Abstract
Transferring data from a local storage device to a remote storage device includes providing a first portion of data to a cache memory of the local storage device, marking the first portion of data as write pending, and, in response to transferring a second portion of data related to the first portion of data prior to the first portion of data being transferred to the remote storage device, transferring the first and second portions of data from the local storage device to the remote storage device. The data may be transferred using RDF format. The first portion of data may be a first block and the second portion of data may be a second block and the first and second blocks may be part of a same sector of data. Transferring the data may also include setting a wpmode flag in response to the first portion of data not being transferred when a request to transfer the second portion of data is made. Transferring the data may also include, in response to the wpmode flag being set, transferring additional data from the local storage device to the remote storage device. The additional data may include data that has also been marked as write pending.
