Digital Preservation with DuraCloud™

DuraCloud provides members of the Texas Digital Library with a cost-effective and easy-to-use solution for digital preservation. By storing and managing content in multiple geographic locations and with multiple storage options available, members can control their costs, enjoy predictability for service, and rely on known, durable technologies and best practices for ensuring the integrity of the riches of their digital collections.

DuraCloud™ is an open-source technology that facilitates storage of digital content within cloud-based storage providers. It was developed and released under an open-source license by DuraSpace and is hosted by the Texas Digital Library for its member institutions.

How It Works: Spaces, Ingest Tools, and Storage Options

TDL Preservation Storage via DuraCloud

Each TDL regular member receives a “Space” in DuraCloud™ for ingesting content, along with an allowance for “free” storage through DuraCloud™ @TDL based on its membership level. (More about the member allowance here.)

  • TDL members can upload content to DuraCloud™ @TDL via two methods (DurAdmin for single files or DuraCloud Sync for batch upload). Content is uploaded into a “Space” within DuraCloud™ created just for that member. (More about ingestion methods here.)
  • Currently, the DuraCloud™ @TDL offers three different storage options for members — two in the Amazon Cloud and one at the Texas Advanced Computing Center (TACC). By default, content ingested into a DuraCloud™ @TDL space is stored in Amazon S3 storage; copies of the content can be stored in Amazon Glacier and at TACC. Members who do not want to use S3 storage for the long term may request to have the original copy removed from Amazon S3 storage. (More about storage options here.)
  • DuraCloud™ @TDL will, in the future, serve as an ingestion point for content that will be replicated to the Digital Preservation Network.

More about DuraCloud Spaces

DuraCloud™ @TDL users manage preservation in unique, user-managed areas called “Spaces” within the DuraCloud environment. Initially, each institution is allotted a single Space but may request additional Spaces to better manage their content.

  • A Space is a flat file that initially appears on a single storage option (Amazon S3), but which can be replicated to appear in any combination of the three TDL storage options.
  • Initially, all Spaces are available for viewing only by the institutional manager and TDL administrators. However, there are options to make spaces available for public viewing.

TDL Account Setup and Support
