Title: SYSTEMS AND METHODS FOR HEALING IMAGES IN DEDUPLICATION STORAGE
Abstract:
The disclosed computer-implemented method for healing images in deduplication storage may include (1) detecting that a data segment stored within deduplication storage is corrupted by executing an algorithm on the data segment to generate a numerical identifier for the data segment and determining that the numerical identifier does not match a previously stored numerical identifier for the data segment, (2) checking, during a backup operation, whether a digital fingerprint of a data segment of an image being backed up matches a digital fingerprint of the corrupted data segment that was taken prior to corruption and that is already stored within the deduplication storage, and (3) appending the data segment from the image being backed up to a container that already contains the corrupted data segment rather than replacing the corrupted data segment. Various other methods, systems, and computer-readable media are also disclosed.
