<h1 class="topictitle1">Save files with referential constraints</h1>
<div><p>Referential constraints link multiple files together in a network, similar
to the network for access paths. You might think of this as a relationship
network. If possible, you should save all the files in a relationship network
in a single save operation.</p>
<p>If you restore files that are in a relationship network during separate
restore operations, the server must verify that the relationships are still
valid and current. You can avoid this process and improve restore performance
if you save and restore relationship networks in a single operation.</p>
<p>The <a href="../books/sc415304.pdf" target="_blank">Backup
and Recovery book</a><img src="wbpdf.gif" alt="Link to PDF" /> has more information about the considerations when restoring relationship
networks.</p>
