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...
