It sounds to me like they need a switch so you can change the behavior
of the "All" saveset specifier so you can set whether it picks up NFS
and/or SMB mounts.

That is just ridiculous. Someone in EMC needs shooting for that. That
means that the default behaviour is to backup potentially large
filesystems multiple times over a network connection. Worse still, it is
difficult and clumsy to suppress this default behaviour, whereas it is
quite simple the other way round. What versions are you referring to
Preston?

It wouldn't surprise me either but it would severely disappoint me. I
really hope this hasn't happened. Alex, what version are you using and I
will add it to my growing list of versions to avoid at all costs.

It does seem that since Legato became EMC there have been a number of
poor decisions regarding the development of the product and also
regarding the way it is packaged.
