Any machine that has 3.7TB worth of files is *begging* to be broken up
into multiple node names, each node responsible for backing up a portion
of a physical machine. Particularly if you're using slow tape technology
like DLT.

Exports have been notoriously slow to write (and read) from ADSM/TSM
first iteration. (This is one reason why you can now export directly
from one TSM server to another.) Did you perform a MOVE NODEDATA prior
to the export? If you didn't, and the node is not collocated, you made
your life far harder than it had to be.
