Publication number: 20140129765Abstract: Data back-up and recovery methods for DRAM SSDs and other high performance disks are provided. During operation, write events to the DRAM SSD are asynchronously backed-up onto a back-up HDD storage disk from an in-memory buffer. Should a DRAM SSD failure occur, the system can continue to operate, albeit at a lower performance, using the back-up HDD storage disk. Should the main power fail, data remaining in the in-memory buffer is flushed to the back-up HDD storage disk and writing events that did not make it to the in-memory buffer due to insufficient space are incrementally backed-up from the DRAM SSD to the secondary storage. Once power returns from the main power, data from the back-up storage disk and the secondary storage are transferred to the DRAM SSD.Type: ApplicationFiled: November 7, 2012Publication date: May 8, 2014Applicant: TAEJIN INFO TECH CO., LTD.Inventor: Byungcheol CHO
