Snapshots have been a key feature of primary storage infrastructures that IT professionals have relied on for years. But storage systems have traditionally been able to support only a limited number of active snapshots. And snapshots, being pointers and not actual data, are also susceptible to a primary storage system failure. As a result, most IT professionals use snapshots sparingly for protecting data. In this webinar Storage Switzerland and Nexenta show you how primary storage can be architected so that snapshots are able to meet almost all of the data protection requirements an organization has.

1. Learn How Snapshots CAN be Backups

1. The types of snapshot technologies
(they’re not all the same)
2. The weaknesses of snapshots
3. How to create a primary storage architecture
that overcomes these weaknesses
4. The benefits of a primary storage
architecture that protects itself

Oscar Wahlberg is a Director of Product Management at Nexenta. As a part of the team at Nexenta he
runs the product management team for NexentaStor and NexentaEdge - a new object cluster storage
product. Before joining Nexenta he was with Symantec and Veritas Software where he lead the
product management team for their file system products and emerging storage solutions.
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

Nexenta Company Highlights

5. Polling Question
What is your biggest data protection
challenge?
A) Getting backups done on time
B) Protecting data more frequently
C) Meeting each application’s RPO/RTO
D) Lowering the cost of data protection
E) All of the above

6. Polling Question
What is your biggest data protection
challenge?

7. State of Data Protection
• Applications are increasing in number
• Application data is growing
• Unstructured data is growing
• RPO/RTO is becoming
increasingly strict

8. The Storage Switzerland Data
Protection Philosophy
● Set Service Level Objectives
● Develop a “3-2-1” Data Protection
Strategy
● Develop a Tiered Recovery
Strategy

9. Set Objectives
Don’t Broker Agreements
● Ask any user or application
owner how much data can
they afford to lose and guess
what the answer will be?
● NONE!
● Service Level Objectives are
set by IT based on their
known capabilities and
intrinsic understanding of the
environment

10. What is a 3 – 2 – 1 Data Protection
Strategy?
3 Copies of Data
Not 30
2 Types of Media 1 Copy off-Site

11. What is a Tiered Recovery Strategy?
Snapshots (RPO/RTO)
On-Site Disk Backup (RTO)
On-Site Archive (VRO)
Off-site (GRO)

12. Where Traditional Backup
Falls Short
• Once a night protection is
not enough to meet RPOs
• Data transfers from
protection storage to
primary storage too slow
• Recovery in Place creates
as many problems as it
solves

13. Primary Storage Has To Carry
More of the Backup Burden

14. The Advantages of Snapshot-Driven Data
Protection
• Protection copy can made
instantly and clean
• Data is stored in native form
• Protected copy accessible
from other servers or VMs

15. Addressing the Weaknesses of
Snapshots
• Snapshots are vulnerable to
storage system failure –
Implement two systems on-
site, snapshots on both
• If the site fails so do your
snapshots – Implement a 3rd
system off-site

16. Addressing the Weaknesses of
Snapshots
• Storage system has to support a high
number of active snapshots
– Use a re-directed
snapshot technology
• Long term retention of data
eventually gets expensive
– Backup up snapshots to
disk/cloud/tape for retention
and indexing
(meets the “2” in 3-2-1 strategy)

17. • Storage systems are coming down in price
dramatically
• Software-defined storage promised to drive that
price down even further, while maintaining
features and performance
• SDS also introduces
flexibility
