This document introduces Oracle's Zero Data Loss Recovery Appliance, which provides a new approach to protecting Oracle databases. Traditional backup appliances treat databases as files and copy them periodically, which can slow production and leave gaps in protection during backups. The Recovery Appliance uses real-time redo transport to instantly protect ongoing transactions with no data loss. It offloads backup processing and scales to protect all databases, providing database-level recoverability without impacting production. Customers have achieved faster restores, reduced backup windows, capacity savings, and elimination of data loss.

Key Database Protection Goals
• Business Goals
– Never lose critical business data
– No impact on business applications
• I.T. Goals
– Ensure database level recoverability
– Centralized service to protect all databases
Current backup solutions fail to achieve these goals

Backup Appliances Are Not Designed for Database
Treat Databases as Just Files to Periodically Copy
Daily Backup Window
Large performance impact on
production
Data Loss Exposure
Lose all data since last
backup
Many Systems to Manage
Scale by deploying more
backup appliances
Poor Database Recoverability
Many files are copied but
protection state of database
is unknown

Data Protection: Still A Complex Task
• Significant challenges
for data protection?
• #1: Backing up and
managing increasingly
large data volumes

Recovery Appliance Unique Benefits for Business and I.T.
Minimal Impact Backups
Production databases only
send changes. All backup and
tape processing offloaded
Eliminate Data Loss
Real-time redo transport
provides instant protection
of ongoing transactions
Cloud-Scale Protection
Easily protect all databases
in the data center using
massively scalable service
Database Level Recoverability
End-to-end reliability, visibility,
and control of databases - not
disjoint files

Recovery Appliance: Data Guard Like Protection for all Databases
Generic Bit-Copy Backup Appliance
• Backup taken once a day
• Data loss exposure: all transactions since last backup
Zero Data Loss Recovery Appliance
• Uses Data Guard continuous real-time redo transport
from in-memory buffers to immediately protect
ongoing transactions
Protected
Databases
Data loss is inherently bad.
Even worse..it creates massive consistency issues across databases

Space-Efficient “Virtual” Full Backups
• After one-time full backup, incrementals
used to create virtual full database
backups on a daily basis
• Pointer-based representation of physical
full backup as of incremental backup time
• Virtual backups typically 10x space efficient
• Enables long backup history to be kept with
the smallest possible space consumption
• “Time Machine” for database

Fast Restore to Any Point-in-Time
No Load On Production Servers to Merge Old Backups
• Directly restore any virtual full backup
• All blocks referenced from virtual full are
efficiently retrieved
• Eliminates production server overhead of
traditional restore and merge of

CUSTOMER PERSPECTIVE
ZDLRA has also introduced faster recovery times
so now we’re able to recover and restore in a
matter of 2 to 4 hours instead of previously where
we had an average of about 20 hours of
restore time.
