<dd>Whether the application allows its data to be backed up through the Android

Backup Manager — "{@code true}" if it does, "{@code false}" if not.  By

default this attribute is "{@code true}".  If an application declares this

attribute to be "{@code false}" the Backup Manager will never attempt to

perform any backup or restore operation, even if the application declares a

valid <a href="#agent">{@code android:backupAgent}</a> attribute in its

manifest.
