Abstract

An application consistent data protection method provides application-assist and replication-technology neutral mirroring that ensures that a remote data copy is application-consistent. The method comprises a coordination protocol to coordinate application hosts across heterogeneous hosts and heterogeneous storage devices. The method utilizes a disk layout and data record format that enables use of an underlying replication ability of a storage device, minimizing development cost and utilizing customer investment. The method comprises on-demand consistency point initiation to minimize performance impact and maximize system resource usage. The method can be applied to both synchronous and asynchronous mirroring and can be incorporated into any virtualization device.

Description

technical field [0001] In general, the present invention relates to the field of data protection and backup. Specifically, the present invention relates to protecting data through remote mirroring in an integrated system including heterogeneous hosts and heterogeneous storage devices. Background technique [0002] Data protection is critical to business. This tendency is becoming more pronounced due to the requirement for adaptability in regulation. The US Securities and Exchange Commission recommends that business be restored within 24 hours of a system failure. This requirement for incident recovery and backup drives the need for advanced data protection technologies. Such differences in technology can be very important to vendors as well as consumers. Currently, there are various traditional data protection solutions in the market, ranging from backup to remote mirroring. Additionally, many data storage devices and data storage products include data protection feature...
