# URZ Server Virtualization Services

This source documents the server virtualization infrastructure provided by the Universitätsrechenzentrum (URZ) at Universität Greifswald. It outlines the technical platform, access requirements, available features, and security measures for users operating root servers.

## Key Provisions
- **Platform**: The system is based on **Proxmox Virtual Environment**, allowing users to fully operate and administer their own root servers.
- **Access**: Access to the primary and secondary virtualization clusters is restricted to the university's internal network or via VPN.
- **Management**: All functions are accessible via an HTML5 WebGUI.

## Technical Features
- **Storage**: Disk images are stored on a **Ceph-Cluster** utilizing **Thin Provisioning**.
- **Data Protection**:
    - **Snapshots**: Available but automatically deleted after 7 days.
    - **Backups**: Daily full backups of virtual machines are performed and retained for 7 days.
    - **Recovery**: Users do not have direct access to full backups; restoration must be requested through the URZ.

## Security
- **Authentication**: Access to the WebGUI is secured using **2-Factor Authentication (2FA)**, integrated with the **UMS** (Account Management) second factor.

## Support
Support is provided via the URZ hotline (ext. 1420) or the **Groupware** ticket system.
