Norton Online Backup 2.0 Set Limits?

I have been using Norton Ghost for years with few problems, so when Norton Online Backup 2.0 came out, I thought I would give it a try.

 

The problem I am having is that it appears to have no set limits. In Norton Ghost you can set it to automatically delete older versions so that you don't run out of space. With Norton Online Backup 2.0 it appears that you have to periodically go online and manually delete older versions; or am I missing something? Thanks for the advice.
