I may need to rebuild a 1TB Windows 2008 DFS replication folder between our UK and USA sites. It's good practise to seed the other copy before starting replication so that the bulk of the data doesn't need to be replicated during the initial replication.
However, I've never been sure whether this seed needs the security (access control lists) with the seed or whether you can use a simple copy of the files?
In the past we've used robocopy to external USB (which somebody took out with them) with the /sec flag which copies security but this has caused a few headaches when copying the data back off.
