The most important thing to include in the outsourcing agreement for disaster recovery activities is the recovery time objectives (RTOs). RTOs are the maximum acceptable time frames within which the critical business processes and information systems must be restored after a disaster or disruption. RTOs are based on the business impact analysis (BIA) and the risk assessment, and they reflect the business continuity requirements and expectations of the organization. By including the RTOs in the outsourcing agreement, the organization can ensure that the service provider is aware of and committed to meeting the agreed service levels and minimizing the downtime and losses in the event of a disaster. The other options are not as important as the RTOs, although they may be relevant and useful to include in the outsourcing agreement depending on the scope and nature of the disaster recovery services.
