Research Data Management: Data Storage and Security
|A data storage strategy is important because digital storage media are inherently unreliable, unless they are stored appropriately, and all file formats and physical storage media will ultimately become obsolete|
Data storage arrangements will also need to reflect the sensitivity of your data; you may have data that are covered by privacy laws or confidentiality agreements and for these you will need to consider how data security will be guaranteed e.g. use of data encryption, passwords, etc.
The UK Data Archive also provides good guidance on how to store sensitive or confidential data
You will also need to consider how your data will be shared during the project.
Avoid single points of failure
A single point of failure occurs when it would only take one event to destroy all data on a device. Imagine if that happened right now. Do you have a backup of your data to restore from? Is it current? Who is responsible for ensuring appropriate storage and regular backups?
Good practices for avoiding single points of error:
Replicate your data to a reliable backup system
Use a README.txt file to create an inventory of the locations of your important data. This might include descriptions of users, computers, server addresses, backup locations and third-party storage details.
Organise a back-up system
To reduce risk as far as possible, backups should be made after every change to data or at regular intervals. You can use an automated backup process to back up frequently used and critical data files.
