摘要

PURPOSE: A method for providing continuous data protection about virtual volume, a method for generating restoring instant about virtual volume, and a system providing the continuous data protection about the virtual volume are provided to select a PiT instant by distinguishing PiT instant having the latest generating time before restoring etching according to a reception of an appointed restoration time.;CONSTITUTION: A system conceptually divides a virtual volume into the same size of chunks. The system conserves content of the virtual volume. The system prohibits direct recording access about the virtual volume in a first appointed time(604). The system generates a first PiT(Point-in-Time) instance about the virtual volume in the first appointed time(606). If one is modified among chucks, the system updates the first PiT instance(608).;COPYRIGHT KIPO 2011
