How to make a duplicate of the bitrix site?

Question

JavaScript

Hello. Can you please tell me how to make a duplicate of the bitrix site? I have never worked with Bitrix(
In google they write differently everywhere, and I'm already confused(
I need to make a site for example "a2", which is similar to the site "a1", only the design changes a little bit (background color, and main picture).
I understand correctly, you need to do
-backup (already done, the site weighs 1.4 GB, is that normal?)
-create a new database,
-deploy on a server
That is, you don't need to buy an additional license, you buy a license key and change it on the site?

Answer 1

it is not entirely clear what needs to be done to
compose the text of the message from the data?
like this for example

vk.updates.hear(/^(?:СП Топ-10)$/i, async (context) => { 
  axios.get(`https://minecraft-statistic.net/api/server/info/145.239.133.118_25565`).then(res => {
    let message = ''; 
    res.data.sort((a, b) => a.place - b.place);
    res.data.forEach((item) => {
      message += item.nickname + ' - Место ' + item.place + '\n';
    });
    context.send(message);
  });
});

Answer 2

Deploy the copy using the restore.php script, otherwise everything is described correctly.
this is normal
License and license key in this context are the same
