Store and Share Data

CSC provides multiple options for storing data while you work on it as well as later in the data lifecycle. There are many factors to consider when choosing a suitable storage solution for your needs.

If you are dealing with sensitive data, explore your options on the sensitive data page.

Storing data during a research project

Allas object storage

A high-capacity storage service for utilising data in computing environments. In Allas, data is stored as static objects. Allas can be used with S3 or Swift API compatible tools. Automatic data backups are not provided.

Pukki is a Database as a Service (DBaaS), suitable for most database use cases. With Pukki you can easily and effortlessly set up a database with a few clicks and manage it as a self-service, instead of manually setting up and maintaining your own database environment.

Storing data while computing

Storage in cloud environments

The cloud environments of Pouta services provide storage space that can be linked to the virtual machines running there. This allows you to build your own data servers and analysis environments, which can be made accessible online.

If you you wish to compare the options above, see the storage comparison table in CSC Docs.

Storing data after a research project

In order to store and reuse data after a research project, it must be well-documented and placed in a repository that enables reuse. We recommend opening research data in a discipline-specific repository or in a general-use service, such as Fairdata or EUDAT B2SHARE. If you can't give access to the data itself, you can often make the metadata of the dataset open.

Only properly described datasets can be stored with CSC after a research project. There may be more conditions for storing data. For example, Fairdata IDA requires you to describe the stored data and to keep the associated CSC project active, even after you publish the data.

Preserving data

Datasets that have long-term value for organisations or on the national level can be preserved digitally. Digital preservation offers reliable preservation of digital information for several decades or even centuries.
