When a system receives a request to update a page of a storage device storing database files of a database, the system can update the page and replicate the updated page in a shadow page in a backup queue. The backup queue can store multiple shadow pages, where each updated page can correspond to at most a specified number of shadow pages in the queue. Each shadow page can be associated with a timestamp of a latest update. At pre-specified temporal checkpoints, the system can write the shadow pages in the queue to a backup file in the order of the timestamps. Upon receiving a restoration request, the system can restore the database to a state as of the time of the checkpoint using the backup file."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Checkpoint based progressive backup","description":"Methods, program products, and systems for checkpoint based progressive backup are described.
