Archive folders with Winrar

In this scenario I would like to backup a folder with documents at a given time. It is important for me to keep older versions of the files.

The batch code for this would look something like:

set rardirectory="C:\Program Files\WinRAR\Rar.exe"
:choice
set /P c=Are you sure you want to continue[Y/N]?
if /I "%c%" EQU "Y" goto :continue
if /I "%c%" EQU "N" goto :leave
goto :choice
:continue

set source="C:\Windows\Web"
set destination="C:\Users\username\Desktop\"
if not exist %destination% mkdir %destination%
echo SOURCE: %source%
echo: DESTINATION: %destination%

echo(
%rardirectory% -dh -r  a -agYYYY-MM-DD-HH-MM-SS %destination% %source% -ep1 -r -m5

This will give you the command line:

C:\Users\fasil\Desktop>set rardirectory="C:\Program Files\WinRAR\Rar.exe"

C:\Users\fasil\Desktop>set /P c=Are you sure you want to continue[Y/N]?
Are you sure you want to continue[Y/N]?

The folder structure should be something like:

backup2019-03-08-22-00-05.rar
├── Web
│   ├── 4K
│   ├── Screen
│   ├── Wallpaper
