Robocopy - a Unix 'rsync' equivalent
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).Note: this script is not specific to PowerShell. It can be run in command prompt. Robocopy started off as an external program, but is now included in Windows 7 and more modern Windows operating systems.
