How does Proxmox Backup Server work?

Proxmox Backup Server (PBS) works as a standalone backup server for virtualized environments. It is designed to easily backup and restore data that is stored on virtual machines and containers. <
Proxmox Backup Server allows you to back up data from a variety of sources, including physical servers, virtual machines, containers, databases, and other applications. Backup data is stored on a disk array or on external storage. <
Proxmox Backup Server uses incremental backup, which means that only changes to the data are backed up and stored on the server. This process minimizes storage requirements and reduces the time required to perform backups. This makes backups faster and allows you to maintain backups for longer periods of time.
PBS also allows users to set up backup scheduling so that backups are performed automatically at a specified time interval.
When restoring data, you can simply select the files or entire virtual machines you need and restore them to the original or new server.

Installation

What will you need?

To run Proxmox Backup Server, you will need a server on which to install this backup solution. You can use a physical server or a virtual server. For this to make sense it is essential that if it is a VPS it must run on a different physical server. And it should also be located in a different location, because the idea is to not only back up, but to back up to another device that is located somewhere else. This gives the backups distance from software problems, hardware problems, or even natural events that0 are at the location where Proxmox is running.

Manual installation

You can install PBS on an already prepared server with a Linux distribution Debian by adding the Proxmox Backup Server repositories and then installing this backup solution via the package system command. Into the file /etc/apt/sources.list Add:

deb http://download.proxmox.com/debian/pbs bullseye pbs-no-subscription
The following commands will update the repositories and install Proxmox Backup Server:
apt update
apt install proxmox-backup

Installing from CD

Or download the installation ISO to boot the installation wizard, which will guide you through the installation of the operating system, including the Proxmox Backup Server backup solution. The installation wizard is intuitive and you end up with a working Proxmox Backup Server. For less knowledgeable server administrators, I would recommend this server. Otherwise, the choice of method will depend on the specific situation.

Once installed, a web-based administration interface is available via the encrypted HTTPS protocol. This interface runs on port 8007. It is available on the IP or domain of your newly installed Proxmox Backup Server, for example https://10.0.0.12:8007/

After installation

If you are not using commercial support, you will need to edit the repositories where the Proxmox Baxkup Server updates are. The repository configuration is here: /etc/apt/sources.list.d/pbs-enterprise.list To use the public repository, replace the current configuration with this line:

deb http://download.proxmox.com/debian/pbs bullseye pbs-no-subscription

Use

  1. On PBS, you need to create a datastore where backups will be stored. This can be a local directory, a local disk, or network storage.
  2. It is advisable to create a new user with limited rights who will have rights to the datastore.
  3. In your Proxmox mounted datastore of type Proxmox Backup Server-
  4. You can then see this new datastore available in your Proxmox and can set up backups to it.
  5. In PBS you will then see the individual backups you have created.
  6. Set the rules in PBS for how backups are to be deleted. You can set to keep the last few backups, one weekly one monthly etc
