Disaster Recovery Considerations

May 23, 2010

What is it

“Ability to recover from the loss of a complete site, whether due to a natural disaster or malicious intent.”

“A plan of action to recover from an unlikely event of a severe or catastrophic business disruption.”

It’s NOT a planning for Mean-Time-To-Recovery (MTTR) from daily operational risks.

MTTR Choices

On-Demand, Redundant Scaling Technologies

Use of attached clustered storage allows quick use of client growth

2N Redundancy at Core Infrastructure Level

Burstable, Redundant Internet Connectivity

Load Balancing

Dual Core CPU, Caching, Hyper-threading

Clustering Technology

Recovery Oriented Choices:

Autonomic Capabilities – Datacenter / Network / Systems

Warm Standby (rack, stacked and powered up)

SnapMirror Technologies

Oracle DataGuard & RMAN Technologies

Cold Standby

“Platinum” Service Contracts from Service Providers and Vendors

N+1 Redundancy capabilities at client level

Levels of Data Backups

1st level backup:

Using snapshot technology, file systems & database backed up on Network Attached Storage systems

2nd level backup:

Using NetApp NearStore devices, 1st level backups are stored online, off-site for 30 days

3rd level backup:

Weekly backups are stored in tape, off-site for 30 days
