Magento var/cache not storing any data

I struggled with an issue that bugged me for a few hours.  I noticed that var/cache was empty!  That was strange..so I did some research and this happened right after I setup apc and memcached.

It turns out the the instructions i followed was saving them into memcached instead of the file system under var/cache

Here is what my app/etc/local.xml looked like:



If this next line was not commented out, it was going to be saved to memcached and NOT the file system

 <!-- backend>memcached</backend -->
