|
|
<div><p>This topic describes what to do in the event that you need to use
|
|
backup copies if you lose information on your system.</p>
|
|
<div class="section"><p>Computers in general, and the IBM<sup>®</sup> eServer™ iSeries™ server in particular, are very
|
|
reliable. You might run your system for months or even years without experiencing
|
|
any problems that cause you to lose information on your system. However,
|
|
as the frequency of computer problems has decreased, the potential impact
|
|
of problems has increased. Businesses are more and more dependent on computers
|
|
and the information that is stored in them. The information that is in your
|
|
computer might not be available anywhere else.</p>
|
|
<p>Saving the information
|
|
on your system is time-consuming and requires discipline. Why should you
|
|
do it? Why should you spend time planning and evaluating it?</p>
|
|
<p>Because
|
|
you might have a problem. You will need to use your backup copies of information.
|
|
Every system needs to restore some or all of its information at some point
|
|
in time. </p>
|
|
<p>The Backup and recovery timeline provides a high level overview
|
|
of the events that occur during the backup and recovery process.</p>
|
|
<p>After
|
|
you study the backup and recovery timeline, you are ready to start planning
|
|
your strategy. Follow these steps:</p>
|
|
</div>
|
|
<ol><li><span>Know what to save and how often to save it.</span></li>
|
|
<li><span>Find your save window.</span></li>
|
|
<li><span>Choose availability options.</span></li>
|
|
<li><span>Test your strategy.</span></li>
|
|
</ol>
|
|
<div class="section"> <p>You might also find the Plan disaster recovery useful as a planning
|
|
resource.</p>
|
|
<p>This topic contains information about how to plan your strategy
|
|
and make the choices you need to make as you set your system up for backup,
|
|
recovery, and availability. For information about how to perform the tasks
|
|
that are related to these topics, see <a href="../books/sc415304.pdf" target="_blank">Backup and Recovery</a><img src="wbpdf.gif" alt="Link to PDF" /> and the Back up your server topic. The Availability <span>roadmap
|
|
provides</span> information about the common types of failure that can occur.</p>

<li class="ulchildlink"><strong><a href="rzaj1timeline.htm">Backup and recovery timeline</a></strong><br />
|
|
The timeline for backup and recovery begins when you save information, and ends when your system is fully recovered after a failure.</li>
|
|
<li class="ulchildlink"><strong><a href="rzaj1whattosave.htm">Know what to save and how often to save it</a></strong><br />
|
|
You should save everything in your system as often as possible.</li>
|
|
<li class="ulchildlink"><strong><a href="rzaj1savewindow.htm">Find your save window</a></strong><br />
|
|
When you run save procedures, how you run save procedures and what you save depend on the size of your save window.</li>
|
|
<li class="ulchildlink"><strong><a href="rzaj1availopt.htm">Choose availability options</a></strong><br />
|
|
Availability options are a complement to a good save strategy, not a replacement.</li>
|
|
<li class="ulchildlink"><strong><a href="rzaj1teststrat.htm">Test your strategy</a></strong><br />
|
|
If your situation requires a medium save strategy or a complex save strategy, it requires regular review.</li>
|
|
<li class="ulchildlink"><strong><a href="rzaj1sampleplan.htm">Plan disaster recovery</a></strong><br />

This topic provides you with guidelines for the information and procedures that you need to recover from a disaster.</li>
