Archiving Methods; Cartridge Copy - HP StorageWorks D2D - Backup Systems User Manual

• Copy refers to the process that creates an additional copy of the cartridge on the physical tape
storage device.
Backup applications may use similar terminology to describe the processes for transferring data to a
slot where it can be exported to a backup device and for restoring it to the application's database
or catalog after loss or failure. Please refer to the white papers on
further clarification.

Archiving methods

Two methods are provided for archiving data to the directly attached tape storage device, these are
Copy and Export.
Copy retains the data cartridge on the HP D2D Backup system and creates an exact copy onto a
•
physical cartridge in the attached tape storage device.
• Export removes the data cartridge from the library on the HP D2D Backup System once data has
been successfully copied to the physical cartridge in the attached tape storage device.
Each method has advantages and disadvantages, as described in more detail below.
NOTE:
As a general recommendation, Copy is the easier of the two options to use because it does not remove
the data from the HP D2D Backup System and can be managed completely from the Web Management
Interface. Only use the Export option, if you need to free up some disk space. Export (and Import)
require additional steps in the backup application.

Cartridge copy

The backup application on the host is used to back up data to a cartridge on the library device in the
HP D2D Backup System. The Web Management Interface on the HP D2D Backup System is used to
Copy the cartridge from the HP D2D Backup System to the attached tape storage device, leaving the
data on the HP D2D Backup System so that it is available for quick restore.
