Abstract

The invention provides a method and device for realizing remote replication consistency. A main storage end maps a plurality of segmented storage volumes to an application of a host, so as to enable the application to write data into the plurality of storage volumes; the plurality of storage volumes are transmitted to a standby storage end at the main storage end so as to perform first data backup, and then snapshot operation is periodically executed on all the storage volumes of the main storage end at the same time; in response to the snapshot at a certain time point, the facts that the datain the storage volume of the main storage end is not wrong and data change exists compared with the snapshot at the previous time point are recorded, and all the changed data are transmitted to the standby storage end for backup; and in response to the snapshot at a certain time point, the fact that the data in the storage volume of the main storage end has an error is recorded, and the data transmission is suspended from the main storage end to the standby storage end. According to the invention, snapshotting can be periodically carried out on the data of the main storage end to detect whether the data has errors or not, so that the data consistency and security are improved.

Description

technical field [0001] The present invention relates to the field of computers, and more particularly, to a method and device for realizing remote replication consistency. Background technique [0002] With the development of new technologies such as cloud computing and big data, a large amount of data is generated, and the requirements for data security are getting higher and higher. In order to ensure data security, we often use remote replication to solve data protection problems. When multiple storage volumes are provided to applications, the usual means of volume remote replication can no longer guarantee data consistency. For example, when a problem occurs in one of the volumes, other volumes are still transmitting data to the remote end at this time, which cannot be guaranteed at this time. The data is completely synchronously transmitted to the remote end, and the storage backup of the data to the remote end is meaningless. [0003] Due to the rapid development and...
