Embodiment Construction

[0041] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0042] see figure 1 , the figure shows a continuous data protection method according to an embodiment of the present invention, including steps:

[0043] Step S101: The server receives the client's log data and stores it in data blocks. After the current data block is full, point the current data block to another data block with available storage space, and continue writing in the other data block ;

[0044] Step S102: the server establishes and maintains a primary index according to the block number of the data block, and establishes and maintains a secondary index according to the time point of the log data in each data block;

[0045] Step S103: the server searches for log data according to the primary index and the secondary index when performing data recovery.

[0046] The embodiment of the present invention proposes to store log data in units ...

Abstract

The invention provides a continuous data protection method and a server. The method comprises the following steps of: receiving log data of a client by the server, storing the log data according to data blocks, when the current data block is full, directing the current data block to another data block with available storage space, and continuously writing at another data block; establishing and maintaining a first-level index according to the number of the data block; establishing and maintaining a second-level index according to time points of the log data in each data block; and searching the log data according to the first-level index and the second-level index when the data is restored. By the method, the log data can be reasonably managed and quick searching and data restoration can be realized.

Description

technical field [0001] The invention relates to the computer field, in particular to a continuous data protection method and server. Background technique [0002] The rapid growth of data and the high availability and security requirements of data have stimulated the development of storage technology. Storage technology has become a key factor in IT infrastructure. Storage network provides an effective hardware foundation for mass storage and sharing of data. In the face of massive data, data protection and disaster recovery are becoming more and more important. However, the original data protection methods, such as tape backup, have disadvantages such as large backup window, long recovery time, poor real-time response, and affecting normal business. meet current needs. Online replication and data redundancy using disks became popular data protection techniques. [0003] Continuous Data Protection (CDP) is a method that can continuously capture or track any changes in the ...
