2015 Public Cloud Disaster Recovery Survey

Disaster Recovery Challenges and Best Practices

CloudEndure 2015 © 2

Executive Summary

This benchmark survey presents challenges and best practices of companies that host web applications in the public cloud. The results presented here are based on responses from 109 IT professionals from North America and Europe collected through an online survey. Some of the key findings of the survey include:

• The #1 risk to system availability is Human Error followed by Networks Failures and Cloud Provider Downtime.

• While the vast majority of the organizations surveyed (83%) have a service availability goal of 99.9% or better, almost half of the companies (44%) had at least one outage in the past 3 months, and over a quarter (27%) had an outage in the past month.

• The cost of a day of downtime in 37% of the organizations is more than $10,000.

• When it comes to service availability, there is a clear gap between how organizations perceive their track record and the reality of their capabilities. While almost all respondents claim they meet their availability goals consistently (37%) or most of the time (50%), 28% of the organizations surveyed don’t measure service availability at all. It is hard to tell how these organizations claim to meet their goals when they are not able to measure them.

• The top challenges in meeting availability goals are budget limitations, insufficient IT resources, and lack of in-house expertise.

• There is a strong correlation between the cost of downtime and the average hours per week

invested in backup / disaster recovery.

Annual Budget for Backup / Disaster Recovery vs. Cost of Downtime

Disaster Recovery budget is highly correlated to the cost of downtime. 91% of the organizations where the cost of a day of downtime is less than $10,000 have an annual backup / disaster recovery budget of less than $10,000, whereas 70% of the organizations with a day of downtime cost exceeding $10,000 have an annual backup / disaster recovery budget of over $10,000.
