Abstract
Embodiments of the present disclosure provide a method and device for a storage system. The method may include: replicating, through a first replication process, data in a first storage device to a second storage device to obtain a data replica; replicating, through a second replication process, metadata of the data to the second storage device to obtain a first metadata replica; replicating, in the second storage device through a third replication process, the first metadata replica to obtain a second metadata replica; and performing data recovery based on the data replica and the second metadata replica.
