A data access method, system, device and storage medium are disclosed. In a case where there are data access hotspots in the original snapshot copy, multiple storage nodes are scheduled to concurrently read a data file of the original snapshot copy into memories of the multiple storage nodes, which can improve the efficiency of the storage nodes in reading the data file of the original snapshot copy. Based on data files in the memories of the multiple storage nodes, data to be accessed is provided to the instance, and memory caches of the multiple storage nodes may be used to accelerate the reading speed of the data to be accessed and reduce the data access delay. The multiple storage nodes are scheduled to dynamically generate a new snapshot copy based on the data files in the memories for a cloud disk to reference.

Data access method and system, device, and storage medium

Synchronizing hard link files on master and replica servers includes providing master and replica server hard link file snapshots. The master server hard link file snapshot includes a listing of hard link file names from a root directory of the master server. The replica server hard link file snapshot includes a listing of hard link file names from a root directory of the replica server. The master server hard link file snapshot and the replica server hard link file snapshot are compared. A synchronized hash map linked list may be generated responsive to the comparison. The synchronized hash map linked list includes a listing of group identifications corresponding to physical data files at the master server. For each group identification in the synchronized hash map linked list, the synchronized hash map linked list includes at least a hard link file name from the root directory of the master server.
