Figure 4: HP StorageWorks Disk-based Backup

Where does HP Data Protector software fit into the picture?

Deduplication, today, is a feature provided by HP StorageWorks Virtual Library Systems and HP StorageWorks D2D Backup Systems and other vendors’ hardware.

Deduplication on the in the previously mentioned paragraph storage devices happens either as “Inline deduplication” (Dynamic deduplication) or as “Post-Process” (Accelerated deduplication) technique.

Both ways are completely transparent to HP Data Protector software.

HP Data Protector Advanced Backup to Disk Licensing

As of 1st July, 2008, the HP Data Protector Advanced Backup to Disk license will cover the planned/consumed capacity on HP Data Protector file libraries and virtual tape libraries (VTL).

In cases where HP Data Protector software is using the VTL exclusively, it is recommended to license a quantity of Advanced Backup to Disk licenses matching the physical capacity of the VTL. HP calls the physical VTL capacity “usable native capacity.” Other vendors call it “raw capacity.” The new physical size/consumption licensing model does not require compression rates and deduplication ratios to be considered. RAID overhead does not to be considered as well.

The relevant HP Data Protector Advanced Backup to Disk licenses are:

B7038AA capacity license for 1 TB of backup disk storage

B7038BA capacity license for 10 TB of backup disk storage

B7038CA capacity license for 100 TB of backup disk storage
