Idea for an enterprising entrepreneur: create an app that does a multi-site/format backup. You decide which folders/file-pattern go to the cloud i.e. Dropbox and which go to your external HD. I have almost 300GB of videos and pictures of the kids that I don't want backed up to the cloud (too expensive and too time consuming). However I also have ~500MB of text files, word docs, tax forms (pdf's printed from Turbotax online) that would be perfect to backup to the cloud since that wouldn't take any time at all. Then this software would automate this so that anytime I add new pictures/videos, it would automatically go to the external HD. Anytime I create/update a word doc it automatically gets uploaded/synced to Dropbox. Perhaps the backup software could watch certain folders and automate the backups for me so I don't even have to think about it. Heck I might even pick-up C# and learn me some Windows programming.
