A file system executing on a computing device may store a placeholder for a file on secondary storage of the computing device. The placeholder may comprise a sparse data stream containing none or some of the data of the file and information which enables the remotely stored data of the file to be retrieved from the network. As some or all of the data for the file is being stored remotely, the computing device may rely on a storage virtualization provider to create metadata for the file. Thus, the file system executing on the computing device may receive, from the storage virtualization provider, a request to store metadata associated with the file. In response to this request, the file system may store the metadata as a Binary Large Object (BLOB) in a secondary data stream of the placeholder for the file.

This invention relates to the field of data processing technology and discloses a hybrid storage access scheduling method, system, and medium for storage virtualization. The method includes: collecting write access requests, as well as snapshot chain depth, hot flip count, and time interval. The urgency of the write access requests is determined, and it is judged whether temporary acceleration processing conditions are met. When met, a temporary acceleration mapping relationship is established, directing the access requests to the temporary acceleration mapping relationship. The access frequency of the target logical block segment, the write-back status of the high-speed storage layer, and the amount of additional writes in the snapshot chain are collected to determine whether the temporary acceleration mapping relationship meets the formal migration conditions. When the formal migration conditions are met, the temporary acceleration mapping relationship is converted into a formal mapping relationship. Otherwise, the temporary acceleration mapping relationship is revoked while the primary mapping relationship remains unchanged. This application improves the response to high-urgency write accesses and the smoothness of migration while maintaining the stability of the primary mapping relationship.
