Suggest Free online file storage services for Storing My Important Data

Hi Friends!!!!

I am looking out for a free and reliable online service for storage of my files and other important documents etc. I have Dropbox account but they offer less GB and my need is more than what they offer, so i want something with higher GBs. Also it would be preferred (but not necessary) that it has a desktop integration / sync as dropbox has. Copy the file to a particular location and it is synced to online storage. Something like that.


Looking forward to your suggestion
