I regularly used Dropbox for my offsite backup needs, until I purchased an HD camcorder and my data storage requirements increased significantly. I find Dropbox is excellent for syncing files between PC's, but for backup of large amounts of data it is too expensive. Dropbox is not really an offline backup solution anyway, it is really aimed at synchronising files. Apart from the cost, another reason I moved away from dropbox for backup purposes is that if a problem occurred on the Dropbox servers which deleted all my files, this could then sync to both my laptop and PC which would result in me losing everything! So I downgraded to a free Dropbox account and looked around for a new backup solution.
So far my favourite solution is Crashplan. They have clients for all the major OS's including Linux. You can easily backup to an offsite location by just running an instance of Crashplan on a remote PC. If you don't have an always-on offsite machine, then you can use their cloud offering which is remarkably cheap. So far I have only used the free solution of backing up to a remote PC. This works very well. The client automatically determines your external IP address and all your client instances can discover each other via your Crashplan account.
