Abstract
A file storage method and device are provided. The method includes: receiving a storage request for a to-be-stored file (S101); determining a target key for storing the to-be-stored file (S102); obtaining to-be-stored metadata of the to-be-stored file according to the determined target key (S103), wherein the to-be-stored metadata includes: fixed sub-metadata and variable sub-metadata; and storing the to-be-stored metadata in a metadata database, storing the fixed sub-metadata in a name of the determined target key, storing the variable sub-metadata in a preset storage area corresponding to the determined target key, and storing the to-be-stored file in a value of the determined target key (S104). By applying the file storage and device, the recovery of metadata is effectively ensured, while a storage space of a storage terminal is saved.
