Storing and Protecting Digital Content
This webinar will address best practices in storing digital content and the various aspects of protecting that content. Best practices for storing digital content include maintaining multiple copies of digital objects in at least two locations, with digital objects consisting of files and associated metadata. Protecting digital content is a key responsibility of long term management, and includes everyday concerns such as controlling access and fixity checking, and emergency contingencies such as disaster planning and ensuring business continuity.

Potential Solutions
Archivematica is a free and open-source digital preservation system that is designed to maintain standards-based, long-term access to collections of digital objects. Archivematica is packaged with the web-based content management system AtoM for access to your digital objects.
Archivematica uses a micro-services design pattern to provide an integrated suite of software tools that allows users to process digital objects from ingest to access in compliance with the ISO-OAIS functional model. Users monitor and control the micro-services via a web-based dashboard. https://www.archivematica.org/wiki/Main_Page
DuraSpace is an independent 501(c)(3) not-for-profit organization providing leadership and innovation for open technologies that promote durable, persistent access to digital data. They collaborate with academic, scientific, cultural, and technology communities by supporting projects and creating services to help ensure that current and future generations have access to the collective digital heritage.

Preservica is part of Tessella group, the international analytics, software services and consultancy company. The Preservica active preservation and access technology is available in cloud hosted and on premise Editions and includes a full suite of OAIS (Open Archival Information System) compliant workflows for ingest, management, storage, access and long-term preservation of digital content.

Amazon Web Services (http://aws.amazon.com) includes:
Amazon S3 provides a simple web-services interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, secure, fast, inexpensive infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers.
Amazon Glacier is an extremely low-cost storage service that provides secure and durable storage for data archiving and backup. In order to keep costs low, Amazon Glacier is optimized for data that is infrequently accessed and for which retrieval times of several hours are suitable. With Amazon Glacier, customers can reliably store large or small amounts of data for as little as $0.01 per gigabyte per month, a significant savings compared to on-premises solutions.
MetaArchive is a community-owned, community-led initiative comprised of libraries, archives, and other digital memory organizations. Working cooperatively with the Library of Congress through the NDIIPP Program, they have created a secure and cost-effective repository that provides for the long-term care of digital materials – not by outsourcing to other organizations, but by actively participating in the preservation of members’ own content. http://www.metaarchive.org/

NDSA Levels of Digital Preservation - The “Levels of Digital Preservation" are a tiered set of recommendations for how organizations should begin to build or enhance their digital preservation activities. A work in progress by the NDSA, it is intended to be a relatively easy-to-use set of guidelines useful not only for those just beginning to think about preserving their digital assets, but also for institutions planning the next steps in enhancing their existing digital preservation systems and workflows.

Digital POWRR - Preserving Objects With Restricted Resources
http://digitalpowrr.niu.edu/
While many larger institutions have made considerable headway on digital preservation, many medium and smaller sized institutions have struggled to make similar progress, largely due to a lack of economy of scale. This project will investigate, evaluate, and, at its close, recommend scalable, sustainable digital preservation solutions for libraries with smaller amounts of data and/or fewer resources. Working closely with nationally recognized standards-based vendors of digital preservation solutions, the project will also investigate potential business models that would provide equitable access to digital preservation to libraries of all sizes. This project has produced an incredibly helpful tool grid: http://digitalpowrr.niu.edu/tool-grid/
