Storage Drivers

Storage drivers are responsible for safely transferring a finished archive to a specific storage location.

Work in Progress (WIP)

This section is still under active development. Information and specifications can still be changed in the future.

Tasks and Responsibilities

Writing Data to Storage

Provides an interface to write archives to storage

  • Data must be stored in a way that overriding existing data is not possible, even if archive file names are identical

Reading Data from Storage

Provides an interface to read archives from storage

  • If data retrieval is not possible, the data can not be retrieved via Moodle
  • If data retrieval is not possible, GDPR compliance (automatic deletion, personal data retrieval) is not possible

Authentication

Store credentials for authentication against the storage system, if applicable

  • Credentials must only be visible to the system administrators

Connection Check

Provides a way to check the status of the storage system connection (e.g., connection test, test write, test read)

Storage Space Monitoring

Provides a way to monitor the available storage space, if reported by the respective storage system / interface

Configurability

Allowing independent configuration of the different available storage drivers (e.g., storage path, storage system credentials, ...)
