.SYNOPSIS .SYNOPSIS
Sync's two folders Syncronizes two folders
.DESCRIPTION .DESCRIPTION
This PowerShell script synchronizes two folders via Robocopy (useful for e.g. backups). This PowerShell script synchronizes (mirrors) the content of 2 directory trees by using Robocopy.
NOTE: Make sure the target folder is correct because the content gets replaced! Typical use cases are backups: at first everything is copied (full backup), afterward only changes are copied (incremental backup).
.PARAMETER Source IMPORTANT NOTE: Make sure the target path is correct because the content gets replaced (DATA LOSS)!
Path to the source folder .PARAMETER sourcePath
.PARAMETER Destination Specifies the path to the source folder
Path to the destination folder .PARAMETER targetPath
Specifies the path to the target folder
.EXAMPLE .EXAMPLE
sync-folder -source C:\Folder01 -destination C:\Folder02 PS> ./sync-folder.ps1 C:\MyPhotos D:\Backups\MyPhotos
