Data storage in cloud computing centres is gaining popularity for personal and institutional data backups as well as for highly scalable access from software applications running on attached compute servers. The data is usually access-protected, encrypted and replicated depending on the security and scalability needs. Despite the advances in technology, the practical usefulness and longevity of so-called cloud storage is limited in today's systems which severely impacts the acceptance and adoption rates. Therefore, we introduce a novel cloud storage management architecture which combines storage resources from multiple providers so that redundancy, security and other non-functional properties can be adjusted adequately to the needs of the user. Furthermore, we present NubiSave, a user-friendly implementation with configurable adequate overhead which runs on and integrates into contemporary desktop systems. Finally, a brief analysis of measurements performed by us shows how well the system performs in a real distributed cloud storage environment.
