That is fastboot, don't panic. Not sure why it didn't reboot into recovery though. Try trying into recovery and doing the backup from there.
EDIT: wait, with the red triangle it's not fastboot. Anyway, try going straight to recovery like I said.
also make sure you have the correct version of clockworkmod installed. i thought i read that happens sometimes when you have the gsm version instead of the cdma version (or vice versa). the cdma version should be 5.5.0.4 (and i think gsm is 5.5.0.2).
someone correct me if i'm wrong.
