There was a bug in 7.1.2 client for Windows that caused something like this.
Your saveset completion reports would report lots of access is denied if that
is the problem.
 
Not sure if the bug carried over to 7.2 but  upgrading to 7.2.1 fixed it.

        Subject: [Networker] Stops backing up directories at 4th level
        
        

        Legato 7.2 

        Have faithfully been doing backups, then went to do a restore. 

        What I found was not good, Legato seems to stop backing directories
up 
        after the 4th level of directory. 

        Saveset = All for client. 

        No server based or client based directives.
