Proxmox Backup Server (short PBS) is an open-source, enterprise backup solution supporting virtual machines, containers, and physical hosts.[3] The server is a bare-metal solution based on the Debian GNU/Linux distribution, with some extended features, such as out-of-the-box ZFS support and Linux kernel 5.4 LTS.[4] Proxmox Backup Server is licensed under the GNU Affero General Public License, version 3.[5]

Technology

Proxmox Backup Server is written mostly in Rust (programming language)[6] and implements data deduplication to reduce the storage space needed.[7] Data is split into chunks.[8]

History

Development of Proxmox Backup originally began in October 2018 with the need to provide a more efficient backup solution for the virtualization platform Proxmox Virtual Environment than the integrated vzdump backup tool which only allows full backups. The idea was to produce a quicker and more space-efficient solution. In July 2020, the first public beta was announced. Following this, its first stable release was announced in November, 2020.[9]

Operation

Proxmox Backup uses a client-server model and includes features that are targeted towards security and efficiency. It supports incremental backups, data deduplication, Zstandard compression and authenticated encryption (AE).[3] The backup server storing the backup data provides an API to create and manage datastores. A client tool allows to create and manage backups from all the hosts.[2]

For the Proxmox VE platform, the Proxmox Backup client is tightly integrated; the backup storage is configurable as a storage backend on a Proxmox VE node and supports deduplicated backups of QEMU virtual machines and containers.[10] The platform also leverages QEMU dirty-bitmaps, which allows for fast backups from the Proxmox VE client to the server, as only the changed data is transmitted. [11]

Backups can be stored on-premise or synchronized to remote locations with Remotes,[12] and multiple, unrelated hosts can use the same backup server. All client-server traffic is transferred over TLS-1.3 to protect against eavesdropping. To further protect backup data at rest, optional encryption of all backed-up-data is available using AES-256 in Galois/Counter Mode.[13] As the backup server can not access the backup data without the matching encryption keys, it can even be an untrusted host. Administration is done with the command-line tool or with the integrated web-based management interface. Proxmox Backup Server also provides a REST API for third party tools.
