A data manipulation method of a logical volume manager is applicable to data management of dependent snapshot volumes (SVs) of a logical volume manager. The data management method includes the following steps generating a plurality of SVs, defining the SV generated at first as a first SV, defining the SV generated at last as a last SV, and defining the rest SVs as middle SVs; selecting a middle SV; combining content stored in the selected middle SV into a neighboring SV; according to the combined SV, combining meta-data of the selected middle SV into meta-data of the middle SV; deleting the selected middle SV. The logical volume manager does not need copy the data again, thereby saving access time in data management.
