.SYNOPSIS
|
|
Sync two dirs
|
|
.DESCRIPTION
|
|
This PowerShell script synchronizes (mirrors) the content of 2 directory trees by using Robocopy.
|
|
Typical use cases are backups: at first everything is copied (full backup), afterward only changes are copied (incremental backup).
|
|
IMPORTANT NOTE: Make sure the target path is correct because the content gets replaced (DATA LOSS)!
|
|
.PARAMETER sourcePath
|
|
Specifies the path to the source dir (to be entered by default)
|
|
.PARAMETER targetPath
|
|
Specifies the path to the target dir (to be entered by default)
|
|
.EXAMPLE
|
|
PS> ./sync-dir.ps1 C:\Photos D:\Backups\Photos
