An Introduction to Proxmox Backup Server (PBS)

With the increasing need for reliable backup solutions in today’s digital landscape, Proxmox Backup Server has emerged as a comprehensive solution for businesses and individual users alike. But what exactly is Proxmox Backup Server? In this blog, we’re going to, at a high level, cover the details. In a later blog post, we’ll go into more details such as connecting a Proxmox VE server, backing up, and restoring not only the entire VM but individual files as well.

What is Proxmox Backup Server?

Proxmox Backup Server (PBS) is an open-source, enterprise-level backup solution designed to backup and restore virtual machines, containers, and physical hosts. Developed by the creators of Proxmox Virtual Environment (PVE), PBS integrates seamlessly with PVE but can also function as a standalone backup server for any other environment.

Beside the computer, there's a stack of hard drives connected by colorful cables. Above the scene, a cloud symbol glows softly, indicating cloud backup, and small data packets move from the computer to the cloud.

Key Features

  1. Incremental Backups: PBS uses a deduplication-first approach, which means that after the initial full backup, only the changes (or increments) are stored. This results in faster backup times and reduced storage requirements.
  2. Data Integrity: Using advanced checksumming techniques, PBS ensures that your data remains intact and corruption-free throughout its lifecycle.
  3. Encryption: Security is a prime concern, and PBS offers end-to-end encryption, ensuring your data is secure both at rest and during transfer.
  4. Compression: Reduce storage needs with built-in compression features.
  5. Web-based User Interface: Manage your backups with an intuitive GUI, making it easier to schedule, monitor, and restore backups.
  6. Integrated with Proxmox VE: For those using Proxmox VE, PBS provides a unified experience, allowing for seamless backups of VMs and containers.
  7. File-level Restore: In addition to restoring entire VMs or containers, PBS allows for granular, file-level restores.
  8. Remote Synchronization: Sync your backup data to remote locations, ensuring redundancy and data availability even in case of a primary site failure.
