Proxmox Backup Server is an enterprise backup solution that can be used to backup and restore virtual machines, containers, and physical hosts. Supporting incremental and completely deduplicated backups greatly reduces network load and saves valuable storage space. Powerful encryption and methods to ensure data integrity enable you to confidently back up data, even to an untrustworthy target location.

In modern data centers, the main focus is on minimizing downtime and protecting data security. Therefore, reliable backup software is one of the most important infrastructure components that you can invest in. The easy-to-use Proxmox Backup Server can increase productivity, allowing you to backup data in a space saving manner, quickly recover, and effectively reduce work time through a simplified web-based user interface.

Functional characteristics

Backup is one of the most important infrastructure components that you can invest in. The need to minimize downtime and quickly recover from data loss or ransomware attacks is a core aspect of IT management.

Open source platform for backup and recovery

Data loss or damage may occur at any time due to deletion, ransomware, or other dangerous reasons. Therefore, regular backup of important data is crucial. To improve productivity and achieve operational goals, a user-friendly Proxmox backup solution allows you to backup data in a space saving manner, quickly recover during recovery, and effectively reduce work time by simplifying management.

Open Source

Proxmox backup is an independent solution. The open source nature of the Proxmox software stack means that you can trust a secure and flexible product. The source code is free and open source, licensed under the GNU Affero General Public License v3 (GNU AGPL, v3). Therefore, you are free to use the software, check the source code at any time, or contribute to the project yourself.

Incremental and de duplication

The backup is sent incrementally from the client to the Proxmox backup server, and the data is then deduplicated. Usually, there are few changes between periodic backups. Only reading and sending changes can reduce storage space usage and network impact.

Periodic backups typically generate a large amount of duplicate data. The deduplication layer in Proxmox backup solution reduces the amount of duplicate data and reduces the physical space required for data storage.

When performing deduplication, there are different strategies that can achieve optimal performance and/or deduplication rate. According to the data type, data can be divided into fixed or variable sized blocks. The Proxmox backup server supports both strategies.

performance

The entire Proxmox backup software stack is written using the modern, fast, and memory efficient programming language Rust. Rust provides high speed and memory efficiency, partly due to its lack of runtime and garbage collector. Its rich type system and ownership model ensure memory security and thread safety.

compress

Proxmox uses ultra fast ZStandard (ZSTD) compression, which can compress several gigabytes of data per second. ZSTD is famous for its high compression ratio and very fast compression speed.
