The use of cloud storage in digital preservation is a rapidly evolving field. This paper looks at how it is developing, what the options are, and the practices, requirements and standards that archives
should consider. It examines case studies of five UK archives and how they use cloud storage solutions. Digital preservation is a significant issue and there is an increasing demand for
archival storage. The need is not a one time purchase since content will continue to expand. The paper contains:
- General overview of key areas, definitions, and issues;
- A Step by Step Guide of creating a business case and important options;
- Future developments of cloud storage over the next few years;
- Current Good Practices to follow;
- Case studies of UK archives that have implemented cloud solutions with detailed of their organization, requirements and approaches.
- Sources for additional advice and guidance
- A Table of legal issues to be aware of with cloud storage.
There are some advantages to cloud storage:
- potential cost savings from easier procurement and economies of scale, particularly for smaller archives
- automated replication to multiple locations and access to professional managed digital storage
- ability to add other dedicated tools, procedures,workflow and service agreements, tailored for digital preservation requirements
- As digital preservation becomes more of a strategic interest, cloud may be a component of required solutions and enable wider participation and collaboration.
dedicated IT security staff ensuring the safety and security of the data. There are also legal issues which must be understood.
When considering cloud storage, it is important to be aware of three key items:
- data held in archives must be expected to be both preserved and accessible beyond the commercial lifespan of any current technology or service provider;
- an approach to addressing serious risks, such as loss, destruction or corruption of data that is based purely on financial compensation will not be acceptable, as this takes no meaningful account ofthe preservation and custodial role of archives;
- there must be an explicit provision must be made for pre-defined exit strategies (e.g. synchronising content across two cloud service providers or with local internal storage, and effective monitoring and audit procedures.
