Hi,

I just want to throw something out there for opinions and viewpoints relating to a Disaster Recovery site.

Besides the live production environment, do you think a DR environment should include:
- pre-production environment
- QA Environment

......or would this be considered to be OTT and a waste of resources?

Thanks.

Disaster Recovery should include whatever is deemed 'mission critical'.

For most businesses, that would mean getting the production systems back up and running. In this category, relying on backups for those two systems should suffice.

However, if your business is software development and support, then you would probably need Pre-Production and QA systems also.

In thirty years of work with technology, whenever there has been some failure, all resources go towards restoring and supporting users and systems. Development takes a hiatus, or pause.

My first thoughts on the topic...

Kinda depends. Is your goal to keep the invoices and paychecks flowing for a few days or weeks while they restore power and mop the mud out of your server room, or to keep doing all or most aspects of your business for months or more while your main office complex and data center are rebuilt.

It depends who is paying for it and what they are prepared to pay for


You have to work out where you sit and based on that, you can then decide on your capacity needs. The recovery process should be the same for whichever you choose, else you will never be sure what you are recovering. Try to get as simple a process as possible that is generic for your servers.

If you are using a 3rd party provider, then often they will help you work things through. It is their business after all, so they want to help.





I hope that this helps,
