FAULT PREDICTION MODEL BASED AGGRESSIVE CHECKPOINTING METHOD

摘要

The present invention relates to a check pointing method based on defect prediction. step; (b) The defect occurrence prediction time point provided by the predetermined defect occurrence prediction model is divided by the checkpoint interval and the total Determining the number of check points; (c) the entire check using the system error rate of the defect occurrence prediction model Calculating the number of checkpoints to be performed in the section before the occurrence of the defect from the number of points; (d) all check points above Checkpoints to be performed in the defective section by excluding the number of checkpoints to be performed in the section before the defect occurrence from the number Calculating the number of twitches; (e) Schedule according to the number of checkpoints calculated in step (c) above in the section prior to the occurrence of the defect. Storing a system snapshot by performing a checkpoint at an interval; (f) In the defect generation section, Storing a system snapshot by performing checkpoints at regular intervals according to the calculated number of checkpoints; And (g) In the event of a system failure, the step of rolling back the system to a time point closest to the time point of the failure using the system snapshot; It is characterized by including.
