When choosing a storage for the research data, you have to consider several things:
If you can answer these questions, it helps to determine what kind of storage system you need. Storage services provided by Tampere higher education community can be modified according to need.

Choose file formats according to long-term access if possible and use formats which are in common use by the research community. Favor following properties:
You may have to choose certain formats during data collection and analyses, and others for long term preservation. The formats you choose can depend on how you plan to analyse your data or software compatibility. You may need to convert your data files to a preservation file format at some point of your research.
Some preferred file formats for long term preservation:
With backups we refer to the creation of additional copies of your data that can be used to restore data if the original is damaged or deleted. You should always have at least 3 copies of your data, and copies should be geographically distributed.
Many data storage systems have automatic backup functions and even some version management tools are included. It's recommended to choose your data storage according to that if possible. Do not count backup functions as a part of version management though, you should always have other copies of your data despite of backups.
The idea of version control is to make copies of files while processing them further and to be able to go back and retrieve earlier version of any file if needed. It is important to ensure that different copies in all different locations are subject to version control. You can manage your version control many ways. A simple version control can just be based on saving multiple versions of your files and naming them descriptively enough. This method might not be enough if collaborating with multiple people though, it would be better to establish some ground rules for version control.
Some storage services offer version control features like snapshots and backup versioning, some services automatically create new versions of your files every time you modify them and some services offer version branching and merging. These are technical tools for version control to enhance working or to help users in situations when their own version control fails. Version control tools like snapshots or any backup related tools should not be regarded as a part of your version management as backups are for recovering from the worst case scenarios when your own version control fails.
Data security means protecting data from external and internal hazards, like accidents and errors but also from unauthorized access or use. Data security has to settle to a level with the nature of the data and risks involved. Data that contains confidential or personal information should be treated with higher levels of security.
It's advised to make a data security plan as a part of your DMP. It can contain following aspects:
