This data will be backed up to an autoloader configured on the HP D2D Backup System. Additionally, there is an 'IMPORTANT' folder that relates to current, high-priority projects that must be backed up daily and moved from the HP D2D to physical tape at the end of each week. This data will be backed up to a standalone tape drive configured on the HP D2D Backup System. You can specify the number of slots to meet the backup requirements for the workstation when you run the Installation wizard, or from the Web Management interface after installation. You must use the Devices page of the Web Management interface to create an additional standalone tape drive device for the 'IMPORTANT' folder. (See "To create a new device" on page 66 for further details.) Main backup to autoloader The data at 250 GB exceeds the disk space that can be allocated to a single slot. Therefore, each full backup requires two autoloader slots. You must also make sure that tape spanning is enabled in your backup application.

High-performance workstation backup
This is a high-performance graphics workstation, used by an architect, who has 250 GB of data that must
be fully backed up every week and approximately 10 GB of changes to be backed up each day. This
data will be backed up to an autoloader con
fi
gured on the HP D2D Backup System.
Additionally, there is an ‘IMPORTANT’ folder that relates to current, high-priority projects that must be
backed up daily and moved from the HP D2D to physical tape at the end of each week. This data will be
backed up to a standalone tape drive con
fi
gured on the HP D2D Backup System.
You can specify the number of slots to meet the backup requirements for the workstation when you run the
Installation wizard, or from the Web Management interface after installation. You must use the Devices
page of the Web Management interface to create an additional standalone tape drive device for the
‘IMPORTANT’ folder. (See “
To create a new device
” on page 66 for further details.)
Main backup to autoloader
The data at 250 GB exceeds the disk space that can be allocated to a single slot. Therefore, each
full backup requires two autoloader slots. You must also make sure that tape spanning is enabled
in your backup application.

Additional backup to tape drive
The ‘IMPORTANT’ folder starts at 10 GB and has 4 incremental backups to a single cartridge on a
standalone tape drive. The
fi
nal data size is approximately 60 GB, which is moved from the HP D2D to
physical tape weekly.
