The Benefit of HA/DR


Understanding Downtime

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!

Understanding the Cost of Downtime

Gartner estimates range from $106,000 to $183,000 per hour of lost revenue.

Know your downtime costs per hour, day,

week, etc.

EchoStream Overview


EchoStream

• 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”

Data Protection Concepts


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

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

1. Applications write to primary storage as usual

2. EchoStream maintains an exact replica of the Production Server’s data

Copies all disk writesOrdered by time sequenceAcross an IP network

3. Prior to the Recovery Server overwriting data, the information is saved in an “undo” log

4. Recover the application’s data by selecting

5. While the snapshot is in use, data protection continues
