Which action is performed by the NetBackup deduplication plug-in?
The NetBackup deduplication plug-in is responsible for performing file fingerprinting actions. This involves reading the backup image, separating it into files, and then further breaking down the files into segments. For each segment, the plug-in calculates a unique hash key, also known as a fingerprint. This hash key uniquely identifies each data segment, enabling efficient deduplication.
I think correct answer is C The deduplication engine, not the plug-in, is responsible for writing data segments into the MSDP containers
Correct answer is C: "NetBackup uses a unique identifier to identify each file and each file segment that is backed up. The deduplication plug-in reads the backup image and separates the image into files. The plug-in separates the files into segments. For each segment, the plug-in calculates the hash key (or fingerprint) that identifies each data segment. To create a hash, every byte of data in the segment is read and added to the hash."
