echo  What it does:
echo  --------------
echo  Uses robocopy (built into Windows) to copy ALL files
echo  recursively from your source folder to a new timestamped
echo  subfolder at your destination.
echo.
echo  Folder name format:
echo    BACKUP_YYYYMMDD_HHMMSS
echo    Example: BACKUP_20250318_143022
echo.
echo  robocopy flags used:
echo    /e      Copy all subdirectories (including empty ones)
echo    /r:3    Retry 3 times if a file is locked
echo    /w:5    Wait 5 seconds between retries
echo    /tee    Output to both screen and log file
echo    /np     No progress percentage (cleaner output)
echo    /log    Save full log to backup folder
echo.
echo  What is NOT backed up:
echo    - Files currently locked by another process
echo    - Files you don't have read permission to
echo.
echo  How to restore:
echo    Simply copy files from BACKUP_... back to original location.
echo    No special tool needed.
