Abstract

The present invention provides an on-line synchronous backup system method and a device thereof. The method comprises: (1) a host device storing, in an on-line synchronous manner, data of a primary memory of the host device to a first memory module through an input/output processor (IOP); (2) when power supply of the host device is cut off, the IOP instructing the first memory module to store the primary memory data to the IOP; (3) the IOP storing the primary memory data so stored therein to a second memory module; (4) when the power supply of the host device resumes, the IOP instructing the second memory module to store the primary memory data, through the IOP, to the first memory module; (5) storing the primary memory data stored in the first memory module to the host device so that the primary memory of the host device may get recovered. As such, the primary memory data that is in process can be stored simultaneously in at least one preset device so that in case of unexpected interruption of power supply, the primary memory data is written into a non-volatile storage device for permanently preserving the primary memory data and when power supply resumes, the primary memory data can be stored back to the system from the preset device to allow the primary memory data to complete restoration, allowing the system to continuously normally work.
