Developing a Disaster Recovery Plan
1. Define (un)acceptable loss.
Before you develop a disaster recovery plan, decide how much you will lose if you don't.
That will help you decide how much time, effort, and money to spend on a
disaster/recovery plan.
2. Back up everything.
You have to make sure that everything is backed up-including data, metadata, and the
instructions you'll need to get them back.
3. Organize everything.
You have everything on backup volumes. But can you find the volume you need when
disaster strikes? The key to being able to find your backups is organization.
4. Protect against disasters.
Most people think about natural disasters only when creating a disaster recovery plan.
There are nine other types of disasters, and you have to protect against all of them.
5. Document what you have done.
You need to document your plan in such a way that anyone can follow your steps after or
during a disaster.
6. Test, test, test.
A disaster recovery plan that has not been tested is not a plan; it's a proposal. You don't
want to be in the middle of a disaster and discover that you have forgotten some critical
steps.
