The HP D2D Backup System can be used to back up a maximum of six hosts 2. The Installation wizard automatically generates an autoloader for each host. The user may specify the number of slots during installation. Figure 3 Device configuration with multiple hosts Import/Export and Copy If you attach a supported, physical tape drive directly to your HP D2D Backup System, you will be able to copy or export data to the physical tape drive so that backups can be stored offsite. This is an important requirement for Disaster Recovery strategies. The main difference between copy and export is that copied data remains on the HP D2D Backup System; exported data is removed from it, but can be imported easily when required. These functions are grouped under the Tape Attach section of the Web Interface. Please see "Export, import and copy to an attached tape drive" on page 83 for more details about working with Tape Attach. iSCSI The HP D2D Backup System is an iSCSI device. This means that the HP D2D Backup System plugs directly into the network, but it presents devices as directly-attached SCSI autoloaders to host machines. In order to function, it requires an iSCSI initiator. On Windows systems, this is normally downloaded by the Installation wizard, as described in "Connecting and installing the HP D2D Backup System" on page 23. For more information about iSCSI, see "Advanced installation" on page 45. Linux users should also refer to the "Linux Configuration Guide" on the HP StorageWorks Tape CD-ROM for more information. Mail slots (import/export elements) A mail slot is a term borrowed from tape terminology to identify a dedicated slot that is used specifically to import and export cartridges. They are sometimes called import/export elements by backup applications. Backup applications that support this feature move cartridges from the mail slot when the user runs an Export job, and look for cartridges in the mail slot when the user runs an Import job. 18 Before you start

Import/Export and Copy
If you attach a supported, physical tape drive directly to your HP D2D Backup System, you will be
able to copy or export data to the physical tape drive so that backups can be stored offsite. This is an
important requirement for Disaster Recovery strategies. The main difference between copy and export
is that copied data remains on the HP D2D Backup System; exported data is removed from it, but can
be imported easily when required. These functions are grouped under the Tape Attach section of the
Web Interface. Please see “

” on page 83 for more
details about working with Tape Attach.
iSCSI
The HP D2D Backup System is an iSCSI device. This means that the HP D2D Backup System plugs directly
into the network, but it presents devices as directly-attached SCSI autoloaders to host machines. In order
to function, it requires an iSCSI initiator. On Windows systems, this is normally downloaded by the
Installation wizard, as described in “
Connecting and installing the HP D2D Backup System
” on page 23.
For more information about iSCSI, see “

guration Guide” on the HP StorageWorks Tape CD-ROM for more information.
Mail slots (import/export elements)
A mail slot is a term borrowed from tape terminology to identify a dedicated slot that is used speci
fi
cally to
import and export cartridges. They are sometimes called import/export elements by backup applications.
Backup applications that support this feature move cartridges from the mail slot when the user runs an
Export job, and look for cartridges in the mail slot when the user runs an Import job.
