<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 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>

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 />

<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>
