In some embodiments, a distributed data set is stored across a group of storage devices. Data from a selected storage device in the group are reconstructed and stored in a spare location. Host access requests associated with the data are serviced from the spare location along a first data path while the data from the spare location are concurrently transferred along a different, second data path to a replacement storage device maintained in an offline condition using a progressive (iterative) copyback process. The replacement storage device is thereafter transitioned to an online condition responsive to the transfer of the data to the replacement storage device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nondisruptive device replacement using progressive background copyback operation","description":"Apparatus and method for managing multi-device storage systems.
