In the modern world, creating a website for yourself is not difficult. And it seems that you just need to choose a hosting, install a site, fill it, and this will be the end of the process.
But in fact, it is critically important to set up backups for your site. After all, in this world, everything is eternal. Anything can happen on your server (fire, hardware breakdown, hard disk wear), and if you don't think about the site backup in a timely manner, then this will most likely lead to a complete failure.
But what should be done? Just create site backups, and the more often you do it, the better.
To create a backup, you may need some very different tricks. For example, you can manually download all the files of your site to your local computer. Alternatively, you can copy the data to another server on the Internet (many providers provide a similar service).
However, remember that it is necessary to approach the site backup competently and efficiently. That is, you must be able to do it. If you have never made a backup for your site before, then you need to go online and see instructions on how to create a backup for the site (for example, if you have a wordpress engine, then backups can be created using special plugins in automatic mode), and etc.
Remember that by making backups, you protect yourself, your nerves and your site from various unknown incidents!
