correlating client save sets with specific paths in the adv filesystem

We back up a lot of our clients to adv filesystems which reside on DataDomain systems. In order to use DataDomain's tools to determine the compression ratio of say a specific client x's save sets, we would need to know where client x's save sets are located within the adv filesystem.

We are using NW 7.2.2 on RHEL 4. I see that we can get the save set ID either from the Instances window or using mminfo, but I can't find anything that maps client ids and/or ssids to specific locations on the adv volume. If I can't do this in 7.2.2, does 7.3.x or 7.4 add this functionality? Or, is there an undocumented "dirty" way that anyone knows of, to get this kind of info?

thanks in advance,

joe
