<para>If you have placed encryption on your volumes, the encryption will still be in place when
you restore the volume if a UUID encryption key is specified when creating volumes. Using
backup metadata support, UUID keys set up for a volume (or volumes) will remain valid
when you restore a backed-up volume. The restored volume will remain
encrypted, and will be accessible with your credentials.</para>
