<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>
