Re: CPY vs FTP

[Tim Bronski <tim.bronski@xxxxxxxxx>]

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.
