These guidelines describe subject-specific aspects of operation and specifications that must be observed when using the service. They supplement the usage guidelines for information processing systems of the LRZ (PDF), as well as the respective usage guidelines of the university or organization to which the user belongs.
Scope of application and authorized users and institutions
Diese Richtlinien gelten für alle Nutzer des Dienstes sowie die vom LRZ dafür bereitgehaltene IT-Infrastruktur. Nutzungsberechtigt sind Mitarbeiter und Studierende der Technischen Universität München, der Ludwig-Maximilians-Universität München und der Bayerischen Akademie der Wissenschaften, sowie weitere registrierte bayerische Hochschulen und Institutionen gemäß LRZ Dienstleistungskatalog.
Readability of the data
As cloud storage, the LRZ operates highly available, largely scalable, high-performance storage systems in access-secured, fully air-conditioned data center rooms (private cloud). This also includes adequate climatic conditions and building protection.
There is no one hundred percent guarantee for the unlimited readability of the data on the storage systems. Neither the manufacturer of the storage systems or the software used nor the LRZ as a service provider can be held liable in the event of an error. The aforementioned security measures create a reliable framework. Nevertheless, they are not a guaranteed protection against, for example, operating errors. The correct application and configuration of the service is the responsibility of the user.
Responsibility for file contents
The user of the service is solely responsible for the legal and constitutional conformity of the contents of the stored data. The user undertakes not to store sensitive data (e.g. personal data) unencrypted and not to make it accessible to unauthorized third parties.
By default, all data is stored unencrypted at the Leibniz Computing Center. The customer is responsible for ensuring that the data can be interpreted.
In the storage areas provided for this purpose, it is possible to share or exchange data with other users by assigning appropriate access rights. The release of data is the responsibility of the user (observance of copyright). As the owner of a data area (personal data storage) and user of a shared data area (project storage), it is recommended to check the contents regularly. This also applies with regard to the risk of distributing malware or malware-infected files. It is recommended to perform a decentralized virus scan on the local device using suitable antivirus software. It is expressly pointed out that a central virus check does not take place at the LRZ.
The LRZ assumes no responsibility for any misuse.
Data security and encryption
The data is stored exclusively on LRZ-owned devices in the data rooms of the data center without encryption. The LRZ takes appropriate precautions to ensure that the security and integrity of the data is maintained. Furthermore, the LRZ uses the means at its disposal to ensure that no unauthorized external access is possible to the data stored in the storage system.
The data is only passed on to third parties if legal obligations must be met.
Data protection according to DSGVO
Availability, maintenance times
The LRZ makes every effort to ensure the highest possible availability. For this reason, the most important components of the system are configured redundantly. An annual availability of the systems of at least 99% is aimed for. Work on troubleshooting is only guaranteed on weekdays during normal business hours. Maintenance agreements have been concluded with the manufacturers for all hardware and software components. The agreed SLAs generally only cover normal business hours on working days with an on-site response within the next working day. Service interruptions necessitated by planned maintenance work on hardware and software are announced several days in advance in the current LRZ information. In exceptional cases (emergency maintenance), an immediate service interruption can also be announced.
As a rule, the following times apply to the announcement:
Interruption shorter than 1 hour: 5 working days
Interruption longer than 1 hour: 15 working days
Retention period, deletion of data
The use of the service or the provision of the data is always linked to the user's registered account in the MWN directory of the LRZ. If this ID is deactivated or deleted (e.g., when a person leaves the institution authorized to use the service), the associated files are automatically and irretrievably removed from the storage system. This may result in system-related delays in deleting the data. If the user still requires the data after deletion of the identifier, he/she is responsible for transferring the data from the cloud storage system in good time.
No files of a user with a deactivated ID that are located within a storage area shared by several users (project storage) will be deleted.
If desired, a user can request deactivation or deletion of his/her account via the service desk of his/her institution or via the LRZ service desk.
The LRZ reserves the right to block the use of the service and thus access to the stored data in individual cases. The service will be blocked, for example, if the user violates applicable law or the guidelines stated here.
Should individual provisions of this Policy be invalid or unenforceable, or become invalid or unenforceable after entry into force, this shall not affect the validity of the provisions of this policy in other respects.
The LRZ reserves the right to change these guidelines. Changes may become necessary due to mandatory legal requirements, among other things. It is recommended that you re-read the current usage guidelines from time to time. This policy is effective immediately and supersedes all previous policies.
