After about 10 or 15 minutes, CWM finally finished saving the .android_secure files. This makes sense that it would take longer since almost all my backups and ROMs are on the external SD card. As I understand it, the .android_secure files stores all of the info related to files stored on the ex-SD.
So if you have this problem, check to see if you've got a ton of files/photos/music on the your external SD Card. If you do, your CWM backup will get "stuck" on the .android_secure section for a while. This is normal. Just wait it out and your backup should continue as normal.
