Abstract
A write protection cache (WPC) is introduced between a process and a disk cache on a solid state drive (SSD). The cache provides a holding area, and only data that has been seen more than once is committed to the disk cache. The WPC provides a layer of protection over the data on the disk by avoiding unnecessary writes to the drive. This protection is accomplished by only committing to disk the data or chunks that is seen more than once by a wide area network (WAN) process.
