FAQ: mantau Cloud Storage
The cloud storage in mantau is a central storage area for files, documents, images and other digital content. It is directly integrated into collaboration within groups and enables shared access to relevant information.
Files are stored and managed in a structured manner within groups, projects or organisational units. Authorised members can access the content, upload, download or share files. This creates a centralised and traceable document repository.
Access to files is controlled via group memberships, roles and permissions. Organisations can specify which individuals are permitted to view, edit or manage files. This ensures that confidential information remains protected and accessible only to authorised users.
Yes. The cloud storage feature in mantau enables files to be stored centrally and shared within an organisation. Unlike when sent by email, documents remain stored in a fixed location and the latest version is available to all authorised members.
Yes. New members are granted access – depending on their permissions – to existing files and documents within their groups. This ensures that information remains available in the long term and does not need to be redistributed or searched for again.
Files are stored within the relevant group structure and remain permanently available. This means that documents can be retrieved even after a long period of time, without having to rely on old emails or chat histories.
Yes. The cloud storage is part of the GDPR-compliant mantau platform. The data is stored in Germany and protected by defined role- and permission-based access controls. This enables organisations to retain control over access to their documents and files.
