Cisco NCS: "Twice" The Space Needed

One of the things I have learned here lately, is that when you want to backup your config for your Cisco wireless NCS server, you have to have "twice" the space of your config free on your partition.  This is somewhat of a bummer if you have a large config.  As you can see below, this one is sitting at 77% used space, which does not work for us.  We will have to delete some files for sure.
