Abstract
The system and method described herein may support multiple-layer data replication using a block input/output (“BIO”) structure that an operating system kernel employs to provide an intermediate mechanism between file systems and block devices. For example, the system and method described herein may capture events that occur when the kernel uses the BIO structure to encapsulate input/output requests that will change data on a master block device. As such, a replication mechanism may send the changes encapsulated within the BIO structure to a replay mechanism, which may then replicate the changes on a standby block device to ensure that the master block device and the standby block device have an identical state. Alternatively, a filter may be used to only replicate changes to certain partitions or file system objects on the master block device.
