Abstract

The invention provides a periodic data backup method and system, a storage medium and equipment, and the method comprises the following steps: distributing a main volume locally and distributing an auxiliary volume remotely, and creating a difference bitmap with a binary bit at a main volume end; starting a period and traversing binary bits in the difference bitmap, and synchronizing the first data of the corresponding main volume data bit to the auxiliary volume based on the queried binary bit value being a preset binary number; and in response to the fact that a second data request is written into the data bit of the main volume in the synchronization process and the value of the binary bit in the difference bitmap is the binary number, performing synchronization processing and writing processing. According to the invention, the difference data is backed up to different places at fixed time intervals, so that the problem of low data backup efficiency caused by synchronous backup of the data locally and remotely in the prior art can be solved, the data backup efficiency is improved, and the consistency of the local data and the remote data is ensured.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a method, system, storage medium and equipment for periodically backing up data. Background technique [0002] During the use of storage devices, it is not only necessary to provide data storage, but also to provide data disaster recovery backup. In order to avoid damage to storage devices by natural disasters such as floods and earthquakes, data backups will be performed in different places. If synchronous data backup is performed in different places, the delay will be longer due to the distance, which will affect the efficiency of the mainframe business. Contents of the invention [0003] In view of this, the object of the present invention is to propose a method, system, storage medium and equipment for periodically backing up data, so as to solve the problem of low data backup efficiency caused by synchronous backup of data locally and in different places in the prior art...
