Embodiment Construction

[0063] A preferred embodiment of the present invention will be described in detail below in conjunction with the drawings.

[0064] See first figure 1 and figure 2 , are respectively a system architecture diagram and a system schematic diagram of the first embodiment of the present invention. Such as figure 1 As shown, the present invention mainly discloses a hierarchical cloud storage system 1 (hereinafter referred to as the cloud storage system 1 for short in the specification), the cloud storage system 1 mainly includes at least one local storage device 2 and a The cloud storage unit 3, wherein the local storage device 2 and the cloud storage unit 3 are connected to each other through a network.

[0065] In this embodiment, the local storage device 2 can mainly be a cloud storage gateway (Cloud Storage Gateway, CSG). The CSG is a device capable of connecting to the cloud drive through the network. It provides an access interface that can access the file system of the c...

Abstract

The invention discloses a hierarchical cloud storage system and an access method thereof. The cloud storage system comprises a local storage device and a cloud storage unit; and the local storage device includes a plurality of hierarchical storage units. After a file is written into the local storage device, the cloud storage system moves the file from the original storage unit to a storage unit at the next hierarchy for storage timely and establishes a symbolic link corresponding to the new position of the file in the original storage unit. According to the invention, the cloud storage unit serves as the storage unit at the last hierarchy in the cloud storage system and all files in the cloud storage system are moved to the cloud storage unit finally. Therefore, if the cloud storage system includes another local storage device, the file in the cloud storage unit can be shared by two local storage devices.

Description

technical field [0001] The present invention relates to a storage system and its access method, in particular to a hierarchical cloud storage system realized by combining a local storage device and a cloud storage unit, and an access method of the hierarchical cloud storage system. Background technique [0002] In order to meet the data access requirements of users, a hierarchical storage system (Hierarchal storage system, HSS) is currently available on the market. The HSS is mainly composed of storage media of different levels, so as to store data through the concept of hierarchy. For example, one HSS may include one or more random access memories (Random Access Memory, RAM), solid state disks (Solid State Disk, SSD) and hard disk drives (Hard Disk Drive, HDD), etc. at the same time. [0003] As mentioned above, the HSS will store the newly written data in the RAM to quickly complete the storage operation; store the more frequently accessed data in the SSD to make the data...
