Embodiment 1

[0044] The following is an introduction to Embodiment 1 of the periodic asynchronous remote replication method provided by this application, see figure 1 , embodiment one includes:

[0045] S11. Determine the real-time traffic of the first host;

[0046] S12. According to the real-time business volume, use the target formula to determine the target period of the asynchronous remote replication;

[0047] S13. Control the first host to asynchronously and remotely copy the business data to the second host according to the target cycle until the time of the current round of asynchronous remote copying reaches the preset time threshold, and return to S11 to enter the next round of asynchronous remote copying.

[0048] The purpose of this embodiment is to automatically adjust the period of the asynchronous remote replication based on the business volume. The purpose of asynchronous remote replication is to achieve data synchronization. In asynchronous remote replication, the conte...

Embodiment 2

[0054] The following begins to introduce the second embodiment of the periodical asynchronous remote replication method provided by this application in detail, see figure 2 , embodiment two specifically includes:

[0055] S21. Obtain the historical traffic data of the first host; determine the maximum value and the minimum value of the traffic according to the historical traffic data;

[0056] S22. Determine the real-time traffic of the first host; acquire the current period of the asynchronous remote replication of the first host;

[0057] S23. According to the real-time business volume, a target period of the asynchronous remote replication is determined by using a target formula. If the calculated value of the target period is not an integer, the value of the target period is rounded down.

[0058] The above target formula is: t=S-(T_max-T_min) / (Q_max-Q_min)*q, where S is a preset constant, T_max and T_min are the maximum and minimum values ​​of the cycle of asynchronous...

Abstract

The invention discloses a periodic asynchronous remote replication method, the method can flexibly set the period of asynchronous remote replication according to the real-time service volume of a host, set a short period when the service volume is relatively large to avoid data loss, and set a long period when the service volume is relatively small to avoid introduction of unnecessary calculation amount. The period adjustment mode does not occupy extra manpower, the manpower cost can be saved, and the asynchronous remote replication efficiency can be improved. In addition, the invention further provides a periodic asynchronous remote copying device and equipment and a readable storage medium, and the technical effects of the periodic asynchronous remote copying device and equipment and the readable storage medium correspond to the technical effects of the method.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a periodic asynchronous remote replication method, device, equipment and readable storage medium. Background technique [0002] The business volume of existing storage application fields such as banking and the Internet varies greatly at different times of the day. At present, there are two main methods for setting the period of asynchronous remote replication in the storage system. One is to set a fixed period for data synchronization, and the other is to artificially set different periods according to business needs. These two methods have the following disadvantages respectively: [0003] Although the method of fixed period does not require manual adjustment, if the period setting time is short, frequent asynchronous remote replication will cause a lot of unnecessary calculations when the business volume is small or even has no business operations (for example...
