Speed up copying large files with ESEUTIL - for large file transfer

18 February,2011 by Jack Vamvas

ESEUTIL is the best tool I've used so far - to copy large files across the network for large file transfer. 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 , if  the file is large the 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
