The Oracle Zero Data Loss Recovery Appliance (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. It is designed for Oracle databases and works only on Oracle databases. It is considered a 3rd party backup and recovery product. It was introduced in 2014 as part of Oracle Corporation's family of "Engineered Systems" and shares components with the
