Understanding Downtime
Disaster Recovery
Disaster 1% Unplanned 9%
High Availability (Continuous Operations)
Planned 90% Downtime refers to a period of time or a percentage of a time span that a machine or system (usually a computer server) is offline or not functioning, usually as a result of either system failure (such as a crash or routine maintenance.
Don’t Confuse Reliability with Availability! visionsolutions.com

Understanding the Cost of Downtime Revenue
Productivity
• Direct Loss
Number of employees affected X hours out times X burdened hourly rate
• Compensatory Payments • Lost Future Revenue • Billing Losses Financial Performance
Damaged Reputation • Customers • Suppliers • Financial Markets • Banks • Business Partners
Know your downtime costs per hour, day, week, etc.
• Revenue Recognition • Cash Flow • Lost Discounts (A/P) • Payment Guarantees • Stock Price
Other Expenses Temporary Employees, Equipment rental, overtime costs, extra shipping costs, travel expenses, legal obligations
Gartner estimates range from $106,000 to $183,000 per hour of lost revenue. visionsolutions.com

More than just replication, way more! Continuous Data Protection (CDP) allows for recovery from any previous point in time. Protect more than just the hardware. Make RPO a variable and RTO much faster Reverse data corruption fast.
“Data Recovery Has Never Been So Fast, Easy and Affordable”

Advantages of EchoStream
• •
Addresses the three biggest pain points in data protection – Backup Window Reduction, RPO and RTO improved Capable of creating a read/write clone of production data from any point in time – Easy testing against current production data (without

•
affecting replication) Improved quality as software patches, upgrades are rolled out Offload report generation processes
– Advanced data recovery capabilities – Pick the recovery point after the problem occurs, not before it

How EchoStream Works Ethernet (IP) network attachment
• Data Tap on Source Server
Network
captures changes – Writes to local buffer occur –
synchronously… …then are asynchronously transferred to the target server
• Replicates only changes • •
to production data Contexts used to maintain write order consistency Recovery Storage can be any heterogeneous storage

EchoStream’s Replication Process Production Server Primary Storage
1.
Applications write to primary storage as usual
2.
EchoStream maintains an exact replica of the Production Server’s data Copies all disk writes Ordered by time sequence Across an IP network
