Ya he hablado de como migrar datos de un server a otro, he comentado la forma de hacerlo por medio de dos herramientas FSMT y Robocopy (más info…).
Ahora en esta dare un script con el cual se puede hacer una copia diferencial de los datos.
La sintaxis correspondiente seria:
ROBOCOPY
”\\ServerOrigen\E$\FILES” “\\dc02MLM\e$\Privados”
/B /S /E /MIR /R:6 /W:10 /V /NP
/LOG+:Rcpy_Diferencial.log
La opción /B permite copiar archivos en modo backup, /R:X hace X cantidad de retries sobre los archivos ante errores, /W:X es el tiempo de espera entre cada retry. Igualmente hay muchas opciones de esta utilidad, aqui les paso todas las opciones de la versión XP010.
Recordemos que si lo queremos ejecutar en un Windows Vista, Windows 7 o Windows Server 2008, debemos ejecutarlo con permisos de administrador. Requiere elevación.
Espero que les sea util. Saludos, Roberto Di’Lello.

Robocopy esta muy bien pero aun le falta algo, algo que me parece super importante. Posibilidad de copiar solo deltas…
Un saludo
Ricardo, gracias por tu comentario.
Si es verdad, pero bueno igualmente me gusta porque es muy robusto y funciona realmente muy bien, tenes muchas cosas que podes configurar con el robocopy.
Te paso una nota que me gusto sobre el tema: The Coolest Command-Line Tool in Windows Vista http://blogs.msdn.com/tims/archive/2006/09/07/the-coolest-command-line-tool-in-windows-vista.aspx
Saludos.
A ti por responder roberto. Yo lo uso todos los dias para hacer mirror de mis carpetas como parte de mi estrategia de backup. En linux existe rsync que es lo mismo pero con capacidad de copiar solo deltas.
Para los que no les gusta la linea de comandos aqui interfaz grafica para Robocopy http://technet.microsoft.com/en-us/magazine/2006.11.utilityspotlight.aspx
Y aqui una alternativa de Microsoft a Robocopy, Richcopy.. http://technet.microsoft.com/en-us/magazine/2009.04.utilityspotlight.aspx?pr=blog con capacidades de hacer copias en Multithread.
(Ojo en Windows 7 robocopy ya deja hacer multi thread con el switch /MT).
Un saludo,
Ricardo Polo
Great website. Lots of useful information here. I am sending it to some friends ans also sharing in
delicious. And obviously, thanks on your sweat!
Good info. Lucky me I ran across your site by chance
(stumbleupon). I have book marked it for later!
rondibble, excuse my delay in answering but just went out on vacation and my return was somewhat complicated with the times.
I take this opportunity to thank you for participating in the blog and help keep it growing! I ask you to spread it with your friends and colleagues so we can reach more people.
I tell you that there is much material in it. I invite you to see the labs, videos, tutorials, whitepapper. If you want to search for a topic or need help, you have the HELP tab where I explain a bit how to do it, but you have the google search; and the translator for other languages.
Thanks in advance!
