Problems solved by technology
[0006] The above method has the following disadvantages: low-level private cloud storage with as little or no compression as possible
However, the private cloud undertakes the task of storing data with high availability and performance requirements. Some files are frequently accessed, and repeated compression and decompression will cause a lot of overhead, which will lead to higher delays, while other files will be the opposite.
Using the same compression method for files with different states, the effect will not be ideal

Embodiment Construction
[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0047] Compression method introduction:
[0048] The Huffman compression method has a shorter compression time and a higher compression ratio (about 0.6), and is suitable for storage that mainly writes files.
[0049] The LZ77 compression method has a shorter decompression time and a higher compression ratio (about 0.6), and is suitable for storage that mainly reads files. However, the large gap between compression time and decompression time is not beneficial in some cases. For example, when out of 10 requests, 9 requests are for reading and 1 request is for writing, then, according to the data in Table 1, the LZ77 compression method will take 0.477 seconds, while the Huffman compression method will take 0.2 seconds. It can be seen that , at this time, using the LZ77 compre...

A data storage method for a hybrid cloud, belonging to the technical field of digital information transmission, comprising the following steps: step 1, establishing a hybrid cloud; step 2, the cache manager processing requests from users; step 3, the cloud manager Access the public cloud storage and download the file to the cache manager; step 4, the cache manager judges whether the file needs to be compressed, and determines the specific compression method used when the file needs to be compressed; step 5, the cloud manager determines to save to Compression method for all files in public cloud storage. This solution improves the performance of the private cloud of the hybrid cloud and saves the cost of the public cloud by combining different compression methods. The private cloud makes compression scheme decisions for each miss request based on file characteristics and lists. The public cloud makes compression scheme decisions for all stored files. This scheme finds a set of compression methods to minimize the cost while satisfying the response bound time requirement.
Description
technical field [0001] The invention belongs to the technical field of digital information transmission, and in particular relates to a hybrid cloud data storage method. Background technique [0002] Hybrid cloud usually includes a public cloud and multiple private clouds, which combine the respective advantages of public cloud and private cloud. Hybrid cloud can use public cloud as a platform for private cloud data backup, cloud data processing, and remote data access, and private cloud As a platform for hot data storage. [0003] The Chinese patent with publication number CN102263825A discloses a hybrid cloud storage system data transmission method based on cloud location, which automatically adopts different data transmission methods for different cloud environments by analyzing cloud storage nodes and cloud client cloud locations , while meeting the high performance of data transmission in the private cloud environment, as well as the high bandwidth utilization and high...
