<h3 class="section">2.9 Synchronising Databases</h3>

<p>With Jim&rsquo;s server preparations done, now Abe is ready to fetch Jim&rsquo;s
code. To do this he issues the monotone <code>sync</code> command:
</p>
<div class="smallexample">
<pre class="smallexample">$ mtn --db=abe.mtn sync &quot;mtn://jim-laptop.juicebot.co.jp?jp.co.juicebot.jb7*&quot;
mtn: connecting to mtn://jim-laptop.juicebot.co.jp
mtn: first time connecting to server mtn://jim-laptop.juicebot.co.jp
mtn: I'll assume it's really them, but you might want to double-check
mtn: their key's fingerprint: 9e9e9ef1d515ad58bfaa5cf282b4a872d8fda00c
mtn: warning: saving public key for jim@juicebot.co.jp to database
mtn: finding items to synchronize:
mtn: bytes in | bytes out | revs in | revs out | revs written
mtn:     2587 |      1025 |       1 |        0 |            1
mtn: successful exchange with mtn://jim-laptop.juicebot.co.jp
</pre></div>

<p>Abe now has, in his database, a copy of everything Jim put in the
branch. Therefore Abe can disconnect from the expensive network
connection he&rsquo;s on and work locally for a while. Remember that, in
monotone, work is done between workspaces in the filesystem and
the local database; network connectivity is necessary only when that
work is to be shared with others.
</p>
<p>As we follow the juicebot team through the next several steps, we&rsquo;ll see
them run the <code>sync</code> command again with Jim, and work will flow
both ways. The first time you <code>sync</code> a new database, monotone
remembers the server and branch patterns you use, and makes them the
default for future operations.
</p>
<p>At the end of each exchange, information about all changes in the branch
known to each database have been sent to the other party - including the
work of the third team member that had previously been exchanged. As
well as allowing each team member to learn about the others&rsquo; work, this
also means that each party&rsquo;s laptop contains a <em>backup</em> of the
others&rsquo; work too.
</p>
<p>Jim, Abe and Beth will continue working like this while they&rsquo;re getting
started, and we&rsquo;ll revisit the issue of network service with them a
little later as the project grows.
