the number of slots during installation.

Import/Export and Copy
If you a t tach a supported, physical tape drive directly to your HP D2D Backup System, you will be
able to copy o r 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 B ackup System; exported data is removed from it, but ca n
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 tha t the HP D2D B ackup System plugs directly
into t
he 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 d escribed 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 s lot that is used specifically to
import and export car tridges. They are sometimes ca lled 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 car tridges in the mail slot when the user runs an Import job.
