<p>Disclosed are a method for recovering hard drive data, a server and a distributed storage system, which belong to the field of computers. The method comprises: receiving a data recovery request, the request comprising at least one to-be-recovered data sector identity (ID), and finding at least one to-be-recovered data sector according to the at least one to-be-recovered data sector ID; acquiring at least one backup sector ID and a file backup corresponding to the at least one to-be-recovered data sector ID, and finding at least one backup sector according to the at least one backup sector ID; and writing data, from the file backup, that is the same as that stored in the at least one to-be-recovered data sector, into the at least one backup sector. The server comprises: a receiving module, an acquisition module, and a write module. The system comprises: at least two servers, at least one server being a mirror server of the other server; and the other server being the aforementioned server. By means of the technical solutions of the present invention, hard drive data can be recovered rapidly, and the operating cost of an enterprise can be reduced.</p> |
