The Portuguese Tax Authority consolidates its backup environment with ETERNUS CS8000 at lower costs

"We have seen a dramatic reduction in costs by automating tape processes for mainframe and open system environments, which has made the backup environment over 60% less expensive to maintain with better SLAs."

Carlos Costa Santos IT Director Portuguese Tax Authority/ Autoridade Tributária e Aduaneira

The Portuguese Tax Authority deployed FUJITSU Storage ETERNUS CS8000 to consolidate its backup environment, improve performance and lower costs.


The Portuguese Tax and Customs Authority (Autoridade Tributária e Aduaneira – AT) is responsible for the efficient taxation of every citizen and business in Portugal. Over 9,000 employees ensure that everybody pays their fair share towards the state. More recently, the organization has been encouraging more flexible ways to manage tax affairs through secure online portals. Availability and security are critical to the authority.


The Portuguese Tax Authority was dependent on an aging mainframe backup and tape storage system that had become unresponsive and inefficient to maintain. It was also faced with new disaster recovery compliance regulations. It needed a data protection solution that could address these needs cost-effectively.


After evaluating the market, the organization quickly came to the conclusion that only Fujitsu could provide a single data protection solution that could support both its mainframe and open system environments. Together, they spent six months migrating to a new FUJITSU Storage ETERNUS CS8000 data protection platform.


  • Cut costs by more than 60% by reducing the number of physical drives from more than 20 to 8
  • Automated replication and disaster recovery to ensure optimal availability
  • Improved performance with throughput speeds of up to 90 TB/h, making the backup and recovery more efficient
  • Easily scalable in capacity and performance to accommodate future growth
