Proxmox Backup Server
Proxmox Backup Server (PBS) is a specialized open-source solution for the backup and restoration of virtual machines, containers, and physical hosts. It was developed to manage backups efficiently, minimize storage requirements, and keep recovery time objectives (RTO) as short as possible.
A central feature of the Proxmox Backup Server is block-level deduplication. Since modern IT environments often contain many similar data sets (e.g., identical operating system files across different virtual machines), PBS recognizes these redundancies. Instead of saving a complete new backup every time, only the modified data blocks are transmitted and stored. This not only reduces network load but also significantly saves storage space on the backup infrastructure.
For businesses, the security of backup data is of paramount importance. PBS supports end-to-end encryption directly on the client side. This means that data is encrypted before it leaves the source server, making it unreadable to unauthorized parties both during transport and on the backup server itself. Additionally, the technology protects against data loss through checksums, which continuously verify the integrity of the backups.
From a compliance and data security perspective, the use of Proxmox Backup Server at exaSys is particularly relevant:
- Data Sovereignty: By operating within our Swiss data centers, customers retain full control over where their backups are located.
- Efficiency: Incremental backups allow for very frequent backup intervals, minimizing potential data loss in an emergency (RPO).
- Granular Recovery: Not only entire systems but also individual files or directories can be restored quickly and easily.
exaSys specifically deploys Proxmox Backup Server where customers require high-performance, transparent, and cost-effective backups for their Proxmox environments. Customers benefit from a solution that provides professional enterprise features without complex licensing models.
Whether Proxmox Backup Server is the optimal solution for your infrastructure is something we evaluate together based on your requirements for backup windows, storage capacity, and disaster recovery scenarios. exaSys supports you in implementing a backup strategy that combines technical efficiency with the highest level of data security.
