I would like to backup my important documents online. ( One particular drive or folder )

Any software that automatically backups  the data online.

I don't think there is any software that does this.

Maybe you can find something here:

Here is a link to a list of online storeage and backup sites.   http://lifehacker.com/5064688/online-storage-feature+by+feature-comparison-chart   


Also, here is another online backup service.
https://spideroak.com/   
“Windows/Mac/Linux (All platforms): Online backup utility SpiderOak is notable for its true cross-platform availability, but it also offers (like Mozy) 2 GB of non-expiring free storage space and the ability to run in the background, making persistent backups as you change the contents of any folders you want to watch.”

I have not tried any of them, myself.
