• Fixity Service: In order to ensure that data in the cloud remains viable, this service allows users to check the bit integrity of content stored within DuraCloud and includes many configuration options to fit various usage needs.• Bulk Image Conversion Service: This service handles the conversion of large numbers of images files from one format into other. The server process management is handled by utilizing Hadoop, which allows the conversion to run over multiple servers of varying sizes, thereby increasing the overall throughput. Users with a large number of images stored in DuraCloud will find this service particularly useful.• Sync Tool Option (-e): The Sync Tool allows users to easily move content from the local system into DuraCloud. This new feature allows the Sync Tool to exit when all files are synchronized, rather than continually monitoring the system for changes.• Multi-Delete Feature: To make managing large and complex data sets easier, DuraCloud now provides a simple way to delete groups of content items and spaces in one step.
