An IT outage means downtime, costs, and can even lead to a loss of trust among customers and partners. Without a reliable backup strategy, the consequences can be even more severe.
With the PBS Storage plans, you can back up your production server environments in a professional backup infrastructure — GDPR-compliant, high-performance, and externally hosted in a German data center. In the event of an emergency, your virtual machines and data can be restored quickly.
With PBS Storage, we offer you a secure and high-performance backup solution for your virtualized IT infrastructures based on Proxmox VE.
Use PBS Storage as an external backup target for your Proxmox VE environment or as an offsite backup in line with the 3-2-1 strategy.
You can choose from several PBS Storage plans with up to 5.000 GB. If you find during use that you need more or less storage space, you can easily switch plans and scale your storage capacity up or down as required.

For larger environments starting at 10 TB or if you require exclusive usage, we recommend our dedicated Proxmox Backup Server plans.
We are happy to address your individual questions and work with you to find the right backup solution.
PBS Storage is ideally suited for:
A minimum contract term of just one month, along with available discount options, ensures flexible and predictable conditions.
You back up directly to a Proxmox Backup Server – with incremental backups, efficient block-level deduplication, and compression. This saves storage space, reduces backup times, and lowers ongoing costs.
Your backup data is stored in TÜV-certified and ISO 27001/27002-compliant data centers in Germany – fully GDPR-compliant and with full data sovereignty.
By physically separating your production environment from your backup storage, you significantly increase your resilience – ideal protection against ransomware and hardware failures.
Our hosting experts provide reliable assistance with all questions related to your backup infrastructure – even outside regular business hours.
Our backup infrastructure runs entirely on 100% renewable energy, enabling secure data protection while supporting sustainable and environmentally responsible IT operations.
Immutable backups protect your data from tampering and deletion. This ensures your data remains reliably recoverable, even in the event of a ransomware attack.
FFor particularly extensive data structures or capacities starting at 10 TB, we recommend a dedicated Proxmox Backup Server.
