Oracle's Recovery Appliance Solution
Recovery Appliance is a cloud-scale Engineered System designed to protect all Oracle databases across the enterprise. Most database backup and restore processing is performed by the centralized Recovery Appliance, making storage utilization, performance, and manageability of backups more efficient.
The Recovery Appliance stores and manages backups of multiple Oracle databases in a unified disk pool, using an RMAN incremental-forever strategy. The Recovery Appliance continually compresses, deduplicates, and validates backups at the database block level, while creating virtual full backups on demand.
A virtual full backup is a complete database image as of one distinct point in time, maintained efficiently through Recovery Appliance indexing of incremental backups from protected databases. A virtual full backup can correspond to any incremental backup that was received.
Figure 1-5 shows an overview of a sample Recovery Appliance environment.
As shown in Figure 1-5, a protected database is a client database that backs up data to a Recovery Appliance. Each protected database uses the Zero Data Loss Recovery Appliance Backup Module (Recovery Appliance Backup Module) for its backups. This module is an Oracle-supplied SBT library that RMAN uses to transfer backup data over the network to the Recovery Appliance.
The Recovery Appliance metadata database, which resides on each Recovery Appliance, manages metadata stored in the RMAN recovery catalog, and backups located in the Recovery Appliance storage location. The catalog is required to be used by all protected databases that send backups to Recovery Appliance.
Note:
Databases may use Recovery Appliance as their recovery catalog without also using it as a backup repository.
Administrators use Oracle Enterprise Manager Cloud Control (Cloud Control) to manage and monitor the environment. Cloud Control provides a "single pane of glass" view of the entire backup lifecycle for each database, whether backups reside on disk, tape, or another Recovery Appliance.
Recovery Appliance provides the following benefits:
