Abstract
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.
