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

The company must determine how long they can be without the computer. Then you can start developing a plan.

For instance, If they can only be down for minutes, they you need to be replicating your data on another machine. If days, then you need to make sure you have access to another machine to load data from your backups.

What to do if machine is OK, but building is destroyed.

Etc. A disaster plan can takes a long period of time to develop.

Then you need to test it.

You will need to do plenty of research (or hire someone who is experienced in this to assist or do it for you)

    You need to tell us almost everything about your system before we can tell you what a useful disaster recovery exercise would be. We need to know hardware components, software components, networking requirements, business requirements, types of workload, and more. We need to know what equipment you have available to act as your recovery site. And we need to know what your recovery requirements are -- what priorities are for getting which system elements working and when. -- Tom

    It also depends a lot on the type of business you do

    My all-time favorite DR exercise scenario starts with the CEO showing up early, locking the data center and telling everyone who shows up that the data center is off-limits for the day. A 'disaster' has happened and everything on the other side of the door is 'destroyed'.   The work for the day is to get the DR site up and running.   How many would make it through?   Tom

    All I can say from personal experience is get one in place and quick. Many years back (1987?) I was working as a night operator/programmer. There was a bad storm going on outside and I call the manager and asked if I should hold off on the IPL. He said no go ahead and do it. Well as the system was coming back up we took a power hit. We did not have a UPS on this s/38, and BOOM it crashed . When the power came back we tried to bring the system back but were out of luck. The drive that held the micro-code and address info was damaged. After IBM installed a new drive, we had to recover the system from tapes. Well they weren't as current as we thought because we limped by for about 2 weeks before we finally got our system back and fully functional. Prepare a DR as soon as you can.
