Problems solved by technology

At present, the amount of data is increasing exponentially. However, computers, whether it is hardware or software, will inevitably fail. Once a failure occurs, it is likely to cause data (especially important data) loss. For individual users or business users cause irreparable loss

Embodiment Construction

[0040] For individual users or corporate users, the security and comprehensiveness of data is very important, which requires data to be reliably stored and recalled. However, the reliability of the data will be affected in the following two situations: in one case, the computer system is down due to abnormal failures caused by incorrect operation and management; in the other case, new hardware needs to be installed due to computer system maintenance and upgrades Or the software shuts down normally. Reliable storage of data requires nodes to provide uninterrupted data services in the above two situations.

[0041] However, the inventor found through research that if only storing data in the disk space of a node, it is difficult to meet the user's demand for data storage reliability. Therefore, it is urgent to provide a reliable data storage method even if the data storage space fails. , Can also obtain complete data, and will not affect the user to read and use the data generated...

Abstract

The embodiment of the invention discloses A method and apparatus for data storage. When there is a data storage demand, the method comprises the following steps: in response to a write request, a master node acquires a mirror standby node of the master node; The write request includes data to be written; The master node writes the data to be written into the master node and the mirror standby noderespectively. If the master node receives the write completion instruction sent by the mirror standby node, it is determined that the write of the data to be written is successful. In this way, the corresponding mirror backup node can be set in advance by the master node, The data written into the primary node is simultaneously written into the mirror standby node, which ensures the availabilityand integrity of data in the mirror standby node even when the primary node fails or the data is corrupted, improves the reliability of data storage, and provides a more secure and effective data storage service for users.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for data storage. Background technique [0002] With the continuous development of the information age, the use of computer systems to provide individual users or corporate users with timely and reliable information and services has brought great convenience to individual users or corporate users to a certain extent. At present, the amount of data is increasing exponentially. However, whether the computer is its hardware or software, it will inevitably fail. Once it fails, it is likely to cause the loss of data (especially important data) for individual users or corporate users. Bring irreparable losses. [0003] Therefore, it is urgent to provide a reliable data storage method to ensure that when data is damaged or the space for storing data fails, there is still complete data for users to use. Summary of the invention [0004] In order to solve the above...
