What Are Your Choices For Backup Storage
Tape
Disk
Disk Backup with Deduplication
Cloud
exagrid.com | 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”
exagrid.com | 6
Disk for Backup
Performance - Fast
Reliability - High
Cost - High
Where does Disk fit?
• Primary storage
exagrid.com | 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
exagrid.com | 8
Cloud for Backup
Performance - slow
Reliability - high
Cost – moderate to high
Where does Cloud fit?
• DR or “archive” copy of backups

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 location1

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

Disk Backup with Deduplication
Architectural Approaches
• Deduplication in the backup software to straight disk
• Inline deduplication with scale-up
• Landing zone with scale-out
exagrid.com | 13
Challenges of Software-based Deduplication
• Deduplication in the media server
• All data stored deduplicated
• Deduplication ratios are low
• Limited scalability
exagrid.com | 14
Inline Scale-up Appliances Fall Short
• Inline deduplication on the way to disk
• All data is stored in deduplicated form
• As data grows, only disk is added
• Restores are slow as data needs rehydration
exagrid.com | 15
Fastest Backups and Shortest Backup Window
Unique landing zone• Write backups direct to disk• Adaptive deduplication
Benefits• Fastest backups• Shortest possible backup window• Strong offsite RPO
exagrid.com | 16
Fast Restores, VM Boots in Seconds to Minutes
Unique 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

DR Scenarios
Data Center
Infrastructure to a Backup App
2nd Site
Hosted Co-Location
Hybrid Cloud

Insulating your company from Ransomware
The true cost of a ransomware goes far beyond the ransom• lost productivity • loss of data• loss of customer confidence• Go right out of business

Protecting your company from Ransomware Backup your data
• 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• Encrypt your backups at rest• Tape
Educate employee to just “ignore” suspicious emails or links• Test emails• Simulated attacks
Patch systems regularly Block appropriately (FW) Antivirus software
