Hi kelly,
         I used 3.1.0.6 of Digital unix client.

Digital UNIX V4.0D  (Rev. 878).

I have used the default settings and have faced no such problems of files
not getting g backed up. I have however for insurance put (Subdir yes)   in
dsm.opt.

But it does look like you are running out of buffer space for some reason.
Omit out the TCPbuffsize etc and try it out again.


Sincere Regards

Sri
