Re: CPY vs FTP

The customer does daily backups of some large libraries that they then send across the country to a development system where they use the data for "testing". To be honest I dont REALLY know what they do with it. So it's a mix of data and objects but the compression is done on the binary save. (They also encrypt it) They then use standard FTP to push it to to a remote site - the FTP is the bottleneck and they have a short window. I did a quick lookup of some stats I have from them....a 25.4G file compressed to 7.2G. It took over 17m to compress - I dont have their machine specs to hand.

Can you please elaborate on "35G daily"?

Is this Iseries stuff? Libs with a mix of data & pgm objects? Or mostly text files?

Are both boxes local? Or over IP long distances?

What is transport & commands used?

SNDNETF? FTP?

Duration?

Thanks!!

maybe compress the file before the transfer ?

This is what I was going to suggest. I must say I don't remember ever
having compressed anything as large as 3.5 GB, but text does compress
very well.
