Abstract: Techniques and mechanisms described herein facilitate the restoration temporal locality in global and local deduplication storage systems. According to various embodiments, when it is determined that cache memory in a storage system has reached a capacity threshold, each of a plurality of data dictionary entries stored in the cache memory may be associated with a respective merge identifier. Each data dictionary entry may correspond with a respective data chunk. Each data dictionary entry may indicate a storage location of the respective data chunk in the storage system. The respective merge identifier may indicate temporal locality information about the respective data chunk. The plurality of data dictionary entries may be stored to disk memory in the storage system. Each of the stored plurality of data dictionary entries may include the respective merge identifier.
