A first entry is located in a volume control table for the logical address to write indicating a version number and a first physical location. The write data is written to a second physical location in the storage device. A second entry is added to the volume control table for the logical address in response to preserve mode being enabled. In response to determining that the preserve mode is enabled, the volume control table is updated to have one of the first and second entry for the logical address point to the second physical location and indicate a current version and to have the first or second entry not indicating the current version to indicate the first physical location and a previous version."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Providing versioning in a storage device","description":"Provided are a computer program product, system and method for managing Input/Output (I/O) requests to a storage device.
