RE: CPY vs FTP



fixed

Thanks for the info. Could you comment on the duration for the FTP bottleneck? Is this a few hours? Or many hours?

Thanks

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.

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.
