2. Agenda Backup Storage Choices 3-2-1 Backup Rule
Traditional Backup Storage Challenges
Deduplication – Good or Bad?
Backup-to-disk Appliances

3. What is a Company’s most important asset?
Employees?
Patents?
Reputation?
Data?

4. What Are Your Choices For Backup Storage
Tape
Disk
Disk Backup with Deduplication
Cloud

5. Tape for Backup Performance – Slow backup and restore
Reliability – Less than disk
Cost – Low to moderate
Where does Tape fit?
Long-term “regulatory” retention
“Archive”

6. Disk for Backup Performance - Fast Reliability - High Cost – High
Where does Disk fit?
Primary storage

7. Disk Backup with Deduplication
Performance – moderate to fast
Reliability - high
Cost – low to high
Where does Disk backup with Deduplication fit?
“Operational” retention
“Regulatory” retention

8. Cloud for Backup Performance - slow Reliability - high
Cost – moderate to high
Where does Cloud fit?
DR or “archive” copy of backups

9. 3-2-1 Backup Rule
Maintain at least three copies of your backups Store backups on at least two different types of media Keep one of the backups at a different location 3 2 1

10. Traditional Backup Storage Challenges
As data grows:
Time to backup grows
Time to restore grows
Time to offsite grows
System breaks – Resulting in disruptive fork lift upgrade 1 2

11. 5 Considerations for Hyper-converged Secondary Storage for Backup with Deduplication

12. Disk Backup with Deduplication
Architectural Approaches
Deduplication in the backup software to straight disk
Inline deduplication with scale-up
Landing zone with scale-out

13. Challenges of Software-based Deduplication
Deduplication in the media server
All data stored deduplicated
Deduplication ratios are low
Limited scalability

14. Backup Application Inline Deduplication to Disk
Inline deduplication in the media server
Slower ingest
Longer backup window
Can only deduplicate native backup data
All data is stored in deduplicated form
Slow restores, VM boots, and tape copies
Deduplication ratios are low
Uses more disk than target appliances
Uses more bandwidth to replicate
Limited scalability
Backup window grows as data grows

15. Fastest Backups and Shortest Backup Window
Unique / integrated landing zone
Write backups directly to disk
Avoid compute-intensive deduplication
Adaptive deduplication
Benefits
No inline processes to slow backups
Fastest backups
Shortest possible backup window
Strong offsite RPO

16. Fast Restores, VM Boots in Seconds to Minutes
Unique / integrated landing zone
Most recent backups are in undeduplicated form
Eliminates data rehydration
Benefits
Restores as fast as disk
Tape copies as fast as disk
VM boots in seconds to minutes

17. Fixed Length Backup Window

18. Infrastructure to a Backup App to ExaGrid appliances
DR Scenarios
Private Cloud
ExaGrid DR appliances in a customer’s 2nd data center
Data Center
Private Cloud
ExaGrid DR appliances in a 3rd party hosting/colo facility
Hybrid Cloud
ExaGrid DR appliances in a 3rd party cloud provider
Pay by the GB/mo. – OPEX expense
Infrastructure to a Backup App to ExaGrid appliances
Public Cloud
For example, AWS
Adaptive deduplication deduplicates and replicates in parallel
50:1 WAN bandwidth efficiency
Bandwidth throttle and WAN encryption for data replication
Configure the disaster recovery site to all repository to save cost

19. Multi-site Data Center Disk Backup Topology
Multi-site Architecture
16 locations in a single group – spoke and hub
50:1 WAN efficiency across all sites
Management from single UI
Cross-site protection between sites
Consolidated DR copies of backup reduces costs

20. Stress-free Redundancy and Security
Redundant Hardware
RAID6 with a hot spare drive guards against simultaneous disk drive failures
Redundant power supplies
NIC teaming
Security
Optional data encryption at rest
FIPS compliant / 256-bit AES
Occurs at the drive level in nanoseconds
Does not impact backup performance
WAN encryption for secure data transfer

21. Personal Touch - Maintenance and Support
Phone and Support
Assigned level 2 customer support engineer
Support staff are subject matter experts in backup applications
Customer Installable and Serviceable
Self-installable with phone support and WebEx
Self-serviceable hardware replacements, next business day delivery
All Releases Provided
Point and full releases – includes all new features
No license fees to track or renew
Health Status Monitoring
ExaGrid monitors and notifies
No additional charge – All included in support program

22. Fixing the Economics of Backup
Traditional Vendors
Sell at a low price and then raise the price on future purchases
ExaGrid fixes the price for all
future purchases – price protection
Price Protection
Sell one year support and then hike the price in year two and beyond
ExaGrid limits the increase to
3% per year
Maintenance $
Maintenance is a % of list price
regardless of hardware cost
ExaGrid’s maintenance is a % of the hardware price you pay
Maintenance %
Front-end controller architecture requires replacement to grow
ExaGrid appliances have all resources, add to scale-out system and grow
Forklift Upgrades
Need to plan out data growth to try and buy the right front end controller
ExaGrid allows for appliances to be added to a scale-out system
Guesswork
Products constantly discontinued and high maintenance costs charged
ExaGrid supports all models forever… mix and match any appliance
Obsolescence
Pay for installation, full versions, replication, HW replace
ExaGrid includes installation, full versions, replication, HW replace
Hidden Costs
