Thanks. We'll let you know when a new response is added.

Are you asking how to plan for DR or how to recover in a DR situation?
For recovery, you foillow your plan.
Creating the plan is a long process.
You can take classes on this.
Start with what do you do in a total disaster – ie: something (fire, tornado, etc) totally wipes out you primary place of business. IT Dept, Acct Dept, etc.
Now you need to determine how long can you be out of business before you are totally out of business. What is the ROI on repliacation of everything you need for business continuity. What is “everything you need”?
For IT, do you have a backup site, Data replication or do you rely on backup tapes?
For a full DR plan you need to go through every aspect of your business and determine what you would need to keep the businnes running in case of a DR.
The amount of time you could actually be down is proportionally the amount of investment needed to develop a safe/reliable DR plan.
You really need to look at some books on this as we could write comments here forever and not cover all you need to plan for.

    This has the feel of homework?

    Very good Charlie Brown. I want to add my two bits worth. Number 1: Have an up to date copy of your resume in your own off site storage. Number 2: Run like hell. Seriously. Consider the types of disaster and how to prevent issues from becoming disasters. What I mean is this. A disk failure. Is this a disaster or just a severe issue? Granted, it is not good but it could be just a very severe issue. With a proper DR plan in place, tested, and proven, you can keep the business running. You can approach building a plan from several different ways. As you develop a plan, develop prevention. Take steps to make an issue that could become a disaster STAY just an issue. Discuss with management and get them on board with developing a DP/DR plan. A DR plan can be as detailed or as simple as you want/need it to be. I have been to a class on DR software. It mainly says in this type of situation, who should be notified, what steps should be taken. Of course, you can break this down into a million pieces. What do you really need? Build a organization chart of who is who with their responsibilities and contact information and who is their backup person- one to serve in their place if they are unavailable. Then list all of the types of issues or potential disasters you can think of and who to contact, what steps are needed to take place to make it seems like it never happened. Also, with any issue that could become a disaster; list the actual steps that were taken, the start/stop times, notes, and ways to improve the proceedure. Then test, test, test, test, test. A plan is worthless if it is not proven. Test your backup tapes weekly. Make sure you can restore from the beginning, middle and end of the tape. I had one system die found that the head on the tape drive was mis-aligned. Thus, no backup. I really did not like having to tell the CFO that I could not get all of his data back. Other seemingly small issues that can become disasters. Sabatoge, power failures, brown outs and power spikes, floods(moisture in a computer room is the number one killer), internet failures, hardware failures, even disgruntled employees. The number one thing to remember is GET STARTED TODAY !!! Disasters are notorious for being unplanned.

    what are the steps that has to taken place in disaster recovery? Step #1: Define "recovery". There is wide variation in what sites need for recovery. Do you need every business unit doing the same work within 30 minutes? How many business units do you have to cover? Or can your site handle a lot of work manually for a few days? (A week?) A recovery for me is almost guaranteed to be very different than for you. Step #2: Define "disaster". Is a site destroyed? Or is it just a portion of a data center? Is it over a wide region, e.g., the New Orleans flooding? A local building fire that makes a system unusable will be very different from a regional catastrophe. And both of those can have very different consequences depending on how Step #1 has been stated. You might need nothing more than a cycle of off-site backups in order to recover sufficiently in an acceptable time frame. Someone else might need redundant sites in separated regions ready to switch at a moment's notice. Without good definitions of "recovery" and "disaster", we can't guess what's meaningful for you. Tom

    As Tom has already said - Define disaster. I can see you at the bottom of the crater / floating on a door, with some tapes - half inch reels that would be - and needing to implement the company's disaster recovery.. You need to go and ask lots of questions to understand what the task is. and then ask for lots of momey - on a continuing basis - if you really want to be be able to be back in business and collecting the debts 48 hours after the flood / tornado / explosion / landslide / riots pass through. Start with google for a day - plenty of material on t'internet.

    Also define how long you can afford to be down? Hot site, remote site. DR plan is living document that changes all the time. Keep it current and test your plan.

    Disaster is a continuum. We started with how to handle small disasters that are likely to happen such as a snow storm here in Colorado. We did company-wide planning, not just IT. So we planned for how to clear the parking lot, etc. From the IT side, we started working on what things absolutely needed to be done for our customers and how we could do that from home if necessary. We figured that if we worked on the smaller, more likely disasters, we would be working toward plans for a big one. I see it as an on-going process. As a result we have improved our backups and our email and network access. Still working on other issues as funds permit, but we have a direction and are working on it.
