Abstract: Exemplary embodiments provide various techniques for detecting and correcting corrupted or dangling data object handles. In one example, a method is provided for correcting corrupted data object handles. In this method, a redirector file stored on a first logical data container is accessed. This redirector file includes a forward object handle pointing to a first data object stored on a second logical data container and includes a first checksum of the forward object handle. A second checksum of the forward object handle is determined and a comparison is made between the first and second checksums. If a mismatch is detected, the data objects stored on the second logical data container are scanned to extract backward object handles. A backward object handle can be identified to point back to the redirector file. The forward object handle can then be restored to point to the second data object based on the identification.
