ESEUTIL is the best tool I've used so far - to copy large files across the network.
By "large file" I mean at least 50 GB.
I found the tool on our Exchange Server installation - where it's used for defragmentation
Normally , if using COPY , Buffered I\O uses Paged Pool - so , the larger the file there is a greater chance resources will be consumed - to the point of a COPY failing.
ESEUTIL avoids this process, and uses Unbuffered I\O
Using ESEUTIL I've been able to halve a 95 GB file transfer
The syntax is :
ESEUTIL /Y \\myserver1\f$\mydb.bak /D \\myserver2\f$\mydb.bak
