What is a differential backup?
Data that's been changed since the last FULL backup

What is a LUN?

What is RPO?
Recovery Point Objective - the amount of data that can be lost from a disaster event

What is operational recovery?
Recovering from data damage (accidental deletion or corruption)
Inline / Target-based / Source-based
How does having an active/active datacenter solution impact RPO/RTO?
Zero RPO/RTO
What is Data Domain's data invulnerability architecture (DIA)?
Data verification and self-healing technology that ensures data integrity to recover backups successfully and reliably
