NetBackup deduplication components
DescriptionComponent
The PureDisk plug-in is the data interface to the NetBackup
Deduplication Engine on the storage server. The PureDisk plug-in
does the following:
Separates the files metadata from the files content.
Deduplicates the content (separates files into segments ).
Controls the data stream from NetBackup to the NetBackup
Deduplication Engine and vice versa.
The plug-in runs on the deduplication storage server. The plug-in
also runs on load balancing servers and on the clients that
deduplicate their own data.
PureDisk plug-in
The NetBackup Deduplication Engine is one of the storage server
core components. It stores and manages deduplicated file data.
The binary file name is spoold, which is short for storage pool
daemon; do not confuse it with a print spooler daemon. The
spoold process appears as the NetBackup Deduplication Engine
in the NetBackup Administration Console.
