How to keep 2 folders in sync using powershell script

Question

We have two folders:

• FolderA: D:\Powershell\Original
• FolderB: D:\Powershell\copy

Now, I want to keep FolderA and FolderB in sync (i.e. when a user changes/adds/removes a file/directory in FolderA then same changes should happen in FolderB).

I tried :

$Date = Get-Date  $Date2Str = $Date.ToString("yyyMMdd")  $Files = gci "D:\Powershell\Original"  ForEach ($File in $Files){         $FileDate = $File.LastWriteTime         $CTDate2Str = $FileDate.ToString("yyyyMMdd")         if ($CTDate2Str -eq $Date2Str) {             copy-item "D:\Powershell\Original" "D:\Powershell\copy" -recurse                -ErrorVariable capturedErrors -ErrorAction SilentlyContinue;          }  } 

But this would require a similar powershell script for deletion of files in FolderA and changes in FolderB.

Answer 1

Have you looked at Robocopy (Robust File Copy)? It can be used with PS and provides what your looking for i.e. it is designed for reliable copying or mirroring of folders (changes/adds/removes) just select the options as required.

Robocopy sourceFolder destinationFolder /MIR /FFT /Z /XA:H /W:5

The /MIR option mirrors the source directory and the destination directory. It will delete files at the destination if they were deleted at the source.
