      • 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

            • 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

                    • 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.
