How much Downtime and Loss of Data can you afford?

How fast can your Business be Up and Running after a Disaster?

One or the other scenarios on the previous page

might sound familiar to you.

Furthermore, additional business requirementslead to a large degree of inter-dependency and

overall complexity of IT architectures. The avail-

ability of application landscapes and their under-

lying databases are critical.

Changing global paradigms and legal require-

ments add the need of providing full Disaster

Recovery protection, including site failure pro-

tection. Only very large distances of several

hundred miles between production and backup

site provide true protection. Traditional mirroring

concepts based on storage or blocklevel come

with too much complexity, impact productive

landscape and generate tremendous costs.

Prepare for the Future!

IT systems are constantly threatened by applica-

tion downtime and loss of data. The threats are

real and come from many directions. Not all of the

threats can be avoided. The important question

is: are you ready and prepared? How fast can yoube back in business? Can you provide a Plan B

which gets you back in business within a few

minutes with no or minimum damage? If you ex-

perience a major incident, this becomes a

challenging race against time.

Scenario 1:

Faulty Software Upgrade

The current application software is expected to be upgraded

over the weekend. The subsequent tests indicate a malfunc-

tion and thus leaves a useless system. The only option to

resume operation is a time-intensive process restoring data

from tape to disk image, extending the planned maintenancewindow.

Take a deep breath: It can be so much easier.

Scenario 2:

Physical Destruction or Disaster Incident

Lightning strikes the central power supply and/or damages

the centralized IT system. Floods, severe weather, earth-

quakes or terrorist attacks interrupt the application systems

or access to the same. Data and applications need to be

restored at an off-site location a race against time.

Stay calm: You will win the race.

Scenario 3:

Accidental Deletion of Data

It happens quickly: critical data is irrevocably deleted. The

administrator drops the wrong database. Important les or

directories are deleted. Backups must be available and an

immediate and awless manual restore is necessary tokeep your business operational.

Lean back and relax: Your data is available.

Other Scenarios:

4.Malicious manipulation by own staff or hackers

5.Hardware problems

6.Server move without downtime

7.Or simply: your business dictates you to comply with

current legislation which requires a functioning risk

management. A Business Continuity Plan is necessary

to comply with SOX and other regulations.

We will make sure that you are ready in any case.

BusinessShadow is there for you.

Traditional Methods are not enough

Todays replication tools are inadequate to pro-

vide full data and application protection. Syn-

chronous or near-synchronous data replicationtools only protect against local hardware failures

(Hardware High Availability), but do not protect

against software or user errors. Stretching the

data replication tools to mirror over large dis-

tances help to cover site failures (Disaster Re-

covery), but offer low data i ntegrity and typically

a poor Return on Investment (ROI). Manual

Backup and Restore procedures provide the data

integrity but lack reasonable Recovery Point and

Recovery Time Objectives. In addition, the com-

plexity of todays application landscapes requires

in-depth know-how of the detailed system archi-

tecture to get the systems back to life.

Comprehensive High Availability

and Disaster Recovery Protection.

Many Challenges. One Solution.

Libelle creates Leeway for Availability and

Disaster Prevention

We make it easy to handle these challenges.

Read on, and learn how you can recover your

data quickly, easily and consistently when it

comes to the worst case.

Scenarios from the World

of Corporate IT

BusinessShadow

protects your data, your applications and entire

production sites. The solution reduces potential downtime and

retrieves lost data within minutes easy to use and cost-effective.

BusinessShadowmakes your

High Availability and Disaster Recovery

Architecture Safe and Sound.

05

Foresight in assessing potential threats is the basis

for your risk avoidance strategy.

BusinessShadow is the ideal software solution which

enables you to reduce the risk of data loss, minimize

application downtime, and provide amazingly fast

error recovery. BusinessShadow provides protection

independent from the cause and independent from

the consequence of the incident: hardware failure,

corrupt data, software error or human error.

BusinessShadow supports both homogeneous and

heterogeneous system landscapes with a single

standardized interface. Also the distance and network

between your production and backup system means

no boundary. Data is mirrored with minimum band-

width requirements.

Any major incident is a race against time where every

second counts. We provide a simplied way to han-

dle the administration and failover without requiring

specic in-depth know-how.

45 % Software Error

15 % Hardware Error

40 % Human Error

Reasons for Downtime

Application downtimes and data loss are less

than ever caused by hardware problems. More

than 80% of all downtime incidents are actually

caused by software or user errors instead.

These are exactly the areas where traditional

concepts will fail in providing protection.

Redundancy will be of no help in case of corruptor deleted data. In this case, resuming business

operation will require a manual restore from

tape or disk image.

This is not only annoying, but also very time-

consuming.

The Libelle Principle

Brilliantly Simplied

Simply Brilliant.

The Time-Delayed Data Mirror!

Take an example: your application crashes at2:00 pm and critical data is irrevocably deleted.

With BusinessShadow your application and

data can be back where it was at 1:59:59 pm

literally at the push of a button and a short wait

time of typically a couple of minutes.

The time-delayed data mirror provides a manage-

able buffer between the production and its mirror

system called the time-funnel. This time-funnel

receives current transactions from the production

database or le system. The time-funnel and all

data is physically stored on the mirror system and

current transactions are available on the mirror

system in case the production system becomes

unavailable or corrupted.

In the case of a disruption, applications can

simply be switched to the mirror system. Instead

of working with the same corrupted data which

caused the downtime on the production site, onlythe good transactions are applied to the mirror

system. Typically up to the point before the data

corruption on production occurred.

And all this happens within a few minutes

without restoring backup media.

Step 1: Initial Copy

During initial setup, all data from the production

system is copied to a secondary system (mirror

system) in a LAN or WAN setting. This system can

be located in another building, another city, another

country or on another continent. Proprietary data

transmission techniques based on standard net-

work protocols optimize the data transfer.

Step 2: Updating Changes

All changes in the production system are being

identied and transferred directly into the time-

funnel of the mirror system. With the optimized

data transmission techniques, even limited WAN

links will be used to maximum efciently.

Step 3: Time-Funnel

Transactions on the production system reside in

the time-funnel on the mirror system for a certain

amount of time, which can be set to any value

desired. The time-funnel value can be adjusted

during production just as needed. Only after the

end of the dened period, the transactions in the

time-funnel are applied to the mirror system.

Step 4: Failover to the Mirror System

In the case of an error on the production system,

time can literally be turned back to any time-stamp

prior to the occurrence of the error. Within a few

minutes, in which the time-funnel is emptied to the

desired point-in-time, the last consistent set of data

is used for running production on the mirror system.

The host name and IP-address are automatically

failing over to the mirror system, so that application

server and users are able to reconnect to the mirror

system without any changes.

Step 5: Failback to the Production System

The crashed production system is rebuilt while

production is running on the former mirror system

(which is now acting as the current production).

Normal operation is reestablished by changing

roles at the push of a button.

DBShadow

BusinessShadow is the integrated Libelle solution for complete

protection of systems (databases, le systems, communication)

and combines three unique components in a holistic way.

DBShadowfor Database Protection

The easiest way to create and manage a shadow database is

offered by Libelle with DBShadow, a product that protects

against the consequences of physical and user/software errors.

The creation of the database mirror, the shipping of archive les,

and the time-delayed recovery are automated by DBShadow.

The mirror operation can be monitored either through a Graphical

User Interface (GUI) or a Command Line Interface (CLI) with user

exits. It is a perfect t to be integrated with existing High Availa-

bility concepts and strategies. Production and mirror system, as

well as all processes are monitoring each other constantly.

Trouble tickets are issued automatically for system monitoring.

FSShadowfor File System Protection

Software/User Errors and physical problems are not only a threat

to the availability of databases, but also threaten the availability of

le systems.

The same way DBShadow protects databases; FSShadow

mirrors transactions time-delayed on a at le level (create, modi-

fy, and delete). All changes are copied instantly to the mirror

system, but stay in the time-funnel before they are applied to the

actual mirror le system.

SwitchApplicationfor Automation of Failover

SwitchApplication adds an additional virtual IP-address/hostname

to the production system. Part of the failover process is to acti-

vate the virtual IP-address/hostname on the mirror system and

remove them on the production system. DBShadow and

FSShadow are continuing the mirror operation and manage the

failover using the actual IP-addresses/host-names of the produc-

tion and of the mirror system. The system can thus always be

accessed with the same IP-address.

The failback is done the same way. The automatic restart of ap-

plications are implemented through user interfaces which offer

event-based triggers to automate environment-specic actions.
