ok... lets keep it simple.
Get an External Drive, like:
http://www.newegg.com/Product/Product.aspx?Item=N82E16822178434
Get GoodSync ($30 for 1 license) http://www.goodsync.com/
Plug in the backup drive
Load and license GoodSync
Create a new Backup Job. Click the Left Browse, select your user name from the list and OK
Click the Right Browse and select the external drive you just plugged in, Click New Folder, name it My Stuff (or something) click OK 2x
Now Click Analyze, then once done Click Sync.
Once the first run is complete, Goto (top line menu) Tool / Program Options and set "Start GoodSync when Windows starts" then click OK
Right click on the Job Name and select Options, Uncheck "Propogate Deletions" goto Auto, set it to Periodically (check both boxes) and time every 2 hours and some odd minutes. Goto Advanced and check Fast Pre-Analyze... then click OK.
Now... Do NOT leave that external plugged in all the time. It will result in premature failure of it. Once a week or 2, when you are on the machine just plug it in while you are on the computer and leave it until you are done for the day, ewhen you shut down, unplug it and put is away.
Tada... backup!!! also this way the backup will have aven old crap you deleted on it "just in case"... The files are in the same location as you would find them if you went to c:\user\YOU\... and looked for them.
