Proxmox Backup Server is an enterprise-class, client-server backup package which provides strong encryption without compromising on speed or flexibility. The Backup Server is based on a minimal Debian GNU/Linux distribution with built-in ZFS support. Thus, it can be installed on bare-metal, using the downloadable ISO image.

The backup server comes stocked with all the essential management tools you need, as well as an easy-to-use, web-based interface. This allows for simple, out-of-the-box management of your server, either through the command line or a standard web browser.

Proxmox Backup Server is licensed under the GNU AGPLv3 and is open for downloading and using. It is recommended that the server runs on dedicated hardware rather than being run as a virtualized instance.

Download and Install

1.Download ISO image

The ISO image file is an image of a disk. Download the Proxmox Backup Server ISO, then copy it to a USB flash drive or CD/DVD in order to use it.

2.Boot from USB

...then, after booting, press 'Enter' to start the installation wizard on your dedicated hardware.

If you need help with the installation read the documentation or get a subscription for technical support.

3.Configure via GUI

You can do everything via your web browser. You don't need to install a separate management tool.

Note: Proxmox Backup Server is a bare-metal installer, please be aware that the complete server is used and existing data on the selected disks will be removed.

System Requirements

When running Proxmox Backup Server in a production environment, you will need high quality server equipment to ensure that your backed up data is safe.

Recommended Hardware

For a production setup, we recommend dedicated hardware. This is especially important for critical tasks like backups where many hosts/VMs/containers save their critical data.

CPU: Modern AMD or Intel 64-bit based CPU, with at least 4 cores
Memory: minimum 4 GiB for the OS, filesystem cache and Proxmox Backup Server daemons. Add at least another GiB per TiB storage space.
OS storage:

·32 GiB, or more, free storage space

·Use a hardware RAID with battery protected write cache (BBU) or a redundant ZFS setup (ZFS is not compatible with a hardware RAID controller).

Backup storage:

·Prefer fast storage that delivers high IOPS for random IO workloads; use only enterprise SSDs for best results.

·If HDDs are used: Using a metadata cache is highly recommended, for example, add a ZFS special device mirror.

Redundant Multi-GBit/s network interface cards (NICs)

For Evaluation

These minimum requirements are for evaluation purposes only and should not be used in production.

CPU: 64bit (x86-64 or AMD64), 2+ Cores
Memory (RAM): 2 GB RAM
Hard drive: more than 8GB of space.
Network card (NIC)

Supported web browsers for accessing the web interface

To access the web-based user interface of the Proxmox Backup server, you need one of the following browsers:

Firefox, a release from the current year, or the latest Extended Support Release
Chrome, a release from the current year
Microsoft’s currently supported version of Edge
Safari, a release from the current year

Install Proxmox Backup Server on a Debian System

If you want, you can install Proxmox on top of a running Debian 64-bit system. This is especially interesting, if you want to have a custom partition layout.
