Destination restores the virtual-machine data of purpose end main frame according to the incremental data.
Specifically, can be interrupted according to the size of data of virtual-machine data, the message transmission rate of source to destination, source
These three conditions determination of business duration demand needs after executing snapshot operation, can also determine subsequently newly-generated to source end host
Virtual-machine data beats the time interval and number of operations of snapshot, and the time interval and number of operations equally can be according to above threes
Condition is determined, such as：The virtual-machine data that source end host generates is more, then the time interval is smaller, and number of operations is also got over
It is more.
It should be noted that when determining time interval and executing number, not only carried out according to above three condition true
It is fixed, snapshot operation can also be just executed after the virtual-machine data for detecting source end host generation predefined size, it is more in this way
