Abstract
A computer-implemented method for repairing corrupted data segments in deduplicated data systems may include (1) identifying a corrupted data segment within a deduplicated data system, (2) locating backed up versions of a first file and backed up versions of a second file, (3) analyzing a first pattern with which the backed up versions of the first file reference the corrupted data segment and a second pattern with which the backed up versions of the second file reference the corrupted data segment, (4) determining that a first location within an instance of the first file is more likely to include a non-corrupt instance of the corrupted data segment than is a second location within an instance of the second file, (6) retrieving the non-corrupt instance of the corrupted data segment from the first location, and (7) repairing the corrupted data segment. Various other methods, systems, and computer-readable media are also disclosed.
