发明名称 Systems and methods for preserving deduplication efforts after backup-job failures
摘要 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.

主权项 1. A computer-implemented method for preserving deduplication efforts after backup-job failures at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising: identifying a deduplicated data system that reduces redundant data storage by storing and referencing a plurality of deduplicated data segments, wherein the deduplicated data system reclaims storage space by deleting data segments that are not referenced from the deduplicated data system; identifying a backup job that backs up data to the deduplicated data system, wherein a first performance of the backup job: causes the deduplicated data system to store at least one new data segment that is 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, wherein failure of the first performance of the backup job causes the new data segment to not be referenced within the deduplicated data system; causing the deduplicated data system to wait at least until a second performance of the backup job occurs by causing the deduplicated data system to retain the new data segment until the second performance of the backup job occurs successfully despite the new data segment being not referenced.
