Abstract
A computer-implemented method for enhancing data transfer is disclosed. The method starts with capturing a snapshot of a storage volume and creating a snapshot volume in response to receiving a request for backing up data from the storage volume of a storage system. Upon receiving a write request for writing a new block to a block location of the storage volume while the storage system is performing a backup operation from the snapshot volume to a target storage system, the storage system performs data preservation for the block location only if the block location to be written is not free, otherwise the new block is written to the block location of the storage volume based on the write request without preservation.
