I have a little question for You. I manage a little dedicated server with Ubuntu Server 16.04 LTS installed.
I have searched a lot, but I don't found a solid and in first SIMPLE solution for backup my server to another server.
More details: I use Wordpress, Apache, Php, 2 Mysql Databases and SFTP services. Inside there are one domain and one subdomain active.
The question is: I just implemented a backup solution only for my websites contents. But in case the disk will be broken, for example, is there a way to backup all entire server (for example once a month) files and installed program (including the Operational System) and creat a kind of file that I can use to restore all the configurations/files/installed program in another server?
I have no fisic access to the server, and I don't have a Snapshot service avaible with the Hosting (Kimsufi).
I have found this suggest but I can't access to the GRUB: Tar solution.
