How to create a strong but cheap Disaster Recovery Center (DRC) Site

The measurement of strong Disaster Recovery Center (DRC) site is simple. It measured in two ways: The RPO (Recovery Point Objective) which means how much data your company willing to lose when things go wrong and the RTO (Recovery Time Objective) which mean how long you're willing to go without service after disaster. The lower number your company has the stronger DRC you have.

However the measurement of cheap DRC can be vary, ranging from simple strategy such as invest in the correct type of equipment, or always improve to achieve the highest possible asset utilization rates. Here are 3 simple strategy to create strong but cheap DRC.

1. Avoid idle compute resources.
Calculate the number of servers needed to host critical interactive sessions, local batch jobs, and additional infrastructure severs, and avoid idle compute resources.

2. Use a tiered storage solution.
Match data replication mechanisms to the engineers' RPO and RTO definitions.
Implement a tiered data storage solution using a combination of Fibre Channel (FC) and Serial Advanced Technology Attachment (SATA) disks.

3. Offload main site backup.
Instead of backing up data at the main site, use the DR site's replicated data to create the backup copy.
