A file system for data effective protection
Zhang You-jie · Modern Electronics Technique · 2012
A new file system PSFS(pseudo sequence file system) is presented,which can effectively protect the data removed by mistake.The proposed file system takes a pseudo circular queue as the core to makes full use of the increasing capacity of hard disk,flash disk and other storage device.The deleted files are guaranteed not to be covered when the storage medium have enough space.The structure of the file system is described in detail.A example is used to illustrate its principle and data recovery method.Comparing with the existing data recovery technologies,the proposed method can recover the data more quickly and accurately.
