About NetBackup deduplication |
|
The following list describes how NetBackup derives unique segments to store:
■The deduplication engine breaks file 1 into segments A, B, C, D, and E.
■The deduplication engine breaks file 2 into segments A, B, Q, D, and L.
■The deduplication engine stores file segments A, B, C, D, and E from file 1 and file segments Q, and L from file 2. The deduplication engine does not store file segments A, B, and D from file 2. Instead, it points to the unique data copies of file segments A, B, and D that were already written from file 1.
