Oracle Reinvents Database Protection with Zero Data Loss Recovery Appliance
During his opening keynote at Oracle OpenWorld 2014, Oracle Executive Chairman and Chief Technology Officer Larry Ellison announced the general availability of Oracle’s Zero Data Loss Recovery Appliance, the world's first and only engineered system designed specifically for database protection. This massively scalable appliance delivers unparalleled data protection, efficiency, and scalability.
Current backup and recovery solutions treat databases simply as files to copy rather than as transactional systems with specific data integrity, performance, and availability requirements. With these solutions, businesses typically lose all data generated since the last backup—often resulting in the loss of hours or days of critical data.
“Our new data protection strategy eliminates a decades-long paradigm that is simply unacceptable for meeting enterprise needs,” says Vice President of Product Management for Oracle Database high-availability technologies Ashish Ray. “It’s really unthinkable that businesses still regularly lose volumes of critical database transactions between backups. That is one of the fundamental problems we have solved with Zero Data Loss Recovery Appliance.”
Zero Data Loss Recovery Appliance scales to protect thousands of Oracle Databases across the entire data center and can ensure that any of those databases can be recovered to any point in time—even to the very last subsecond before an outage. And because it performs lightweight incremental backups, it has a negligible performance impact on production environments and does away with disruptive backup windows.
Zero-to-Subsecond Data Loss Protection
Many innovations help Zero Data Loss Recovery Appliance ensure zero data loss, but most critical is the real-time redo transport feature. These redo blocks are the fundamental units of transactional changes within the database. The appliance makes it possible for databases to continuously send these redo blocks in real time directly from memory to the appliance. By capturing these redo blocks and incremental backups, Zero Data Loss Recovery Appliance can create a virtual full backup that enables a database to be restored to any point in time.
Other key data protection innovations include
- End-to-end data validation. Because Zero Data Loss Recovery Appliance is programmed with an understanding of internal Oracle Database block formats, it supports deep levels of end-to-end data validation—from data creation to tape archival. This continuous validation maintains data integrity and eliminates data corruption.
- Secure replication. Backups on a local Zero Data Loss Recovery Appliance can be easily and quickly replicated via secure transport to a remote Zero Data Loss Recovery Appliance system for protection against a site outage or disaster.
- Autonomous tape archival. The appliance automates full or incremental database backups directly to tape storage for long-term retention and archival purposes—offloading production database servers. Archival operations can also run both day and night to improve tape drive utilization.
Minimal Performance Impact and Higher Efficiencies
Zero Data Loss Recovery Appliance offloads all expensive backup operations from production systems, so database server performance remains unaffected. In addition, incremental forever backups eliminate unproductive backup windows that hamper business operations. Two key innovations help the appliance reduce performance impact to near zero and boost storage efficiency.
- Delta push. Protected databases simply send Oracle Recovery Manager incremental backups to the appliance. Because only changed data is backed up, there’s no longer a need for periodic full backups to disk or tape storage.
- Delta store. On the Zero Data Loss Recovery Appliance side, the delta store validates incoming data blocks and then compresses, indexes, and stores them. These blocks are the foundation of virtual full database backups, which are essentially space-efficient, pointer-based representations that enable long backup histories to be kept online with maximum storage efficiency.
Enabling Cloud-Scale Protection
Zero Data Loss Recovery Appliance provides the massive scalability to expand to many petabytes of storage and support thousands of databases with a single system, enabling organizations to deliver centralized database protection as a service. Administrators can also easily scale storage, server, and networking resources without downtime to support continued data growth and the dynamic needs of multiple business units across an organization.
Companies can now consolidate backup islands and move to a much more efficient shared-services model.
Simplified Management
For IT staff, this shift from full backups to continuous real-time data protection eliminates hours of tedious work each week (or weekend). In addition, most data protection tasks, including standardizing protection requirements for new database deployments, can be fully automated with simplified policy-based management. This means IT can focus on the other tasks on its to-do list—such as helping the company innovate and save money.
Rather than relying on multiple management tools to support data protection operations across the enterprise, administrators can leverage Oracle Enterprise Manager Cloud Control to gain end-to-end visibility and control of the entire database protection lifecycle—from data creation to disk backup to tape archival—via a single console.
Now, for the first time, organizations can meet all their critical database protection needs, including real-time protection, end-to-end recovery, and centralized control for thousands of databases, with a single system.
