In this episode I talk about the importance of being prepared for a disaster that takes your primary data center offline.

Being prepared to keep IT systems operating during or after a disaster is critical
What is DR, how does it work?
- How will you offer IT services if a fire destroys your data center?
- Email
- Voice
- Business Software
  - Billing
  - Accounts Payable
  - Payroll
  - CRM
- What servers will you use?
- How recent will the data on them be?
- What services and data will be available?
This should be driven from management as a part of business continuity
It should be driven by IT even if BC isn’t in place
Hosting
- On premises, separate facility
  - Up front cost
  - Maintenance
  - Space
- Data center
  - Ongoing cost
  - Maintenance
- Cloud
Scope
- What needs to be included?
  - Is restoring from nightly backups enough for some servers?
- RPO – recovery point objective
- RTO – recovery time objective
- Budget
Testing
- Soft failover
- Hard failover

Final Thoughts
- DR should be considered a critical part of every IT infrastructure, make sure you have it, that the scope is accurate and that it works.
