A method for migrating a backup system includes: storing a backup copy from a first backup system to a second backup system, wherein the first backup system is used to store historical backup copies of an application system, and the second backup system is used to store future backup copies of the application system; dividing the backup copy into multiple backup extents; receiving a backup request for backing up a data object in the application system; and backing up, based on a comparison between the data object and the multiple backup extents, the data object to the second backup system to form a backup copy corresponding to the data object."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, device, and computer program for migrating backup system","description":"The present disclosure relates to a method, a device, and a computer program for migrating a backup system.
