1. Overview
1.1 Software Overview
XenData6 Workstation software provides high performance archiving to and restoring from LTO data tape
using Windows Explorer. It supports one or more LTO tape drives attached to a Window 7 computer and
manages an unlimited number of offline LTO tapes. Additionally, the software allows creation of reports for
management of the archive, including the ability to list the contents of any tape, the ability to search for files
and the generation of an archive status report.
Archive and restore operations are always performed using Windows Explorer. XenData6 extends
Windows Explorer's capabilities to transfer files to and from LTO using drag and drop or copy and paste.
Files may be archived to LTO from any accessible logical drive letter or network share. Similarly, files may
be restored to any accessible drive letter or share. The system maintains file and folder structures, allowing
the transfer of nested folders to and from LTO tape.
Archive and restore operations are described in Archiving Files to LTO (3.1) and Restoring Files from LTO
(3.2). XenData6 Workstation gives an option to copy to LTO only files that have changed or are new. This
is an easy way to create an updated copy of project folders on LTO.
XenData6 Workstation can manage a large offline LTO tape archive as the files and folder structure stored
on all tapes that have ever been inserted into the LTO tape drive (or drives) may be retained. The archive
system will allow browsing of all the offline tapes that are retained 'on the shelf'. This is described further in
About LTO Shelf (4.4). A file search report can generate a list of files that meet file search criteria specified
by the user and will identify the tapes that contain each match.

XenData6 Workstation software writes to LTO tape using the open standard POSIX tar format. This is
important for long term archives because it means that files can be restored for decades to come using a
wide range of native Linux and Unix operating systems, Microsoft Services for Unix, as well as XenData
software. Tapes written with XenData6 Workstation software are interchangeable with server-based
systems running XenData6 Server software. Additional capabilities provided by XenData6 Workstation
software include the following.
All file types are supported. This includes non-video files.
Both rewritable and non-erasable WORM LTO tape cartridges are supported. For more information, see
About LTO (1.2).
LTO tapes may be grouped into XenData Volume Sets. This is particularly useful when tapes are
interchanged with server-based systems running XenData software.
1.2 About LTO
Linear Tape Open (LTO) is the leading tape format and uses technology developed by HP, IBM and
Quantum Corporation. The latest generation of LTO is LTO-5 which provides high storage capacity, high
speed file transfers and a long archival data life:
Huge storage capacity Each tape cartridge stores 1.5 TB without any compression. For video files, this
represents over 65 hours at a 50 Mbits/s recording rate.
High speed file transfers LTO-5 tape drives write to and read from tape at up to 140 MBytes/s.
Long archival data life LTO tape cartridges are available from multiple manufacturers that specify a 30
years archival data life.
LTO-5 tape drives are compatible with LTO-5 1500 GB, LTO-4 800 GB and LTO-3 400 GB tape cartridges.
LTO-5 and LTO-4 tapes are fully read-write compatible. Whereas LTO-3 tapes cannot be written but can be
read in LTO-5 tape drives.
9
LTO-4 tape drives are compatible with LTO-4 800 GB, LTO-3 400 GB and LTO-2 200GB tape cartridges.
LTO-4 and LTO-3 tapes are fully read-write compatible. Whereas LTO-2 tapes cannot be written but can be
read in LTO-4 tape drives.
LTO tape cartridges are available as rewritable or WORM. WORM is an acronym for Write Once Read
Many and the data written to WORM LTO tape cartridges cannot be altered. This means that WORM tapes
cannot be reformatted and reused, unlike rewritable cartridges.

1.3 Software Licensing
1.3.1 About Licensing
XenData6 Workstation is licensed under the terms of the End-User License Agreement (EULA) which
must be accepted when the software is installed. You may only use the XenData6 Workstation
software to access, read data from or write data to specific tape drives which have been assigned to
an authentic and valid license.
Under the terms of the EULA, if you have purchased one XenData6 Workstation license for use with
one tape drive, you will assign a specific tape drive to that license. Then, you may install the
XenData6 Workstation software on multiple computers and use the specific assigned tape drive on
any of those computers.
1.3.2 How to License
You will need a XenData Activation Code to be able to use XenData6 Workstation software. The
software is activated by using the XenData License Administration Utility which is displayed during
installation. It may also be launched after software installation as follows.
Click 'Start', then 'All Programs', then 'XenData'.
Click 'License Administration'.
