47 Risk Mitigation: Faster Protection Snapshot copy Safeguard data up to 98% faster Creates instant point-in-time Snapshot copies Has near-zero impact on performance Enables you to back up when you want, as often as you want to prevent data loss Restore faster, to eliminate risk of downtime Snapshots revert to specific point in time Meets tight recovery time objectives Uses a single command to restore, minimizing downtime Until recently the backup took several hours. With NetApp we have a time saving of at least 18 hours and were able to eliminate the tape backup. Pekka Purontaka, Storage Manager AFA Insurance 47
