Data

CSC provides services and instructions for managing research data throughout the data lifecycle: planning data management, finding datasets, storing data, moving data between services, and publishing data.

CSC also provides support for sensitive data workflows. See the sensitive data section in the docs.

This section helps you choose the right instructions for your data-related task.

Working with data

Start here if you are planning how to manage, document, store, find or publish research data.

Moving data

Use these instructions when you need to transfer data between your local workstation, CSC supercomputers, Allas, IDA or other CSC services.

Allas object storage

Allas is CSC's object storage service for storing and sharing research data. Use the Allas instructions when you need persistent object storage, or need to host and share datasets between projects, or between multiple CSC platforms (e.g. cPouta and Roihu).
