+Host System Administration
+--------------------------
+
+`Proxmox Backup`_ is based on the famous Debian_ Linux
+distribution. That means that you have access to the whole world of
+Debian packages, and the base system is well documented. The `Debian
+Administrator's Handbook`_ is available online, and provides a
+comprehensive introduction to the Debian operating system.
+
+A standard `Proxmox Backup`_ installation uses the default
+repositories from Debian, so you get bug fixes and security updates
+through that channel. In addition, we provide our own package
+repository to roll out all Proxmox related packages. This includes
+updates to some Debian packages when necessary.
+
+We also deliver a specially optimized Linux kernel, where we enable
+all required virtualization and container features. That kernel
+includes drivers for ZFS_, and several hardware drivers. For example,
+we ship Intel network card drivers to support their newest hardware.
+
+The following sections will concentrate on backup related topics. They
+either explain things which are different on `Proxmox Backup`_, or
+tasks which are commonly used on `Proxmox Backup`_. For other topics,
+please refer to the standard Debian documentation.
