Data Domain Cloud Tier - Backup Here, Backup There, Deduplicated Everywhere!

Explore a conference talk detailing Data Domain's cloud tier capability for its on-premises storage appliance, focusing on key innovations that support essential customer interactions. Learn about architectural changes and new algorithms addressing the impact of deduplicated storage and cloud object storage challenges. Discover how customers estimate space savings, transfer files to and from the cloud, and manage file deletion in the cloud tier. Gain insights into real-world deployments, including examples of customers moving over 20PB of logical data to the cloud tier and achieving compression factors of 40× or more, resulting in significant cost savings. Delve into topics such as file representation, active and cloud tier architecture, deduplication system challenges, physical scanning, efficient data seeding and incremental transfers, and dead data cleaning in the cloud tier. Examine the evaluation methodology, field analysis, and summary of results from this USENIX ATC '19 presentation.
