Disclaimer: I haven't used this.
The focus is Amazon S3, but it seems to work with a bunch of online backup sites.

Seems like a very good price (if online backup is your focus) - monitors files & backs up online.
I've used their Explorer with which you can look at your S3 backups. Has a nice interface, and is easy to use.
They also have software that allows treating S3 as a local drive.
~20 hours to go.
