Page "Caches" tab -> click on certain cache container: list of caches in that container is shown.

Having cache configured e.g. line this:

<distributed-cache name="memcachedCache" ...>
    <backups>
        <backup site="BRN" strategy="SYNC"/>
    </backups>
</distributed-cache>

In the UI, when I click Trait > Remote backup filter, the cache is not shown in the results. Truth is that I don't actually have the BRN site running, however, when I look through the jconsole to MBean, the XSiteAdmin bean is there and I'm able to call operations on it, e.g. pushState (of course fails, because I don't have the site there).
