Press Release Summary = With these components any software or hardware company can
enhance its storage, replication and WAN communication products, by providing them
with the most advanced Byte-level Delta Deduplication Technology.

Press Release Body = Bilbao, Spain, December 18, 2006 - Lortu Software S.L., a
leading provider of Byte-level Delta Deduplication Technology, announced today the
public release of new components based on Kondar technology for implementing
Deduplication, replication, WAFS and WAN Optimization products.

Deduplication (sometimes called Single-Instance Storage, Capacity Optimization or
Factoring) is a data reduction technology intended to eliminate redundant
(duplicate) data on a storage system by saving only one instance of each piece of
data in order to reduce disk space and network bandwidth.

The are several types of deduplication technologies:
- File deduplication. Only one copy of each identical file is stored. This
technology is also known as Single File Instance technology.
- Data compression. Sometimes data compression is included as a deduplication
technology, however data deduplication differs from compression in that compression
looks only for repeating patterns of information and reduces them. On the other
hand, data deduplication results in reducing the unique data regardless its internal
format. The typical reduction ratio of compression is x2 and the reduction ratio of
byte level deduplication is x50.
- Block level deduplication. Divides the information in blocks and only one copy of
each identical block is stored.
- Byte level deduplication. Analyzes the content of the information to be
deduplicated at byte level and only stores the really unique data. This is the only
technology that guarantees full elimination of redundant data.

This means that different deduplication technologies can also provide different
granular control, removing redundant portions of files, potentially down to the
block level or even to the byte level.

When evaluating a deduplication product, it\'s important to understand the
granularity offered by their platform.

Kondar deduplication technology.
Basically Kondar deduplication technology is able to compare two blocks of data and
find the differences between them at byte level. The main feature of Kondar is that
it's able to do this deduplication process with very large blocks of data, at byte
level and very fast.

Kondar is data-format independent and can work with any kind of data: files, memory
buffers, disk images or data in streaming mode.

Here are just some examples to demonstrate the power and flexibility of Kondar
deduplication technology:
- Kondar can receive a stream with new data, compare it with other previously stored
data and create an output stream containing the data which is unique in the new
stream. All of this is done at byte-level. This approach is also known as
delta-based caching deduplication.
- Kondar can also work in a client/server architecture where it compares a new
version of a file or piece of data to be deduplicated (on the client) with the
initial version of that file (on the server), transferring only a minimal amount of
information to create a patch file on the server with the differences. This approach
is very useful for data replication products.
- Another variant of this approach is to store on the client a small file small file
instantiating the initial version of a file or piece of data to be deduplicated and
do the comparison without having the initial file cached locally. Then the small
patch file with the differences can be sent to a remote location.
- Kondar can provide a Lortu proprietary file system API to create a data vault.
Your products can send any kind of file to the Kondar component and Kondar will
apply single-file instance and byte-level deduplication technology comparing all new
files with all information stored so far in the vault. This approach guarantees that
the vault holds only unique chunks of data.

Thanks to its byte level deduplication algorithms, Kondar can be used to achieve a
data reduction ratio of between 10 and 100 times.

"Based on our philosophy of developing software components to be integrated into
third party companies' software or hardware products, Kondar is not a final product
or a closed component." said Carlos Ardanza, CEO of Lortu Software. "Instead, Kondar
is a technology that can provide the API that best suits our clients\' products. Even
more, we can fine-tune our technology in order to get the best performance and
easiest integration with your products."


Implementing WAN optimization and WAFS controllers with Kondar technology.

WAN optimization and WAFS controllers can benefit from Kondar technology because
Kondar can provide deduplication capabilities from data streams.

The process could be as follows:
1- Kondar receives a stream with new data (incoming stream) from the host application.
2- Kondar compares the incoming stream with the local cache previously stored.
3- Kondar creates an output stream with the differences, which is sent to the remote
controller.
4- At the remote controller Kondar is able to restore the incoming stream from the
output stream that was sent by the remote controller and the local cache.
5- Finally Kondar adds the unique data (output stream) to the local cache of the
remote controller. In this way, it won't be necessary to send this data through the
WAN connection again.

All of this would be done at byte-level. This approach is also known as delta-based
caching deduplication.

In those cases where the communication is one way, Kondar can deduplicate the stream
without storing the local cache in the first controller. Kondar just needs to store
a small file with some information about the remote controller cache in order to
compare the incoming stream with the remote cache. In this way, the local cache is
only required for the restoration process at the remote controller. This approach
involves an important HD reduction, leading to price reductions and increased
competitiveness of products using Kondar technology.

"There are many other possibilities and we will be happy to discuss the best
approach for each one of our clients' products." explains Alejandro Arostegui, Sales
Manager of Lortu Software. "For companies interested in implementing deduplication
technology in hardware, Kondar algorithms have been especially designed to be
implemented in FPGA, ASIC or proprietary multi-processor hardware where our clients
can take advantage of their parallelism and multithreading capabilities, providing a
great throughput and scalability grade."
