Abstract
Methods, systems, and computer programs are presented for replicating snapshot data between network storage devices. One method includes an operation for detecting a read request for a data block of a volume in a storage device, the volume being stored in disk storage and cached in cache memory. The data block is read from the cache memory if the data block is in the cache memory, otherwise, the data block is read from the disk storage. When the data block is not stored in the cache memory and the read request is not for replicating the data block to a another storage device, the data block read from the disk storage is cached in the cache memory. However, the data block is not cached in the cache memory when the data block is being replicated to the other storage device. Afterwards, the read request is completed.
