10 Copy using a tape drive attached to the
host
In this chapter:
• “Requirements” on page 171
• “Using a tape drive connected to host” on page 172
• “Compression” on page 172
Requirements
If you wish to copy data from the HP D2D Backup System to a tape drive connected to the host
machine, you need:
• A separate tape device, such as a full-height or half-height HP StorageWorks Ultrium LTO tape
drive, that can be connected directly to your host.
• A backup application, running on the host, that allows you to copy data from the cartridge on
your HP D2D Backup System to the physical cartridge.
NOTE:
It is not possible to export and import data using this method. Export and import are only supported
on tape drives that are connected directly to the HP D2D Backup System. See
“Using Tape Attach” on page 147
Tape drives supported
The HP StorageWorks Ultrium LTO–2, –3 or –4 tape drives are the ideal devices for all copying
processes because the physical cartridge sizes match the maximum configured cartridge sizes on the
HP D2D Backup System. However, by spanning across several tapes, you can also use a tape drive
with a lower capacity, such as an HP StorageWorks DAT 72 tape drive. If your backup application
will not allow you to span tapes, you may want to use the Web Management Interface to reduce the
maximum configured cartridge size on the HP D2D Backup System. However, you must do this when
you first create the library or additional slots and before you have used the library in any way with
your backup application. See “To edit maximum cartridge size” on page 119.
NOTE:
Always refer to http://www.hp.com/go/connect or http://www.hp.com/go/ebs to find out which
tape drive models are recommended.
