Cloning multiple VPS to a backup server and setting up VPN

There is VPS #1 (fastPanel is installed), on which there are n number of websites, databases, cron jobs, SSL.

There is VPS #2 (FastPanel is installed), on which there are n number of websites, databases, cron jobs, SSL.

There is a clean server that needs to:

1. Configure and optimize as a distribution server (ffmpeg and php 8.1 must be installed for the scripts to work correctly).

2. Install FastPanel to add small websites and databases for a number of small websites.

3. Install Amnezia VPN https://docs.amnezia.org/ru/documentation/instructions/install-vpn-on-server/ and disable log recording for the VPN.

4. Use this server to clone VPS #1 and VPS #1, so that if necessary, I can switch (manual IP change will be needed, automation is not required) traffic from the main VPS to the backup (in case of failure).

As an option, slice the server into:

• VPS #1, VPS #2 - which need to be cloned once a day taking into account all settings (website files, databases, SSL, cron jobs).

• VPS #3 - for separate small websites (those that will work on the server constantly - install FastPanel).

• VPS #4 - for converting and distributing files (File server - there will be quite a large load) with good optimization. FastPanel also needs to be installed on it, so that I can add domains from which the distribution will be performed.

Note:

IMPORTANT! To always have up-to-date files, databases, and settings on the backup server (pull once a day). And in case the database, website, or setting is deleted on VPS #1 or VPS #2, so that all settings are automatically similar on the backup server (that is, a full backup needs to be pulled once a day, old ones cleared, and new data restored).
