One of the biggest advantages of virtual tape
over real tape is that it can bring a quick ROI,
which is a good thing when it comes to
managing your data center expenses.
problem. Organizations are adopting business continuity and recovery strategies by utilizing various
storage technologies to address
operational risks.
The use of virtual tape storage allows businesses to benefit
from virtualization of physical
tape and achieve their goals of
solid, long-term data retention at
a lower cost. Various virtual tape
storage configurations provide
high availability and rapid disaster recovery (DR). Another plus is
the ability to perform end-to-end
data encryption for security and
to meet regulatory guidelines.
With virtual tape, data can
be electronically transmitted to
a DR site and replicated, creating
a very smooth DR process. Data
can be selected to push certain
types of data out to the DR site
because only specific portions of
tape need to be replicated to the
DR environment.

Creating a Virtual
Tape Strategy
Choosing the correct strategy for
virtual tape isn't always obvious.
With shrinking backup windows,
poor reliability of backup systems,
performance issues or escalating
costs, selecting a new strategy can
be daunting. When looking at data
protection strategies, virtual tape is
on the continuum from conventional tape, continuous data protection
and asynchronous/synchronous
replication to three node disaster
recovery. Most strategies will rely

archiving solution.

When considering a strategy for
virtual tape, ask yourself the following questions:
*
*
*
*
*
*

What is the projected budget?
Who will support the solution?
What is the timing of the
backup window?
How can existing investments
in virtual tape be utilized?
How much data loss is
acceptable?
What is the ROI?

Knowing the answers to these
questions will help you formulate an
acceptable virtual tape strategy. All
$Ä®ÇÄ&! %Ã!Ã'&  Ã&ÉÃ&ÉÇnology must be fully understood-
including topics such as, "How
will deduplication and encryption
impact recovery times?" and "How
will compliance affect the virtual
tape strategy?" Think about how to
keep the auditors happy.

How to Measure Virtual
Tape Performance
When discussing the metrics of
virtual tape, it helps to think about
DASD measurements. The use of
SMF and RMF records can yield a
lot of information on exactly how
well your virtual tape is performing. The measurements for virtual
tape mirror DASD measurements
in quite a few ways. The virtual tape
is really just the tape format written
to disk so a lot of the DASD metrics
do indeed apply.
To make your virtual tape work
at its peak, you should always
ensure that your host processes are
working well and your interfaces

When Modernizing,
Don't Forget About
Operations
Are you still using physical tape to
back up your systems? If so, think
about this. Many articles have been
written about modernizing your
applications. That's a good plan, as
it will improve user interfaces and
generally makes the application
more supportable. Modernization
does not stop at applications. One
area of operations to review is your
backup environment.
So why use a virtual tape library
(VTL) as part of your operations modernization? Try these "S"s on for size.
* Simplicity. Your IBM i system
already knows how to use tape. It's
a simple upgrade with little or no
operational changes.
* Security. No tapes are lost or
damaged when transporting offsite. VTLs can send a copy of the
tape to a remote location over the
network.
* Safety. Tape backup is point-intime, meaning they can recover
from disk corruption and operational errors among others.
* Space and environment. VTLs
take up less space than a room
full of tapes. VTLs will also generally
consume less power than a physical tape library.
* Service. VTL processes can be
fully automated from backup processing to offsite replication.
* Speed. There's no need to go
hunting for the right tape. It will be
there online for you.
