If you use automatic backup apps just make sure it's not set to backup "on the fly" as this uses a lot of resources. Personally I use Acronis to do incremental backups of all my data once per day on shutdown. 

setup a windows backup weekly. I do mine to an external usb hd as well as an internal sata 3. Tested the usb drives version of my desktop pc on a laptop and everything there so all good.

In my 20+ years of daily pc usage I have never had a system break on me causing data loss. I still wouldn't go a full week without a backup, unless I hadn't done anything during that time.

I guess I'll stick with how I backup. Others do the same thing I do, but in a different way. Same result. Thanks for the replies.

I have a bunch of small projects, mostly just tests, if I go to C:\Cakewalk Projects, and delete the folder, will it delete the audio as well, because now, I'm not using an external, so want to clean up a little. Will this completely get rid of said projects? Or what do you suggest to remove small projects you no longer want? Thanks!

Windows.SkyDrive or Google.Drive (better - have manual project folder choice): Automatic upload to this service my Sonar X* project folder. 50$ per 1 year for 100 Gb.

Lots of choices - same end result.  Some sort of either automated backup, or some sort of manual routine - doesn't matter, as long as you end up backing things up and rolling off old stuff.

When I was on Windows 7, I used the built-in Windows Backup to run every Monday morning at 3 AM, and it would take incremental backups.

Once I month I would also do a complete backup separately.

With Windows 8, they have changed the backup philosophy, and I haven't set mine up yet, although I will be doing that this evening.  In Windows 8 it no longer backs up all of the system stuff, just data, with the thinking that you would have the OS installation disc to reload that.  There may be more choices there, but that is what I have interpreted thus far in my understanding of this new thinking they have with Windows 8.  (none of this applies to your situation yet, so I will leave my post at that).

To answer Gray36-  
If you have created nothing so far worth keeping then you can do no harm. 

It is a good idea to make your own folders for storing each project and not using any global audio folders etc. Otherwise the good will be mixed with the bad. 

It's no different than managing your photos or any digital files. 
Just put things where YOU want them and don't let the software decide. 

Before you hit record. Do a "save as" for the new song and browse to where you want it to be using windows navigation. Make a new folder and put it in there. 
Check the "copy all Audio with project "   Use CWP for extension.  

Now that folder contains everything to do with that song. It is easy to delete it or move it, or copy it.
