How to make an ISO image from a configured VPS server?

Question

Backup

Hello.
I rent a VPS server. I configured everything on it as I needed and added a couple of sites.
How can I make it an ISO image so that I can download it, for example, from another provider and get exactly the same server , with all the settings, packages, sites, OS, etc.?
Do I understand correctly that VPS providers allow you to upload their ISO image specifically for such cases?
Is this possible and are there more convenient ways to copy the entire system?

Answer 1

Use MondoRescue A
utility specially designed for server backup and cloning. It's free, open source, and makes it easy to create a complete copy of an entire Linux server in ISO format on CD, DVD, USB, HDD, or NFS. It also allows you to quickly restore this copy to your server. If necessary, you can choose to restore only individual files. The main advantage of this system is its ease of use, you can create a full backup of the server without interrupting its operation.

Answer 2

The ability to connect an image is required for self-installation of the OS from it via VNC.
Data transfer 1:1 is theoretically possible, but only with the assistance of both hosts.
