Something a crazy thought flashed through - if the server owners do not allow downloading the server snapshot, is it possible to pack it into docker somehow? Well, or something similar?
We have a VPS on Hetzner - everything is not bad, but with the backs of a fully configured server, troubles - rsync is long and redundant - but how to pull off the current state ..??
Maybe there is a way to stupidly make an ISO image of the server?
What would then be deployed at home or on our own VPS or locally and just for backup, for example ..
PS often began to visit the thought that if our country is cut off from the global Internet, our entire business will fall due to being physically located over the hill ... Although .. if they cut it off, it will no longer be up to business :)))

as an option, you can remove the image using the veeam linux agent and then download the image. it's even free.

Your task is solvable the way you describe, but it's not the most reliable solution. A more correct way is to use the configuration management system (today the most popular Ansible), and drive everything into it, so that if necessary, take another server, set Ansible on it and get everything that you currently have there. So moving is not terrible, and there is absolutely no point in backing up the server itself, only data is backed up (well, there is a database, application code, user files and other things).

Yes, but this requires support at the FS level.
Creating an image is essentially just packing all the files recorded on the disk, the only problem is that these files do not change during the creation of the image - you need a snapshot of the FS.
This can be done using LVM, or some kind of file system that supports such things.
If it is not possible to create a snapshot - then the image is made only from a disk with which no one is working - you need to stop working.
You can make it easier - take it and set it up manually, set up a backup server from a backup, in the right DC, just to be there when you need to pay and run it.
