Abstract
A computer-implemented method for preserving deduplication efforts after backup-job failures may include (1) identifying a deduplicated data system that reduces redundant data storage by storing and referencing a plurality of deduplicated data segments and reclaims storage space by deleting unreferenced data segments from the deduplicated data system, (2) identifying a backup job that backs up data to the deduplicated data system, causes the deduplicated data system to store at least one new data segment available to be referenced within the deduplicated data system, and fails after the deduplicated data system stores the new data segment within the deduplicated data system causing the new data segment to be unreferenced within the deduplicated data system, and (3) causing the deduplicated data system to retain the new data segment until the backup job is retried despite the new data segment being unreferenced. Various other methods, systems, and computer-readable media are also disclosed.
