However, after looking around the forums and (I think) a good search of the wiki, I've yet to come across just how my HDA updates itself. I know how the base installation of F12 updates as I've been using Linux for around 6 years now. Mostly Debian based distros but still, I'm familiar with Linux.
So my question is:
How does my HDA update? By itself via some downstream link via my control panel?
Or,
Do I need to run something similar to 'yum update' in order to get it to update?
Do I or should I run a backup of my installation prior to any updates?
My first installation borked after an update to F12 so I don't want to have to go through another install and setting everything back up due to an incompatible update. BTW, the errors are posted in the 'paste bin' under my username.

Note: I could have easily asked this in IRC but thought here would be better so others would also be able to know to.
