The Oracle Zero Data Loss Recovery Appliance{{Cite web|url=http://www.oracle.com/technetwork/database/availability/recovery-appliance-ds-2297776.pdf|title=Oracle Zero Data Loss Recovery Appliance X7 Technical Data Sheet|last=Various authors|date=2017|website=Oracle Corporation|access-date=July 30, 2018}} (Recovery Appliance or ZDLRA) is a computing platform that includes Oracle Corporation (Oracle) Engineered Systems hardware and software built for backup and recovery of the Oracle Database. It performs continuous data protection, validates backups, automatically resolves many issues, and provides alerts when backups fail validation.{{Cite web|url=https://horison.com/publications/implementing-a-modern-backup-architecture|title=White Paper: Implementing a Modern Backup Architecture: Oracle's Tiered Data Protection Strategy|last=Moore|first=Fred|date=June 1, 2015|website=Horison.com|access-date=July 30, 2018}}{{Cite web|url=http://www.oracle.com/us/products/oracle-zdlra-final1-2301371.pdf?source=%3Aow%3Alp%3Acpo%3A%3A|title=CIO Magazine White Paper: Extreme Protection That Eliminates Data Loss for All of Your Oracle Databases|website=Oracle Corporation|access-date=July 30, 2018}}{{Cite web|url=http://medianetwork.oracle.com/video/player/5070016766001|title=Video: Resume Business Faster With Engineered Database Recovery|website=Oracle Corporation|access-date=July 30, 2018}}

It is designed for Oracle databases and works only on Oracle databases. It is considered a 3rd party backup and recovery product.{{Cite web|url=https://wikibon.com/oracle-backup-and-recovery-strategies-moving-to-data-protection-as-a-service/|title=Oracle Backup and Recovery Strategies: Moving to Data-Protection-as-a-Service|last=Vellante|first=David|date=October 22, 2015|website=Wikibon|access-date=July 30, 2018}}{{Cite web|url=https://wikibon.com/real-time-recovery-architecture-as-a-service/|title=Real-time Recovery Architecture as a Service|last=Floyer|first=David|date=September 2, 2016|website=Wikibon|access-date=July 30, 2018}}{{Cite web|url=http://www.oracle.com/us/corporate/analystreports/idc-zero-data-loss-rec-app-3350796.pdf|title=Oracle's Zero Data Loss Recovery Appliance: A Transaction DVR for the Enterprise|last=Goodwin|first=Phil|date=November 1, 2016|website=IDC (International Data Corp)|access-date=July 30, 2018}}{{Cite web|url=http://www.oracle.com/us/products/engineered-systems/tg-recovery-app-lights-year-ahead-2842666.pdf?source=%3Aow%3Alp%3Acpo%3A%3A|title=Taneja Group Whitepaper: FULL DATABASE PROTECTION WITHOUT THE FULL BACKUP PAIN|website=Taneja Group|access-date=July 30, 2018}}

It was introduced in 2014 as part of Oracle Corporation's family of "Engineered Systems"{{Cite web|url=http://chucksblog.typepad.com/chucks_blog/2015/09/grown-up-it-for-grown-up-applications.html|title=Chuck's Blog: Grown-up IT for Grown-Up Applications|last=Hollis|first=Chuck|date=September 9, 2015|website=typepad|access-date=July 30, 2018}} and shares components with the Oracle Exadata Database Machine, with an additional layer of software that provides specific features for backup, recovery, replication, monitoring, and management. Like the Oracle Exadata Database Machine, it is periodically refreshed as a new interoperable and expandable “generation” based on newer hardware technology at the time of release. In September 2019, the Recovery Appliance X8M introduced a 100 Gbit/s internal network fabric based on RoCE (RDMA over Converged Ethernet), replacing the InfiniBand fabric used in previous Recovery Appliance generations.

The Recovery Appliance elastic configuration starts with a "Base Rack" that can be increased to a "Full Rack" or larger "multi-rack" configuration. A Base Rack is capable of managing over 207 terabytes of backup data, while a Full Rack can manage over 1.26 petabytes. Multi-Rack configurations of up to 18 racks wide can manage more than 22 petabytes of data.{{Cite web|title=Announcing Zero Data Loss Recovery Appliance X9M: Database Transaction-level Protection – Now with Greater Capacity at Half the Price|url=https://blogs.oracle.com/maa/post/zdlra-x9m}} Since Recovery Appliance only needs to store data that has changed, the actual size of databases that are protected can be many times larger than the storage capacity of a Recovery Appliance.{{Cite web|url=https://chriscraftoracle.wordpress.com/2018/02/21/de-duplication-in-zdlra/|title=De-Duplication in ZDLRA|last=Craft|first=Chris|date=February 21, 2018|website=Wordpress|access-date=July 30, 2018}}
