Abstract

A method of protecting cache data of a storage system is disclosed, which is for protecting cache data of a storage system with a battery backed function. The present invention reserves a reserved zone in a system random access memory (RAM) for recording disk cache item information. When the storage system is powered-off, data stored in the system random access memory would be protected through the battery backed function. When the storage system is re-activated, data stored in the disk cache of the system random access memory would be reserved through the information stored in the reserved zone. After the storage system is re-activated, the data stored in the disk cache of the system random access memory is written into a corresponding block device, so as to achieve a power-off protection function to the data stored in the disk cache of the system random access memory.
