# Federated Data Storage

Federated Data Storage refers to the architectural nature of the [[matrix]] protocol where communication data is not stored in a single central location but is replicated across the servers of all participants in a conversation.

In the context of the [[universitat-greifswald]]'s Matrix service:
- Data is stored on the university's home server.
- Data is also stored on the external servers of any communication partners.
- The university has no administrative control over external servers and cannot guarantee the deletion of data once it has been federated to an external party.
