<blockquote>
<div><ul>
<li><p class="first">An old archive system contains data from 1990-01-01 to 1995-07-12.</p>
</li>
<li><p class="first">This data needs to be copied to a new archive system.</p>
</li>
<li><p class="first">The data needs to be processed before it is written to the new archive system.</p>
</li>
<li><dl class="first docutils">
<dt>There are several types of data to be back-archived.</dt>
<dd><ul class="first last simple">
<li>Analysis</li>
<li>Forecast</li>
<li>Climatology</li>
<li>Observations</li>
<li>Satellite images</li>
</ul>
</dd>
</dl>
</li>
<li><p class="first">These data types can be copied independently.</p>
</li>
<li><p class="first">The data is organised daily in the old archive. The system should copy one day of data at a time.</p>

<p><strong>What to do:</strong></p>
<ol class="arabic simple">
<li>Write the <a class="reference internal" href="/wiki/display/ECFLOW/Glossary#term-suite-definition"><em class="xref std std-term">suite definition</em></a></li>
<li>Design it so new data types can be easily added with their own periods</li>
