Typical disaster recovery plans leverage backup and/or replication to move data out of the primary data center and to a secondary site. Historically, the secondary site is another data center that the organization maintains. But now, companies are looking to the cloud to become a secondary site, leveraging it as a backup target and even a place to start their applications in the event of a failure. The problem with this approach is that it merely simulates a legacy design and presents some significant recovery challenges.
Webinar: What's Wrong with DRaaS and How to Fix it
1. What's Wrong with
Disaster Recovery as a Service (DRaaS)
and How to Fix it
Join us as we explain:
● Challenges with Traditional Disaster Recovery
● Why organizations are Using the Cloud for DR (DRaaS)
● Challenges that Cloud based DR (DRaaS) creates
● Alternative Approaches to DRaaS

Who Is Storage Switzerland?
3. Our Speakers
George Crump is the founder of Storage
Switzerland, the leading storage analyst focused on
the subjects of big data, solid state storage,
virtualization, cloud computing and data protection.
He is widely recognized for his articles, white papers,
and videos on such current approaches as all-flash
arrays, deduplication, SSDs, software-defined
storage, backup appliances, and storage networking.
He has over 25 years of experience designing
storage solutions for data centers across the US.
4. Our Speakers
Neil Glazebrook, VP Product Management, ClearSky Data
Neil leads the product management team at ClearSky. Throughout his career he has
served in various senior product management positions, bringing complex
networking and video technologies to market. Before joining ClearSky Data, Neil was
a product manager in Akamai's media business unit, and then in a channel sales role
managing six of Akamai’s largest media channel partners.
Prior to Akamai, Neil held senior product management roles at Cisco Systems over
the course of 13 years. During that time, he spearheaded the formation of Cisco’s
video networking business unit and was a key member of the integration team that
oversaw the Arroyo acquisition. He led early adoption of solid state drives for Cisco’s
service provider video product portfolio, helping drive down costs while dramatically
increasing streaming cache performance and session density.
Neil co-authored an IEEE paper on multicast IPTV distribution and error correction.
He recently earned an MBA with Honors from Babson College.

7. What Types Of Disasters Are There?
• Site Disaster
• Server / Application Disaster
• Storage System Disaster
• Operational / User Error
Users don’t differentiate anymore
8. Disaster Recovery Challenges
• User Expectations higher than ever
• Faster recovery
• Less data loss
• No matter the disaster type
• Application Explosion
• More apps to recover in a disaster
• Of course all these apps create more data
• Overall Explosion of Unstructured Data
10. Enter Disaster Recovery
as a Service (DRaaS)
• Data is Backed up or Replicated to the Cloud
• If there is a Disaster:
• Data and application is restored in provider’s cloud
• And is hosted by provider until primary data center can be
reestablished
• Recovery options:
• Provider restoration of data to their compute platform
• Mounting of the VM image on their backup storage
• Activating data on live volume (replication)
11. The DRaaS Advantages
• Organization does not have to pay for a full
secondary site
• Organization does not have to equip secondary
site
• IT does not have to go to secondary site to
execute recovery
• Provider “may” be able to assist with recovery
• Relatively easy to test
12. The DRaaS Challenges
• Networking issues to be resolved during recovery
• Return to operations time-frame is hard to predict
• Time to move data from backup storage to production storage
• How many other recoveries are going on (in a disaster could
be hundreds)
• Overkill for a site, server or storage disaster
• Which are far more likely to occur
• Difficult to pinpoint performance after failure
• At some point you still need to get data back to the on-prem
data center
13. The IT Dilemma
• Leverage DRaaS but put up with challenges
or
• Do it yourself and put up with expense,
complexity and risk
or
• Leverage edge computing and the cloud
for primary storage and DR
14. Primary Cloud Storage DR
Advantages
• Data is already in the cloud
• Does not need to move in or out
• Compute can be anywhere
• On-prem, alternate prem or in the cloud
But there is a latency problem...
15. Solve The Latency Problem
To Get DR Advantages
• Move Applications to the Cloud
• Compatibility, security and performance concerns
• On-prem cache
• But cache miss represents severe performance drop
• On-prem cache with second metro-
cache/tier
• Final data stored in cloud
