|
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)!
