2. DISASTER RECOVERY SOLUTIONS CONTRASTED USING COMDISCO CUSTOMER DATA Fig. 3 shows recovery time lines for a number of recovery techniques decomposed into stages of recovery. This chart is based upon actual customer data accumulated by Comdisco Recovery Services. The horizontal axis shows the time of failure as '0' hours, with Hours of Lost Transactions (Recovery Point Objective) to the left (negative) and Hours Required to Resume Business (Recovery Time Objective) in the positive range. Recall that RPO and RTO are planning objectives, and are noted in Figure 3 to show their corresponding term - and measured experience - for each recovery technique.
