2.9 Path to tape (PTT)
The OST presentation requires the Symantec NetBackup (7.1.x or later) or Backup Exec
2010 R3 or later host application and the OST Plug-in client installation on the media
server.
Windows 2012 64-bit requires Symantec NetBackup (7.6 or later) or Backup Exec
2014 or later.
Plug-in clients are host-OS dependent and are supplied by Fujitsu Technology Solutions. To
use the ETERNUS CS800 in OST mode, you must configure an OST storage server and LSUs
on the ETERNUS CS800. You must also map the LSUs on the NetBackup server so that
NetBackup can perform backups and restore from them. Additionally, policies for
optimized duplication (OST replication) and OST direct to tape may need to be set on the
NetBackup server.

2.9 Path to tape (PTT)
The path to tape (PTT) capability allows writing data stored in the ETERNUS CS800 to a
tape library which is attached to an FC port of the ETERNUS CS800 system. With path to
tape, backup data can be moved directly from the ETERNUS CS800 system to a tape library
without the need to travel through a backup host. A common use case for PTT is to create
removable media for long term storage. Path to tape is available on all ETERNUS CS800
models with FC port option. PTT is supported by a number of backup applications
including:
l Symantec™ NetBackup™
l Symantec™ Backup Exec
l Oracle® Secure Backup
ETERNUS CS800 36
