Systems and methods for repairing corrupted data segments

A system for repairing corrupted data segments, the system comprising:

• a detection module, stored in memory, that detects a corrupted data segment in a backup stored in a data storage system, wherein the detection module detects the corrupted data segment by detecting an offset corrupted data segment, wherein an uncorrupted version of the offset corrupted segment cannot be located using a fixed-length deduplication algorithm;
• an identification module, stored in memory, that identifies at least one additional backup stored in the data storage system that exceeds a predetermined threshold for probability of comprising an uncorrupted version of the corrupted data segment;
• a matching module, stored in memory, that matches at least a portion of a data segment in the additional backup with at least a portion of a data segment adjacent to the corrupted data segment in the backup;
• a location module, stored in memory, that locates, at least in part by examining data adjacent to the matched data segment in the additional backup, the uncorrupted version of the corrupted data segment;
• a repair module, stored in memory, that repairs the corrupted data segment in the backup by using the uncorrupted version of the corrupted data segment located in the additional backup;
• at least one physical processor configured to execute the detection module, the identification module, the matching module, the location module, and the repair module.

A non-transitory computer-readable medium comprising one or more computer-readable instructions that, when executed by at least one processor of a computing device, cause the computing device to:

• detect a corrupted data segment in a backup stored in a data storage system, wherein the one or more computer-readable instructions cause the computing device to detect the corrupted data segment by detecting an offset corrupted data segment, wherein an uncorrupted version of the offset corrupted segment cannot be located using a fixed-length deduplication algorithm;
• identify at least one additional backup stored in the data storage system that exceeds a predetermined threshold for probability of comprising an uncorrupted version of the corrupted data segment;
• match at least a portion of a data segment in the additional backup with at least a portion of a data segment adjacent to the corrupted data segment in the backup;
• locate, at least in part by examining data adjacent to the matched data segment in the additional backup, the uncorrupted version of the corrupted data segment;
• repair the corrupted data segment in the backup by using the uncorrupted version of the corrupted data segment located in the additional backup.
