For example, can an application be down for 24 hours without significantly affecting the business, or would an outage lasting just minutes be catastrophic? Two key measures can help you assess the needs of your business. The first is the Recovery Time Objective (RTO), which is the amount of time a business process can be down. For 24x7 applications, the answer may be “none”. The second, the Recovery Point Objective (RPO), is the amount of data you can afford to lose. For mission-critical applications, the RPO could be the most recent transaction; for file servers, it could be last night’s backup. Once you have established the RTO and the RPO for your business, you can consider the hardware, software and services available that will provide you with the right level of protection against specific causes of data loss. Two examples illustrate how this might work: Tape backup effectively protects your systems against virus attacks because data can be restored from the most recent healthy backup. However, recovery time may be longer than your business can tolerate. Remote replication of data between sites will provide much faster recovery of a site disruption compared to tape. However, it will not offer the same level of protection against accidental deletion or virus attacks. NOTE: This slide is animated. Unfortunately, no single solution is right for all applications. Based on the importance of the data, the speed of recovery desired, the type of recovery desired (file or image), and the tolerance for data loss, different solutions are deployed – each at a unique price point. As we look at the graph, let’s first discuss the axis. On the vertical axis, we have the Recover
