The invention provides a distributed data storage method and device. The method includes: invoking a preset virtual storage area when a storage instruction of storing a data object is received; then receiving divided data blocks of the data object, and storing the data blocks into the virtual storage area; acquiring meta information of each data block, which is stored in the virtual storage area,after all the data blocks of the data object are stored in the virtual storage area; and then integrating the acquired meta information to obtain index information of the data object, and utilizing the index information of the data object to replace index information of the virtual storage area to complete storage operations of the data object. Therefore, according to the embodiment of the invention, the data object is already divided into the multiple data blocks when the data object is stored, thus effects of receiving all the data blocks at the same time in parallel, and storing each received data block into the virtual storage area can be realized, and storage efficiency of the data object is effectively improved.
