Abstract
According to some embodiments, a backup storage system receives a request from a client for writing a data segment associated with a file object stored to a storage system. In response to the request, the system writes the data segment to one of many storage units of the storage system. The system determines whether the data segment is associated with a file region of the file object that is frequently accessed. The system writes the data segment in a first of many of write-evict units (WEUs) stored in a solid state device (SSD) operating as a cache memory device for caching data, after it is determined that the data segment is associated with the frequently accessed file region.
