Service Description

What is bwSync&Share and who can use the service?

The bwSync&Share service is an online storage service for employees and students of universities and colleges in Baden-Württemberg. It has been operated at the Karlsruhe Institute of Technology (KIT) since January 1,2014. Information about the regional service can be found on the ALWR website: http://www.alwr-bw.de/kooperationen/bwsync-share-in-der-dfn-cloud/.

The service is also offered to the members of the DFN Association within the service of the DFN Cloud. (https://www.dfn.de/dfn-cloud/).

The service is not suitable for storing personal data.

Support is provided by the local helpdesk of the respective home organisation.


Synchronize data

bwSync&Share enables users to synchronize or exchange their data between different computers and mobile devices. In addition to the hardware-independent web interface, different clients are available (Windows and Mac desktop, apps for Android and iPhone/iPad).

Share data

bwSync&Share offers the possibility to access data jointly and to exchange it with other users or to edit it together. By inviting to a folder, a personal storage quota is made available to the invited party in accordance with the granted authorization.

You can also send links to download files or folders.

Who can use the service?


Users ofthe participating colleges and universities are referred to in this manual as Shibboleth users. A Shibboleth identity provider is responsible for the transmission of the necessary data for login and authorization queries between local user administration and the bwSync&Share service.

The local user administration determines whether all or only a certain group within a local institution is authorized. If you have any questions, please contact your local service desk/helpdesk.

Shibboleth users must register for the service. The terms and conditions of use of the service must be approved.

External Users

In order to facilitate cooperation with partners outside the participating institutions, Shibboleth users can invite them to the service via the e-mail address. In each case, a separate user account is created in bwSync&Share, which is not assigned to a local institution, here called external users. The initial data are the e-mail address to which the invitation is sent and the password set during registration. External users must also register and agree to the terms of use.

External users do not receive their own storage space and are not allowed to perform any administrative actions without explicit authorization (by a Shibboleth user). The locked actions are correspondingly greyed out or are not displayed.
