Robocopy, or “Robust File Copy”, is a command-line directory and/or file replication command. Robocopy functionally replaces Xcopy, with more options. It has been available as part of the Windows Resource Kit starting with Windows NT 4.0, and was first introduced as a standard feature in Windows Vista and Windows Server 2008. The command is robocopy
This is one of the utilities I cannot live without. It makes sure that the contents of <Source> folder are the same as the contents of the <Destination> folder. So it’s a tool to synchronise 2 folders. There are of course options to copy files incrementally and make destination folder have all the files that were in the source folder.
It’s one of the best tools out there for backing up data. It has trillion number of commands – http://www.computerhope.com/robocopy.htm
There are also a plethory of forks, https://betterrobocopygui.codeplex.com/ being one.
I personally use it it for backing up user profile data to dropbox: robocopy C:\Users F:\Dropbox\Profiles /MIR /v /R:0 /W:0
This command is scripted in a file and scheduled to execute periodically.
I say it’s a must have tool for everyone and you can get a copy of it from http://www.microsoft.com/en-gb/download/details.aspx?id=17657
