Purpose: This is a worksheet that should be completed by the Application Owner in order to identify the information needed to recover and continue operations during and following an emergency, incident, or disaster and identify mitigation actions to reduce loss.
In particular, The Application Owner is asked to identify the RPO (Recovery Point Objective) and RTO (Recovery Time Objective) of their application:
Please consider the following aspects of your application when filling out this form:
Timing | Duration (RPO) |
Identify the points in time when interruption would have the greatest impact (e.g. season, end of month/quarter, etc.). | Identify how long it will take before qualitative and/or quantitative impacts will occur (e.g. < 1 hour, > 1 hour, < 8 hours, > 8 hours, > 24 hours, > 72 hours, > 168 hours, etc.) |
Qualitative Impacts | Quantitative Impacts |
|
|
Timing | Duration (Hours) | Qualitative Impacts (Operation) | Quantitative Impacts (Financial) |
Calculating the Recovery Time Objective (RTO) involves analyzing the qualitative and quantitative impacts of a potential disaster and determining the acceptable downtime for your systems and applications.
Here's a step-by-step process to calculate the RTO from the provided list of impacts:
Step 1: Determine the maximum financial loss tolerable from the application. Contact your financial analyst and discuss with them what loss is tolerable before there would be significant ramifications.
Step 2: Compile Qualitative and Quantitative Impacts. Review the list of qualitative and quantitative impacts and assign a daily financial value to each impact.
Step 3: Calculate Recover Time Objective. Sum the values of each impact in Step 2. Divide this value by the maximum loss tolerable determined in Step 1. The resulting number is the RTO.
For example, if the maximum financial loss tolerable was set to $30,000 and the daily financial value of all the qualitative and quantitative impacts was determined to be $1,500, the formula would be 30,000 / 1500 = 20 days. The recovery time objective would be 20 days, which means the application could be down for 20 days before unacceptable financial ramifications would occur.
