Abstract
Mirroring write operations from a local storage system to a remote storage system. Such mirroring comprises intercepting I/O transactions to a storage disk of the local storage system, identifying a series of write transactions to said storage disk from the intercepted I/O transactions, storing an exact copy of the series of write transactions within a series of files that are created on a file-system of the local storage system, and transmitting the series of files from the local storage system to the remote storage system to accommodate a reproduction at the remote storage system of the series of write transactions as issued to said storage disk of the local storage system.
