* IMPORTANT ANNOUNCEMENT TO PREVENT DOWNTIME
(and spend 5 minutes reading my damage report )

When we opened the Sunbelt Office in the USA five years ago, I
did not know that Tampa Bay has a certain reputation. It is 
called the "Lightning Capital" of the World. In my innocence I
assumed this referred to a hockey or football team. I was wrong 
and soon helped out of my dream.

A unique atmospheric configuration gets us sunshine 95% of the 
days in the year, but also very regular thunderstorms. During the 
season it hits pretty much at the end of almost every day. 
Statistically our area gets more lightning hits per year than 
any other place on the planet. It's tens of thousands!

Anybody buying an electrical appliance costing more than about 
twenty bucks also buys a surge protector for that TV, radio 
or computer. That is no luxury but a must. I was once again 
confronted with this phenomenon last weekend. On a particularly 
dark Saturday night the sky was crackling with lightning and it 
was thundering right above our heads. We experienced at least 8 
brownouts in 30 minutes. I was wondering what the damage in the 
office would be.

One of our Techs went in on Sunday and found the following: 
- Two ports on our brand new 100Mb switch were dead
- 3 NIC's fried
- The network was down
- One board in our voice mail system burned out
- One 8-port hub in a suite down the hall was fried

And all that despite the fact we religiously protect all our 
machines as good as we can. We had spares for almost everything 
(except the switch) and after four hours of work on Sunday every-
thing was back up again. But what if the storm would have hit 
on Tuesday morning 10am? I'm sure you understand where I'm 
getting at: DOWNTIME.

In a small office like ours with about 35 computers and 25 staff 
we calculated the downtime cost. It's a thousand bucks -per hour- 
when Sunbelt USA sits on its hands waiting for the network or 
server to come back up. And that is peanuts really. Mission 
critical (web) servers can cost thousands -per minute- if they 
are down.

So, you need to protect the "Crown Jewels" of your company and 
guarantee your users access to that data. The costs of this is 
relatively unimportant. You_cannot_afford_NOT_to_do_it. The 
tool you choose to prevent downtime has to be the most reliable 
and efficient. That is -really- the priority. 

I sent you this NewsFlash because there is a new version of a 
tool that we think is the best in the market to do just that.
This product is called Double-Take and the new V3.0 features are 
making it the industry leader with I think a year's advantage 
over any other tool out there.

For new subscribers: Sunbelt has no vested interests in any 
particular product. We can basically sell what we want. So what 
we do is pick the "Best of Breed" tools in each category so that 
you can integrate those in your environment. 

So, what is special about the new V3.0 of Double-Take? The developers 
have been in this business for quite a while, first for Novell and 
since '96 for NT as well. Double-Take is used by the three leading 
disaster recovery companies in the world. They implement Double-Take 
on the systems of their customers to get data off site to protect it. 

NEW: MULTI PLATFORM

Early 1998 the developers took a hard look at the market and found 
what was needed and wanted in the future. You told them that you 
needed a whole slew of features, and that you also needed it 
multi-platform. The code at that time was not really ready for that. 
They decided to bite the bullet and rewrite a good chunk apart from 
the patented algorithms that had proved to work great.

Having seen most of these tools, I can tell you that Double-Take 
V3.0 is everything you ever wanted in a Fault Tolerance utility. 
They really did a great job providing the features and flexibility, 
combined with an excellent and efficient architecture. It is a great 
solution that allows you to get data from one machine to one or more 
other systems and fail over when your source machine dies for whatever 
reason. You can now mirror data from NT to Solaris and back. Netware
soon to follow. One console for all platforms, nice & easy. It combines
great with Convoy Cluster Software too.

NOTE: From my perspective Double-Take is the NEW MARKET LEADER.

HIGHLY EFFICIENT ARCHITECTURE

Let me give you a simple example why I think Double-Take has solved the 
problem smarter than some others. For instance the data that goes from 
one server to another can be handled in different ways. On the source 
side, Double-Take filters data before it goes to disk, sends it over 
the wire and writes it on the disk of the target machine just a tiny 
bit later than data gets written to the disk of your source machine.

Data gets only written once on the source and once on the target in 
the Double-Take scenario. Now, let's look how for instance Octopus 
does it: On the source, data gets written to the file, but also to 
a log file on the source. Then the data gets transported over the 
wire, and written to a log file on the target. 

From that log file on the target it gets written to the mirror-file. 
Result? Data gets written 4 times costing twice as many resources. You 
want to keep those resources available for your users on mission 
critical servers.

There are crucial differences in the architecture of these products. 
We have created a detailed grid with a competitive analysis and I 
suggest you study that carefully. Print it out in landscape and spend 
10 minutes comparing the features. You will see why Double-Take V3.0 
is technically the most advanced product: High efficiency, requiring 
the least resources. Here is the grid, but there is more!

FREE RESOURCE PLANNING TOOL

One more highly interesting technical breakthrough you will get with 
this new version is the free Resource Planning Tool. It will allow 
you to install Double-Take (without a second server!) and actually 
SEE how much bandwidth you are going to need to get data off that 
machine. Very useful to say the least.

Replication can occur in the following configurations:
- One-to-One, Active/Standby (the target does nothing)
- One-to-One, Active/Active (the target is also source)
- Many-to-One
- One-to-Many
- Chained (A to B to C)
- Single Machine (replicate data c:\ to d:\)

HIGHLIGHT OF THE FEATURES

- Strong scripting features with Double-Take Control Language
- Full Function Command line and Text Client Interfaces
- Replication from Solaris to NT and back (Novell later '99)
- Connection Wizard that makes life -very- easy
- Detailed Statistics about the process
- You can backup open files on the target machine
- Support for Microsoft Cluster Server
- Multi-NIC support
- Throttle the load on your LAN or WAN
- Supports DES encryption
- Supports NT Event Logs and SNMP
- Drag and Drop configurations and fail-over
- And there is much, much more.

You will find an excellent White Paper with the 'Theory Of 
Operations', and a new Double-Take V3.0 PowerPoint presentation at 
this page: http://www.sunbelt-software.com/dtake.htm

That's also the place where you can download the 30-day eval.
Keep in mind, it's only a matter of time before some disaster 
strikes. When it does, will you be sufficiently protected?

An abbreviated copy of the Press Release that went out this week 
with more specifics. Read the 'Additional Benefits Section'!


"AWARD WINNING SERVER REPLICATION SOFTWARE NOW COVERS UNIX"

HOBOKEN, N.J., Jan. 18 /PRNewswire/ -- NSI Software announced today 
version 3.0 of Double-Take, the company's award-winning server 
replication and server failover software. In line with NSI Software's 
strategy for embracing the burgeoning SAN/NAS market, a key feature 
of the new version is cross-platform replication. 

This initial multi-platform, cross-platform release of Double-Take 
will include Microsoft Windows NT (MSFT) and SUN Solaris (SUN) 
servers. High-Availability through system level monitoring and 
failover from NT-to-NT and Solaris-to-Solaris is also a primary 
feature of the software. 

"Customers have asked for a flexible, centralized, easy to manage 
server/data replication package -- with Double-Take 3.0 we have 
delivered that package and raised the bar on new features," Said John 
New, vice president of marketing for NSI Software. "The ease of 
centralized management, the ability to host native data from any 
supported NOS (Network Operating System) on any other NOS is truly 
remarkable, and will go a long way toward helping customers 
consolidate and optimize their data protection and disaster 
recovery plans."

DATA REPLICATION FEATURES IN DOUBLE-TAKE 3.0

Double-Take's patented real-time data replication provides the following
capabilities on top of the previous generation's award winning feature 
set:

-- Cross Platform Storage Management with Unified Management Console GUI,
or optionally;
-- Integrated, Multi-OS scripting language and full command line control
of all features;
-- Industry leading security with multi-level administration and
on-the-wire encryption of data;
-- Ability for Windows NT, UNIX and (soon) NetWare servers to "host"
non-native data from other NOS file systems, completely preserving all
file attributes Fault Tolerance Features in Double-Take 3.0

When Double-Take's replication features are used among like operating
systems, the software provides the following high availability and 
failover capabilities:

-- Disaster recovery for stand alone (Solaris & NT) or MSCS clustered NT
servers;
-- Selective data replication and failover allows selection of data to be
protected by volume, directory or even individual files;
-- One-to-many server replication (One target machine can host many failed
machines, good for disaster recovery -- if a site goes down with
multiple servers, the target, off site machine can immediately stand in
for the failed machines.);
-- Open file replication support insures that large open files --
typically databases and e-mail applications -- recover with all data
intact and with users able to access the applications and data as
before failure.

ADDITIONAL BENEFITS USING DOUBLE-TAKE

+ Double-Take can be used to consolidate tape backup operations: 
By using Double-Take to "host" data from many production file 
seRvers, the target server can then serve as an "offline," continuous 
backup station.

+ Loosely coupled server-to-server communications over existing network,
whether Ethernet, Token Ring, etc. Source and Target servers have 
bandwidth control, automatic bandwidth throttling by user-defined 
thresholds, and efficient use of existing available bandwidth to insure 
the most effective and efficient processing of data possible. There is
replication scheduling that will trigger either based on time (e.g.
every night at 9pm connect and sync) or based on replicated data size 
(e.g. when XX megabytes are queued, make the connection and sync).

+ WAN-efficient operation makes disaster recovery and off site hosting 
of live data economical, reliable, and with new on the wire encryption
-- secure.

+ Using cross-platform replication eases storage management, backup
management and disaster recovery by providing one intuitive interface, 
whether you choose graphical, text based, command line or scripted.

+ Additional versions of UNIX will be added throughout 1999, with 
priorities given to the most popular, widespread versions within NSI's 
current customer base. Those customers include third-party developer 
and OEM arrangements with IBM and IBM Business Recovery Services, 
Hewlett-Packard, SunGard, Dell Computer Systems and Compaq Computer, 
among others. AIX, HP-UX and SCO are likely next versions available 
to customers.

+ Novell (NOVL) NetWare will be added to the cross-platform implemen-
tation by Q2 1999 -- but in the meantime, Double-Take version 2.6 
offers a superb NetWare-to-NetWare server replication and server 
failover solution. NSI Software is committed to providing continued 
support for NetWare.

+ VERIFICATION. Everybody knows that doing a backup is useless unless
you can do a restore when you really need to. But who has time to
actually test that? With DT V3, there is a verification function that
may be scheduled as you wish. If a discrepancy is found, the Double-
Take can be told to either report the problem or report and fix the out
of sync data. This way you are regularly assured that the data on your
source machine matches that of your target machine. Very cool...

PRICING AND AVAILABILITY

Double-Take 3.0 for Windows NT and Solaris is available now through 
all authorized NSI Software resellers and distributors. Introductory 
pricing starts at $1,495 per server. 

ABOUT DOUBLE-TAKE

Double-Take(R) is the first multi-platform and cross-platform real-
time data protection product for Windows NT, Unix and NetWare. Working 
in real time at the operating system level, Double-Take replicates 
selected data or complete file systems from one or more source servers 
to one or more target servers across existing LAN or wide area links. 

This patented technology is used to provide high availability for 
network servers, to centralize tape backup or to provide offsite 
disaster recovery.

High availability solutions involve an advanced set of recovery 
techniques that reduce recovery time and eliminate or decrease the 
amount of information lost in a disaster or disruption. As businesses 
increasingly depend upon the availability of information, business 
recovery companies are developing offerings for this new approach. 

These techniques, which involve electronic transfer, may be used in 
lieu of conventional recovery plans for critical backup data. They 
shorten the recovery window by eliminating the need for physical 
transport of information, which may take 24 to 48 hours.
