The script below copies data from FileServ1 to FileServ2, the destination holds 
a full mirror along with file security info. When run regularly to synchronize 
the source and destination, robocopy will only copy those files that have 
changed (change in time stamp or size.)

--------------------------------------------------------------- 
@ECHO OFF
 SETLOCAL
 
SET _source=\\FileServ1\e$\users
 
SET _dest=\\FileServ2\e$\BackupUsers
 
SET _what=/COPYALL /B /SEC /MIR
 :: /COPYALL :: COPY ALL file info
 :: /B :: copy files in Backup mode. 
:: /SEC :: copy files with SECurity
 :: /MIR :: MIRror a directory tree 

SET _options=/R:0 /W:0 /LOG:MyLogfile.txt /NFL /NDL
 :: /R:n :: number of Retries
 :: /W:n :: Wait time between retries
 :: /LOG :: Output log file
 :: /NFL :: No file logging
 :: /NDL :: No dir logging
 
ROBOCOPY %_source% %_dest% %_what% %_options%
---------------------------------------------------------------

You can start this script today if you want and stop it whenever you want.
When you run it the next 2 weeks on a daily basis the servers will be in sync as
soon as you want to take the new server into production.

Jeroen
