Services
DuraCloud stores your content in the cloud, but its services do a lot more.
Storage and Preservation Services
Backup and Syncing
It’s easy to use our Duplicate On Demand service to copy your content onto several different cloud storage providers. Simply choose a source location (or “space”) and a space to which content will be duplicated. The service copies all of the content and metadata in the source space to the duplication space, creating the duplication space if necessary.
Our Duplicate on Change service lets you be sure that whenever you upload new content, all the copies we manage for you get the same exact stuff. The duplication happens on change, which means that the service watches for all content that is added or updated in your DuraCloud account, determines if it should be copied to another DuraCloud storage site, and copies the content when necessary. The service places all of the copied content in an identically named space in the secondary storage location. Both of these services are easy to customize with several configuration options.
Health Checkup
We make it easy to verify the integrity of files stored with cloud providers. Our Bit Integrity Checker services let you verify a short list of items or an entire set of content, and it also generates comparative reports. They make it easy to see that uploads have happened flawlessly, and they also make it easy to check in later and stop “bit rot” – the annoying habit files have of changing over time all by themselves.
Our service verifies the integrity of an entire space, or a list of items, by collecting the content checksum values for each item from the underlying storage provider, streaming through each item while recalculating their checksums, and comparing the two listings. The service then generates a report for the space or list that compares both the stored checksum values from the storage provider as well as the computed checksum values. We also offer a Bulk Bit Integrity Checker service for spaces larger than 1 terabyte. This one uses an Amazon Hadoop cluster to determine checksums for all content items in any particular space. And if that’s not enough, we give you several other options to customize our health checkup services, too.
Utilities
We're flexible. We have several command-line utilities that give you more direct ways to put content in DuraCloud, sync several copies, or download from the cloud to your own computer. And because we're based on open source software, our community is creating and sharing more good stuff all the time.
Media and Access Services
Video and Audio Streaming
DuraCloud can stream video and audio files directly from DuraCloud to any internet-linked device. Users like the Media Streamer service because the videos load quickly. You will like it because it doesn't tie up your computers. Our streamer is based on Amazon’s Cloudfront service which uses the Flash Media Server to host streaming files over RTMP in MP3, MP4, FLV, and other formats. Our streaming service is designed to allow for easily embedding media in your web site and has several options for customization.
Image Serving
Our Image Server service uses Djakota, an open source application, to serve up images in the JPEG2000 format directly from cloud storage. It also supports multiple image file types by converting them to the JPEG2000 format on the fly. The images load quickly, and you don't have to tie up space on your own computer to share them. You can pan, tile, and zoom in on your images using our viewer, too.
