Do you use cloud storage? If so, I bet you are a Dropbox user. Maybe a Box.com user? A lot of us also use Google Drive, Microsoft's Skydrive and Apple's iCloud. However, we all run into the issue that if we install the clients onto our desktop for these particular services, including all that I have just mentioned, we are forced to use a "default" folder that we have to store everything we want to back up into. Personally, I find this frustrating, and logistically "wrong". These two I am about to mention are personal favorites that not only get the job done, but have one particular feature I LOVE!
