Description

Copy files from a file server to a NetApp CIFS server using Robocopy to retain Windows permissions.

Procedure

  • Robocopy allows users to retain Windows file permissions when copying to a filer.
    • To copy files from a Windows server to a NetApp filer, use the following command syntax:
    • robocopy source destination /S /SEC
  • To retain the current ownership setting of the files being copied/moved, the CopyFlag "O" needs to be used with ROBOCOPY command. 
    • The copy option "/copyall" is equivalent to "/copy:DATSOU", so it includes the CopyFlag "O", but you can also use custom copy flags using the "/copy:" option, followed by the desired CopyFlags as described here.
    • robocopy /S /COPYALL
    • robocopy /S /COPY:DATSO
  • To keep the data in sync during a pilot phase of a migration, you can also put the following into a script and schedule it to run each hour on the Windows source server:

robocopy <sourcedir> <destinationdir> /copyall /mir /zb /r:1 /w:3
