<h1 class="topictitle1">Determine which data should be made resilient</h1>
<div><p>Understand what types of data you should consider making resilient.</p>
<p>Determining which data you need to make resilient is similar to determining
which kind of data you need to backup and save when you prepare a back up
and recovery strategy for your systems. You need to determine which data in
your environment is critical to keeping your business up and running.</p>
<p>For example, if you are running a business on the Web, your critical data
may be:</p>
<ul><li>Today's orders</li>
<li>Inventory</li>
<li>Customer records</li>
</ul>
<p>In general, information that does not change often or that you do not need
to use on a daily basis probably does not need to be made resilient.</p>
