To restore a bag, find the intellectual object you want to retrieve and click the Restore Object button. This adds a restoration task to the work queue, which you can monitor by clicking the Processed Items tab, or by calling the Items endpoint of the Member API. The restoration process can take anywhere from a few minutes to a few hours, depending on the amount of traffic our system is handling and the size of the bag. Larger bags always take longer to restore, because we calculate md5 and sha256 checksums on the bag's contents. When we restore a bag, we retrieve all of the intellectual object's files from long-term storage, verify the checksums, reassemble the bag, write the manifests, tar up the bag, and leave it in your receiving bucket. When that's done, the Processed Items list will show your bag with a green background, with Action = Restore, Stage = Resolve, and Status = Success, like the first item in the list above. It's up to you then to retrieve and delete the item from your restoration bucket. Your restoration bucket for the demo system is: For the production system, it's: Replace <institution.domain> with your organization's domain name. For example, virginia.edu, jhu.edu, etc. You can download your bags using Amazon's S3 CLI tools, or by integrating one of Amazon's S3 client libraries into your own tools, or by using APTrust's partner tools.
