Problems solved by technology

[0002] With the development of new technologies such as cloud computing and big data, the security requirements for the storage of large amounts of data are getting higher and higher. When one device fails, the business will not be affected, but if both storage devices fail or when the data is damaged by human misuse, virus damage, etc., the data will be lost, which will cause very serious consequences

Abstract

The invention discloses a method, system and device for creating a snapshot of a storage active-active volume and a storage medium, and the method comprises the following steps: responding to a storage triggering snapshot, and writing data in a cache into two storages containing the active-active volume at the same time; recording data received by the double active volumes, and judging whether twostored and sent confirmation characters are received or not; creating a snapshot data pointer table based on the recorded data in response to receiving the acknowledgement characters sent by the twostorages; and synchronizing the snapshot data pointer table to the two stores to form a snapshot volume. According to the method, the system, the device medium for creating the snapshot of the storagedual-active volume, and the medium, the snapshot data pointer table is synchronized to the two storages to form the snapshot volume, so that the snapshot of the dual-active volume can be simultaneously created on the two storages of the dual-active volume, and the data consistency is kept.

Description

technical field [0001] The present invention relates to the field of computer technology, more specifically, to a method, system, computer equipment and readable medium for creating and storing snapshots of active-active volumes. Background technique [0002] With the development of new technologies such as cloud computing and big data, the security requirements for the storage of large amounts of data are getting higher and higher. When one device fails, the business will not be affected, but if both storage devices fail or when the data is damaged by human misuse or virus, the data will be lost, which will cause very serious consequences. Contents of the invention [0003] In view of this, the purpose of the embodiment of the present invention is to propose a method, system, computer equipment and computer-readable storage medium for creating and storing snapshots of active-active volumes, by synchronizing the snapshot data pointer table to two storages to form a snapsho...
