RE: Moving large libraries to another system:

The beauty of writing your own versus using FTP is that they probably
wouldn't be near as efficient and thus would take less processor - or is
this an oxymoron?  Maybe it would take more?  Well, maybe more processor
and slower disk access.  If disk is what is beating your machine up maybe
that would help.  Did you run Op's Nav's Management Central to see what
areas are impacted?

We have saved several libraries to save files and then moved them over with
ftp.  We are seeing 40 to 70% compression ratios if you use DTACPR(*YES).
A 3.4gb library compressed down to 2.1gb.  A 1.6gb library compressed down
to .5gb.  The people who do this are quite satisfied with the transfer
rate.  Computers are in the same room.  Both have GB ethernet.  There is a
switch between them.  Faster than tape.

Matt,

It wouldn't be a pleasant task, but you could write transfer programs that
use DDM to read from one machine and write to the other.

I looked in the archives and did not find anything very apparent. I would
appreciate any suggestions:

Without using tape (don't ask), what is the best way to transfer a large
library (40gb) from one system to another? It doesn't have to be fast, but
I need it to not affect the performance of my production system (where I'm
sending from).

I tried FTP, but it ended up slowing the production box. Any help would be
appreciated.
