 <h3 id="CVSync">What Is CVSync?</h3>  OpenBSD uses the CVS version control system.
   It is described in more detail <a href="anoncvs.html#CVS">here</a>.
   The <a href="https://man.openbsd.org/cvs">cvs(1)</a> command is used
   to checkout a working tree and perform standard operations (log, diff, etc).
   It can either contact an CVS server (in most cases this will be an OpenBSD
   <a href="anoncvs.html">anoncvs</a> server), or operate against a local
   copy of the repository.
   
 <b>CVSync</b> is a software package for distributing and updating source  
 trees from a master <a href="https://man.openbsd.org/cvs">cvs(1)</a>  
 repository on a remote server host.  
 The OpenBSD sources are maintained in a CVS repository on a central  
 development machine in Canada.  
  With CVSync, OpenBSD users can easily keep their own source trees up to date.  
   
 <p>  <p>
 <b>CVSync</b> uses the so-called pull model of updating. Under the pull  If you would like to operate a local anoncvs server, use cvs(1) commands
 model, each client asks the server for updates, if and when they are  offline, or simply have faster access, you may use CVSync or rsync to

 Thus all updates are instigated by the client.  The server never sends  
 unsolicited updates.  Users must either run the <b>CVSync</b> client  
 manually to get an update, or they must set up a  
 <a href="https://man.openbsd.org/cron">cron(8)</a> job to run it  
 automatically on a regular basis.  
   
 <p>  <h3 id="CVSync">What Is CVSync?</h3>
 The term <b>CVSync</b>, capitalized just so, refers to the entire software  
 package. Its main components are the client <tt>cvsync</tt> which runs on  
 each user's machine, and the server <tt>cvsyncd</tt> which runs at each of  
 the OpenBSD CVSync mirror sites.  
   
   <b>CVSync</b> is a software package specifically used for distributing
   and updating <a href="https://man.openbsd.org/cvs">cvs(1)</a> repositories.
   As it has knowledge of the file format it can operate more efficiently
   than a general-purpose file synchronization program, however it is not
   bug-free and can have problems updating at times.
   
 <p>  <p>
 The OpenBSD Project currently has four main source repositories:  The client <tt>cvsync</tt> runs on each user's machine (typically from
   a <a href="https://man.openbsd.org/cron">cron(8)</a> job), and fetches
   from a server running <tt>cvsyncd</tt>.
   
 <ul>  
   <li><b>src</b> - Houses all source code for the OpenBSD Operating System.</li>  
   <li><b>ports</b> - Houses the <a href="faq/ports/index.html">OpenBSD Ports</a>.</li>  
   <li><b>www</b> - Houses all OpenBSD web pages (including this one).</li>  
   <li><b>xenocara</b> - Houses OpenBSD's active X.org v7 source tree.  
 </ul>  
   
 <h3 id="CVS">What Is CVS?</h3>  
   
 CVS is the source code control system used to manage the OpenBSD source  
 tree.  It is described in more detail <a href="anoncvs.html#CVS">here</a>.  
 Note that CVS and CVSync are entirely different programs.  Although  
 CVS can be used for remote file access, it is not optimized for  
 wholesale source tree distribution over the net, and CVSync can be  
 easily an order of magnitude more efficient for this task.  
   
 <h3 id="starting">Getting Started Using CVSync</h3>  <h3 id="starting">Getting Started Using CVSync</h3>
   
 If you only care about running CVSync, it is recommended that you  
 download the cvsync package from the <a href="ftp.html">ftp mirror  
 sites</a> instead of building your own from the <tt>net/cvsync</tt>  
 port.

   <h3 id="rsync">Getting Started Using Rsync</h3>
   
   Some repository mirrors offer access via rsync, a general-purpose
   file synchronization program.
   Again this should be installed from packages.
   Two flavours are available:
   
   <pre>
           <b># pkg_add rsync</b>
           Ambiguous: choose package for rsync
           a       0: <None>
                   1: rsync-3.1.2p0
                   2: rsync-3.1.2p0-iconv
           Your choice:
   </pre>
   
   Unless you have other requirements, simply install the standard version
   (option 1 on the list above).
   You can select the flavour on the command-line to avoid
   <a href="//man.openbsd.org/pkg_add">pkg_add(1)</a> prompting for the
   version like so:
   <pre>
           <b>pkg_add rsync--</b>
   </pre>
   
   In order to mirror the OpenBSD repository with rsync,
   the following command line might be used:
   
   <pre>
           <b>rsync -avz --delete rsync://obsdacvs.cs.toronto.edu/obsdcvs/ /cvs/</b>
   </pre>
