Storage method and storage device

Abstract

The invention discloses a storage method and a storage device. The storage method and the storage device are used for a storage architecture. The storage architecture comprises an application unit and at least two storage groups. The storage method includes: receiving the data from the application unit; dividing the data corresponding to the same data index into at least two data items; adding a time stamp to each data item; storing the at least two data items in at least one of the two storage groups according to the writable state of the at least two storage groups. The storage method and the storage device realize the high data disaster tolerance and access disaster tolerance, simultaneously realize the preferable load balancing, and improve the agility and availability of the storage architecture.

Description

【Technical field】 [0001] The invention relates to the field of fault-tolerant storage of computer data, in particular to a storage method and a storage device. 【Background technique】 [0002] With the popularization and rapid development of the Internet, the circulation load is also increasing. Therefore, the storage architecture needs to have stable characteristics, so that users will not have problems when reading or writing data. [0003] Please refer to figure 1 , which is a block diagram of a storage architecture in the prior art. The storage architecture includes an application unit 10 , a storage group 12 and two storages 14 , 16 . The application unit 10 is, for example, a user end, and the storage group 12 is used to manage the two storages 14 , 16 . In the storage architecture, the two storages 14, 16 store the same data. When one of the two storages 14, 16 fails, the other has safe and correct data for the application unit 10 to read. This method of using backu...

Problems solved by technology

Since a key corresponds to a value, that is, to a data list, no matter adding, updating or deleting a certain data in the data list, the entire data list must be read and then written to the entire data list, which wastes fault-tolerant storage time and Reduce the efficiency of storage architecture

[0008] Therefore, it is necessary to propose a new technical solution to solve the technical problem that the application unit 10 cannot write data when the above-mentioned storage group 12 is read-only, and after adding, updating or deleting data, the entire data list must be read. Then write the entire data list, resulting in technical problems with poor storage architecture efficiency
