receiver will try to unlink the (fake) synthetic files, flooding the syslog with failure reports, possibly filling the entire boot disk.
With rsync installed in Server mode (see the man pages) on a Mac mini, a no-changes full filesystem 'incremental' backup takes 45 minutes over Airport Extreme (and less over Ethernet), during which both machines are still mostly responsive.
Using the same patched rsync source on Linux, I have backed up my entire OS X boot disk to a Linux server, then restored the files from the Linux server to a FireWire drive connected to my Mac.

 mezzoblue  §  Web Server Backup
It's great to see more people plugging into rsync and how excellent it is. One thing I haven't been able to figure out is how to do an rsync operation like this, but add in stuff that should be skipped and *not* backed up.
If you are put off by the lack of feedback as rsync is working you can add the "--progress" option on the command line (note that it can't appear between the "e" and the "ssh").
Again, I don't know if rsync does this, but the added benefit with version control is that you can revert your entire directory and all of its files to a previous state if the need arises.

 Rsync for Windows :: Gaztronics.net
If you are planning to use this method to back-up Windows based systems via the Internet it is advisable to research the use of SSH before you start.
See here for a useful guide to using Rsync with stunnel.
Setting up Rsync as a Server under Windows is a little more tricky, due to the differences in security and paths; and the inability to use the 'authenticate user' mode of Rsync.

Some, such as wget and rsync, are full of useful capabilities for those brave enough to read their man pages and experiment.
Another time these can be useful is when you really don't care if someone is listening: for example, when setting up a mirror for a publicly accessible web or FTP site, or keeping a directory's contents synchronized with such a site.
Many of these programs can handle more than just FTP connections, and some even have their own shell-like syntax for sophisticated use.
