Abstract

A method for selectively replicating data of a main memory, where the data is stored on one or more blocks of one or more logic units of the main memory. The method includes receiving, by a secondary memory, a request to selectively replicate the data of the primary memory. The method also includes executing a command to receive a configurable parameter set of the logic unit. The method also includes selectively copying the one or more blocks storing the data from the primary memory to the secondary memory according to the received configurable parameter set.

Description

technical field [0001] The present invention relates generally to the field of storage systems; more particularly, to a method and system for selectively replicating data in main memory. Background technique [0002] In a storage system, data is usually stored in a block device, and the data in a block device is usually stored in some file system format. In general, a block device is a computer data storage device that supports reading and optionally writing data in fixed-size blocks, sectors, or clusters. Furthermore, data replication is the process of storing data in more than one node such as primary and secondary storage to increase the availability of data and ensure data protection in case of data loss. Therefore, secondary storage is often used to replicate the data present in the primary storage system of the host storage device for security reasons. In one example, both the primary storage system and the secondary storage system may be block devices used for data ...
