It depends, because old versions of files are kept until the soft  
limit on the account is exceeded. You haven't given sufficient  
information for any meaningful answer.

* How often do the files change on the clients?

* What are the individual limits and usage for the two accounts? (use  
bbstoreaccounts to get this)

For example, if files on the 7G client changed daily and you had a  
100G limit on the corresponding server account, your server could be  
acting as expected.
