The document discusses use of the B2DROP service by researchers.
Modified: 19 June 2018
B2DROP is a secure and trusted data exchange service for researchers and scientists to keep their research data synchronized and up-to-date and to exchange them with other researchers. In this document the user can find instructions on how to connect B2DROP to their computer using the MacOS, Linux and Windows operating systems.
B2DROP is an easy-to-use, user-friendly and trustworthy storage environment which allows users to synchronise their active data across different desktops and to easily share this data with peers. The service is directed towards all European researchers whose institute does not host such storage. B2DROP is based on NextCloud. The service is intended for the long-tail and still volatile data which can change and are still subject to active research e.g. drafts of research papers. Therefore, B2DROP offers versioning of all ingested files but does not attach persistent identifiers to them.
B2DROP is hosted at the Jülich Supercomputing Centre, which guarantees that your research data stay in Europe. Daily backups of all files in B2DROP are taken and kept on tape. Data are encrypted on transmission through the exclusive use of the https protocol for data transfer. Each B2DROP user is allowed 20GB of storage.
B2DROP offers an intuitive user-interface via the web; this is mostly self-explanatory, with highlights discussed below. In addition to web access, users can mount B2DROP as a drive on their desktop machines via WebDAV, or use a desktop client which also allows offline synchronisation. In this section we give some quick-start instructions for the MacOS, Linux and Windows operating systems. For further help please consult the NextCloud documentation. Please note that a PDF copy of the ownCloud user manual is also available in your B2DROP home directory.
Web usage highlights
B2DROP includes customisations over ownCloud, highlighted below. Some finer points are also discussed.
Please visit https://b2drop.eudat.eu/ and seek "Not registered yet? CLICK HERE" under the "Log in" button. Click on it and follow the simple instructions.
Sharing a file
There are two ways to share a file: via ownCloud functionality, you can share files with users in the B2DROP directory and on other ownClouds; and with anyone on email by sharing a link. Hover over an entry and click on the "Share" symbol, as shown on Figure 1.
Figure 1. The B2DROP "Share" icon.
Share via ownCloud: If you start typing on the box shown on Figure 2, options from the B2DROP directory become available. Or you can use the format firstname.lastname@example.org/owncloud for users on other ownClouds. You need to repeat for each person you want to allow access.
Figure 2. The B2DROP menu to share with NextCloud users.
Share publicly: If you click on "Share link" instead, a URL is made available to you as shown on Figure 3. You can distribute this using your preferred means.
Figure 3. The B2DROP menu to share publicly.
Figure 4 shows the different icons that shared folders get: the chain represents a publicly shared link; the triangle signifies a locally shared folder.
Figure 4. The B2DROP shared folder icons (publicly and locally respectively).
More information on sharing is available from the ownCloud user documentation.
Accessing shared artefacts
When a B2DROP local user shares a file or folder with you, then a link to this artefact is added to your B2DROP home folder.
However, when accessing an artefact that was shared with you as a link, then the "Add to your ownCloud" button appears at the top right of the B2DROP webpage; see Figure 5. Clicking on it adds to your B2DROP home folder a link to this page.
Figure 5. The B2DROP "Add to your ownCloud" button.
Hover over a file that you won and note the three-dot symbol shown on Figure 6. If you click on that, you are presented with options to see the details of the file, rename it, download it onto storage available from your client or delete it from B2DROP.
Figure 6. Other file options on B2DROP.
Mount B2DROP using the WebDAV client
You can use the WebDAV client to mount your B2DROP folder as a drive on your computer. Note that this mode of using B2DROP requires you to be connected to the internet in order to open and save files, while the desktop synchronization client discussed below allows you to also manipulate files while offline and synchronize when re-connected. Instructions for using the WebDAV client for MacOS, Linux and Windows are discussed below.
You can mount B2DROP in your "Finder" by clicking on "Go" on the drop-down menu and then "Connect to server" and entering: https://b2drop.eudat.eu/remote.php/webdav/
You then need to login with your username (email address) and password.
You can also mount B2DROP with Cyberduck by providing the above-mentioned information to the client.
The instructions below have been tested on Ubuntu but they should work for every Linux distribution supporting the NAUTILUS or GNOME file system.
You can mount B2DROP with NAUTILUS. Then select "Go to File --> Connect to server" Type in: davs://b2drop.eudat.eu/remote.php/webdav/. You then need to login with your username (email address) and password. Mounting via davfs is also possible, but it requires sudo access.
sudo apt-get install davfs2
sudo mount.davfs https://b2drop.eudat.eu/remote.php/webdav/ oc
You then need to login with your username (email address) and password. You can unmount with the following command: sudo umount.davfs oc
You can map B2ROP as network drive by entering the following URL as a folder: https://b2drop.eudat.eu/remote.php/webdav/
You then need to login with your username (e-mail address) and password.
Note: you may need to set your computer to allow Basic Authentication; please follow the Microsoft instructions for this. Because B2DROP is available under https, Option "1 - Basic authentication enabled for Secure Sockets Layer (SSL) shares only" should suffice for Windows Vista and later.
You can also synchronize B2DROP with your computer using ownCloud desktop clients. Just download the latest version of the ownCloud Desktop Synchronization Client from the ownCloud Website. There are clients for multiple Linux distributions, Mac OS X, and Microsoft Windows, as discussed below. For more information on the client, check out the documentation.
- Mac OS X and Windows
Installation on Mac OS X and Windows is the same as for any software application: download the program, double-click it to launch the installation, and then follow the installation wizard. The installation wizard takes you step-by-step through configuration options and account setup. You need to enter the URL of the B2DROP ownCloud server, which is https://b2drop.eudat.eu/. Then enter your username (email address) and password.
- Linux Distributions
Linux users must follow the instructions on the download page to add the appropriate repository for their Linux distribution, install the signing key, and then use their package managers to install the desktop sync client. For the configuration options and account setup you need to enter the URL of the B2DROP ownCloud server which is https://b2drop.eudat.eu/. Then enter your username (email address) and password.
A note on B2DROP versioning
B2DROP supports file versioning, and it does so automatically. Access to the previous versions is straightforward on the web GUI and the desktop client; the file gets overwritten by the selected version, with other versions (including newer) retained.
However, in order to preserve disk space, B2DROP preserves a subset of the versions, progressively reducing the number of retained versions as time goes by. The scheme is discussed under "Version Control" in the ownCloud manual, but it is important to note that B2DROP will remove older saved versions and/or stop maintaining versions while the user exceeds 50% of their quota.
In future, further B2DROP instances at other EUDAT centres are planned which can be federated to allow data exchange between these instances. In general the developer team is looking into possibilities to allow federations between B2DROP and other OwnCloud instances.
EUDAT is open to suggestions for B2DROP plugins and is interested in developing such plugins for communities and hosting community-specific B2DROP instances.
Support for B2DROP is available via the EUDAT ticketing system through the webform.
If you have comments on this page, please submit them though the EUDAT ticketing system.

Service breaks advertised in short time (less than 7 calendar days before the maintenance) are considered as emergency service breaks. Unplanned service break due to emergency maintenance is only done as a part of critical incident management process. Unplanned service breaks are taken into account on Service Reliability.
During maintenance windows, Service Availability and/or service response will be reduced.
The services covered by the scope of this SLA are provided with the following level of support.
Service Desk Response Time
Service Desk Resolution time
Service Desk Response Time is the Target time for a Service Desk to respond to a service request. Service Desk Resolution time describes the maximum time for a Service Desk to fulfil the standard service request. In most of the cases Service Desk Resolution time is considerably shorter than the Service Desk Resolution time given above. Non-standard service requests include service requests of new customers and capacity requirements over 50 TB.
4.1. Incident handling
Disruptions to the agreed service operation will be handled according to an appropriate severity classification of the incident. In this context, following guidelines apply:
Incident Responce Time
Total loss of a Service:
4 hours during normal working time
Service is degraded:
1 working day
Minor incident / warning:
4 working days
Security incident resolution coordination is to be lead by CSC security officer. Security incident is defined such that there has been an event indicating possible unauthorized access to data, applications, services, networks and/or devices by bypassing their underlying security mechanisms. Alternatively, known vulnerability and tools to utilize the vulnerability exist.
CSC helpdesk agents acknowledge the reception of the information about the incident, notify the severity level and provide, if possible, a first and not committed estimate of the time required to restore normal operational status. If an incident cannot be solved within the mentioned timeframe, i.e. Incident Resolution time, a statement explaining the reasons is issued. This statement will contain a plan how the incident will be solved during the following working days.
5. Service level targets
The following are the agreed service level minimums for the B2DROP Service:
Service Level target
