HP D2D100 Backup System - Manual (Page 84)

• Import refers to the process that returns the cartridge from the attached tape drive to the HP D2D
Backup System.
• Copy refers to the process that creates an additional copy of the cartridge on the physical tape drive.
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 http://www.hp.com/support for further
clarification.
Archiving methods
Two methods are provided for archiving data to the directly attached tape 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 drive.
• Export removes the data cartridge from the autoloader on the HP D2D Backup System once data
has been successfully copied to the physical cartridge in the attached tape drive.
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 autoloader device (or to
a standalone tape drive 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 drive, leaving the data on the HP D2D Backup System so that it is available for quick restore.
