Challenges ofBackup & Recovery


Ideal Backup & Recovery Solution

• Minimal Impact Backup• Backups finish quickly, with no impact on applications

• Backups consume minimal resources and storage

• Complete, Reliable, & Fast Recovery• All completed transactions are recoverable (zero data loss)

• Point-in-time recovery available (user error, ransomware…)

• Recoverability status validated & monitored in real-time

• And..Low Downtime Database Cloning & Migration• Refresh test/dev environments using production backups

• Move from legacy to modern OS platforms in a few steps

All Capabilities Scale-Out with Growing Database Environments


Most Backup Solutions Fall Short

• High Impact to Production Applications• Prolonged CPU & I/O load for full backups + dedupe

• Application performance suffers

• Inadequate Recovery Assurance• Changes since last backup may be lost

• Corrupt backups not easily discovered

• No comprehensive DB recovery validation & status

• Complex, Non-Scalable Cloning & Migration• Myriad of scripts/procedures left over the years

• Deploy larger and more backup servers and appliances

Cost and Complexity Rapidly Increase to Handle Scale

Recovery Assurance is a Costly Challenge

Source: Customer internal data

Regulatory Compliance Backup Issues

• Massive, Costly Offsite Tapes• Missing / Corrupt Backups• Slow, Complex Recovery• Non-Compliance Penalties

Recovery Appliance: Real-Time Database Protection

Generic Bit-Copy Backup Appliance

• Backup taken once a day• Data loss exposure: all transactions since last backup

Zero Data Loss Recovery Appliance

• Continuous real-time redo from database memory buffers for immediate transaction protection

Backup Savings




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

• 10X less backup processing on production servers

• 10X less backup network consumption

Fast Restore to Any Point-in-TimeNo Incremental Apply = No Load on Production Server

• Directly restore any virtual full

• All blocks referenced from virtual full are efficiently retrieved to create physical full

• Eliminates production server overhead of traditional restore and merge of incrementals

• Inherits scalability and performance via Exadata-based hardware platform
