# URZ: Central Data Storage - Backup / Archiving

This source documents the provision of central backup and archiving storage by the Universitätsrechenzentrum (URZ) at Universität Greifswald.

## Key Provisions
- **Infrastructure:** The URZ provides a site-redundant storage area specifically for data backups.
- **Mandated Tooling:** The use of the open-source software **RESTIC** is required for performing data backups.

## Shared Responsibility Model
The service operates on a clear division of responsibilities between the user and the URZ:

### User Responsibilities
- **Data Selection:** Determining which data should be included in the backup and which should be excluded.
- **Scheduling:** Managing the timing and frequency of backup operations.
- **Monitoring:** Overseeing the status of backups to ensure they are completing successfully.
- **Encryption Management:** Setting and maintaining the encryption password. 
    - **Critical Warning:** If the password is lost, data recovery is impossible. The user is solely responsible for the availability of this password.

### URZ Responsibilities
- **Provisioning:** Providing the backup/archive storage space.
- **Availability:** Ensuring that the storage infrastructure remains available.

## Support
Technical issues are handled via:
- The **Groupware** ticket system.
- The URZ hotline (extension 1420).
