Questions to Consider:

What is the objective during disaster recovery period:
Minimum Basics function – i.e. online materials availability and course continuation?
Full Production Availability, including LDAP, Customizations/Building Blocks availability?
What is the plan for post – DR?
Business Continuity Service considerations:
Recovery Time Objective (RTO)
RTO is the time-measured objective to have corporate Business Continuity Service operation up and running from the point in time that Corporate is made aware of the client’s primary Corporate applications system failure.
Recovery Point Objective (RPO)
RPO is the objective to minimize the loss of the client’s database and file storage content by constantly backing up the client’s information no less than the time guaranteed under each service level.
Customizations & Configuration
Dependent on Client’s requirement and RTO & RPO objectives
The Human Factor:

Documentation
Disaster Recovery Procedures should be well documented.
Plan for the unexpected.
