What is Proxmox Backup Server?
------------------------------
-Proxmox Backup Server is an enterprise-class, client-server backup software
-package that backs up :term:`virtual machine`\ s, :term:`container`\ s, and
-physical hosts. It is specially optimized for the `Proxmox Virtual Environment`_
-platform and allows you to back up your data securely, even between remote
-sites, providing easy management with a web-based user interface.

Proxmox Backup uses state of the art cryptography for both client-server
communication and backup content :ref:`encryption <client_encryption>`. All
backup data and provides an API to create and manage datastores. With the
API, it's also possible to manage disks and other server-side resources.
-The backup client uses this API to access the backed up data. With the command
-line tool ``proxmox-backup-client`` you can create backups and restore data.
-For QEMU_ with `Proxmox Virtual Environment`_ we deliver an integrated client.

A single backup is allowed to contain several archives. For example, when you
-backup a :term:`virtual machine`, each disk is stored as a separate archive
-inside that backup. The VM configuration itself is stored as an extra file.
-This way, it's easy to access and restore only important parts of the backup,
-without the need to scan the whole backup.

Main Features
-------------
-:Support for Proxmox VE: The `Proxmox Virtual Environment`_ is fully
- supported and you can easily backup :term:`virtual machine`\ s and
- :term:`container`\ s.

:Performance: The whole software stack is written in :term:`Rust`,
in order to provide high speed and memory efficiency.
:Incremental backups: Changes between backups are typically low. Reading and
sending only the delta reduces the storage and network impact of backups.
-:Data Integrity: The built-in `SHA-256`_ checksum algorithm ensures accuracy and
- consistency in your backups.

:Compression: The ultra-fast Zstandard_ compression is able to compress
modern hardware. In addition to client-side encryption, all data is
transferred via a secure TLS connection.
