Upon receipt of a signed FTP contract, Ingram Data Services will prepare a backlist for your initial data load. Depending on your subscription, backlist data will be provided for bibliographic information, descriptions, and images. (Note: At this time, we cannot provide a backlist for JPG 648 or JPG 1000 images.)
You will first ingest any backlists into your system, and then you will need to ingest any delta or add/delete files in date order. (Note: It is imperative that you ingest the files in date order to ensure that the older information doesn’t overwrite newer information.) Deltas should be processed before deletes. Please see the article on Maintaining Data Integrity for more detail.
Backlists are generally made available to you via a temporary FTP folder. An email notification will be sent when the backlist preparation is complete.
If you have fallen out of sync with your data updates and require a backlist to refresh your data, please contact data.services@ingramcontent.com.
