World market leader in the field of tape libraries.

Our solutions in the area of storage automation
For more than 30 years, a wide variety of global players in the field of data backup and archiving systems have relied on our products and solutions. As the world market leader in the field of data backup and archiving systems based on LTO tapes, we have a market share of around 70%. With our many years of experience and innovative strength
we provide our OEM partners with reliable and efficient products for the secure long-term archiving of large volumes of data.
The trend towards archiving is driving our business forward
The amount of digital data worldwide more than doubles every two years. Legal requirements around the world dictate that data must be stored for longer and longer periods of time. Pharmaceutical companies in the USA, for example, are obliged to store their data for up to 100 years. Banks and insurance companies are required to archive data for 15 to 30 years.
