The embodiment of the invention discloses a reconstruction method for a data storage failure. The reconstruction method comprises the following steps that data failed in insertion is registered in a cache region; the data registered in the cache region is aggregated according to service identification information carried by the data; the aggregated data is reinserted in batches. According to the method, by registering the data failed in insertion in the cache region and aggregating the data in the cache region, the total amount of the data failed in insertion is decreased, and the information throughput pressure on storage equipment is decreased; by reinserting the aggregated data in batches, reinserting can be sequentially conducted, the pressure on courses is reduced, and data reinsertion is achieved on the condition that normal operation of services is not affected.
