Size of NBU 7.5 client

Hi,

In our recent upgrade exercise to 7.5, we have challenges installing the client on older servers who have limited disk space. Compared to 6.X, the 7.5 binary is a lot larger, seems to take almost 4GB. I understand that the unix package includes the binaries for multiple unix platforms, hence one of the reasons for its size. However is it possible to reduce the size needed on the client by deleting the unnecessary platforms?

Thanks.
