Editor's Notes
- B2DROP is a secure and trusted data exchange service for researchers and scientists to keep their research data synchronized and up-to-date. You can store and share up to 20 GB of data for free. The basic functionality of B2DROP is explained in this presentation.
- B2DROP is the EUDAT tool to use when you want to share informal data and documents with your colleagues. It is not recommended for digital artefacts that are finalised and ready for publication and it does not issue Persistent Identifiers which you would ideally need if you were sharing finalised objects. B2DROP offers fine-grained controls to share and to stop sharing the data with your intended collaborators and it also includes a suite of tools that allow versioning of data and offline synchronisation across Windows, Mac and Linux devices. Every EUDAT user has a free allocation of 20 GB of storage. The data are stored in Europe, in a trusted repository at Juelich; I will talk more about security later. The data are backed up offline on a daily basis for disaster recovery. B2DROP is based on the mature ownCloud technology.
- B2DROP is popular with EUDAT users. In December 2016 we had 900 registered users, who have uploaded 700,000 files, taking up around 900GB. We get about 4 requests per second, in daily cycles as you see here. This graph tells us two things: that the service is being used; and that the service is being monitored, which is very important.
- In this talk I will first introduce what you are allowed and what you are not allowed to upload to B2DROP and I will then discuss how you can access the service and what we do with your personal and uploaded data. B2DROP has a web interface and a desktop client, which I will cover, and I will take the opportunity to discuss versioning in a bit more detail. In case you have questions after this session, we have User Documentation for you and the B2DROP will be happy to answer your questions. I will provide pointers to these two at the end of this talk.
- So, what data are allowed, or even encouraged, on B2DROP? You can store any kind of temporary research data, as they come from your original sources or processed, or both. You can upload empirical or theoretical data. The expectation is that you are sharing these data as a basis for collaboration, or publication, but that you are still working on them, or validating them, or they are still in flux; we do not recommend that you reference B2DROP-hosted research data in a publication, as B2DROP will not give you Persistent Identifiers. B2SHARE is the correct EUDAT service for this, or B2SAFE, and there is nothing to stop you from uploading finalised data from B2DROP to any of these two services when you are ready to publish them. B2DROP welcomes any file format, including papers in Word or TeX format, spreadsheets, movies and audio files. As an example, this presentations, and all our training material, has been iterated over B2DROP. The simple rule of thumb is that you can upload any kind of data that has emanated or will be used for you to deliver science.
- So, B2DROP is for researchers and communities to share and store research data. There are few terms and conditions of which you should be aware before using B2DROP. It is probably implied in what I said before, but you are not allowed to use B2DROP for personal, recreational, political or commercial use. Similarly, we expect that no unlawful or inappropriate content will find its way to B2DROP, and the best way to ensure this is for us, the B2DROP users, to not upload such content to the service. The terms and conditions which you will need to accept so as to get access to B2DROP discuss potential sanctions, which include account suspension, termination, deletion of content or criminal proceedings. I am not aware of such instances and I am sure they won’t be needed in the lifetime of EUDAT. I should also say that, while EUDAT offers the service with the expectation that is useful and used by its users, We provide no guaranteed availability at any specific instant. The service has historically been reliable, but the SLA does not support claims against the service hosts if you are late in submitting a deliverable or paper. You can and must read the complete text on the B2DROP website.
- You can access B2DROP via the EUDAT website https://eudat.eu/services-support . Click the small button ‘use’ in the blue B2DROP box.
- Or you can go to B2DROP directly via https://b2drop.eudat.eu/, which is where the EUDAT webpage leads you.
- To use B2DROP you need to register yourself first. This is quite easy. Please fill in your details and use your institutional e-mail address. After confirmation you can use B2DROP immediately!
- In case you would have forgotten your password, you could retrieve it via the Password Self Service. This service is available under the button CLICK HERE, which you use for creating a new account too. Simply follow the steps and you’ll use B2DROP very soon again indeed.
- I think this is a good point to talk about security on B2DROP. The files that you upload are only available to you, until you decide to share them. I will talk about sharing in a minute. In case of emergency, an administrator could access your data, but we hope it will never be necessary. The data are stored at Juelich Supercomputing Centre, they don’t leave Europe. Juelich takes daily back-ups on off-site tape, for disaster recovery. You personal, user data, are also stored at Juelich, but note that it is not encrypted. Your data will be moved to another supplier only if they join B2DROP as hosts, or if they take over from Juelich. We expect such 3rd parties to be EUDAT partners.
- Let’s go back to the B2DROP website. The obvious functionality is to upload a file. Each file can be up to 10 GB. At the top you see the plus sign; click on that and select “Upload”. This pops up your desktop file browser where you can select which file to upload by clicking “Open”. As is expected on modern browser-based tools, you can also drag-and-drop a file. If you try to upload a file with the same filename as a file already on B2DROP, the “File conflict” pop-up will give you information about the namesake artefacts and allow you yo make a decision if you want to upload and supersede as the current version or not.
- This is a good time to discuss versioning. Files uploaded are automatically versioned and it is pretty straightforward to check the previous versions. On the web interface click on the three dots, select “Details” and check out Versions on the right. When you upload a file, it overwrites previous versions, as we saw on the previous slide, with old versions retained. B2DROP uses an algorithm to reduce the number of versions progressively as time goes by; the older a version, the more likely to be removed. B2DROP starts deleting or stops maintaining versions after you exceed 50% of your quota.
- B2DROP lets you group your files in folders. On the Plus-sign menu, click “Folder” and give it a name. You can deposit files in the folder now. B2DROP also lets you create and edit a text file, again from the Plus-sign menu. As soon as you exit the file, it is saved. You can rename files and folders. Select the object to rename, click on the three dots on its row and select the Rename option. You can see “Delete” and “Download” are available there too.
- B2DROP allows you to create contacts; these will come in handy when you start sharing artefacts. Click the arrow-down next to “Files” and select “Contacts”. You can then click on ““+ New contact”. You can import contacts in batch from Variant Call Format file; Click on “Settings” at the bottom, then “Import”. You can also group the contacts you have added. Select a contact and add a Group name, in the “Groups” field; this also creates the group.
- As I said before, B2DROP is all about sharing the objects with your collaborators. Having populated the repository, we can share the data. Click on the down arrow on “Contacts” and select “File”. Select an object to share and click the Share icon. You can use contacts or email addresses and you can share with users of other ownClouds that you are collaborating with. If you tick “Share link” then you can notify these users using your mail client, skype, whatever works for you. You can control if the people you share with can edit the object, you can password-protect the object and you can set B2DROP to expire the sharing at a date of your choice. Or you can stop sharing by unticking “Share link”. This is a very powerful feature of B2DROP.
- As I mentioned before, you can also use B2DROP from a desktop client. The client is developed by ownCloud and the B2DROP webpage can take you to their website to download it. Click on your username on the right and select Personal. On the left “Sync Clients” appears and you can then select the appropriate app, in this case desktop, but you can see that if you have an Android or Apple phone you can use these clients too. We won’t cover these today, but if you click on “Desktop app” you are redirected to the ownCloud website and can select the relevant operating system for you. You can then follow the instructions and, when the program starts, you use the B2DROP address on https://b2drop.eudat.eu/ and log in with your B2DROP-registered email and your password. The client is very useful when on the go, as, if you have it running, it will synchronise files when you reconnect.
- Another method we have found useful is to mount the folder on your desktop, using the WebDAV protocol, which then allows the B2DROP folder to appear in your file browser. Again, similarly to using the client, saving a file will synchronise with B2DROP, but note that this only work when connected to the network. This method is supported for Macs, Linux and Windows computers, and I will describe these now.
- EUDAT runs a specific help desk system to support B2DROP users and it can be accessed via http://www.eudat.eu/support-request
