Copying packages to globally distributed distribution points

Hi Guys,

I need some advice here.

We have central site and a primary site in US and 4 primary sites in 4 other countries.

Each of the primary sites has nearly 20-30 distribution points.

Environment is SCCM 2007 R3 on Windows Server 2003

So far all the packages and images are stored on the central site. Now we want to distribute those packages to all other primary sites and their distribution points then manage everything from the central site.

So here it comes the fun part. I did a test distribution of 10MB file took more than 2 hours. Based on the test it looks impossible to distribute 100GB apps and images to all the DP’S.

So what are my options copying these files to all the sites and DP’s?
