A log-structured storage method and a server, where the method includes obtaining a current incremental update of an object when the object is updated, wherein a current version of the object is stored in a log-structured storage area of the server, determining whether there is a previous incremental update of the object stored in the log-structured storage area, writing the current incremental update as a latest incremental update in the log-structured storage area when there is no previous incremental update of the object stored in the log-structured storage area such that the utilization of memory can be improved.
