File storage method and device, equipment and storage medium

The invention relates to a file storage method, device and equipment and a storage medium, and the method comprises the steps: receiving at least part of file content sent by terminal equipment and information of a plurality of storage nodes for storing copy files corresponding to the at least part of file content, and the plurality of storage nodes comprise a target storage node; splitting at least part of the file content into a plurality of file slice groups, wherein each file slice group comprises at least one file slice; and respectively copying the plurality of file slice groups to different storage nodes except the target storage node in the plurality of storage nodes, wherein the number of the plurality of file slice groups corresponds to the number of the different storage nodes. Therefore, the file content is backed up, the reliability and availability of the file can be improved, and meanwhile, in the file backup process, the file content is copied to different storage nodes in the form of the file
