Symantec 7 用户手册
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.
