- RTO (Recovery Time Objective)
- The maximum acceptable length of time a system, application, or process can be offline before the outage causes unacceptable business damage.
- RPO (Recovery Point Objective)
- The maximum acceptable amount of data loss measured in time — how far back a restore point can be without causing significant harm.
- Business Impact Analysis (BIA)
- A systematic process that identifies critical business functions and quantifies the operational and financial impact of disrupting each one.
- Failover
- The automatic or manual switching of operations to a backup system, server, or site when the primary environment fails.
- Crisis Management Team
- The designated group of senior leaders and functional managers responsible for activating and directing the BCDR plan during a declared incident.
- Maximum Tolerable Downtime (MTD)
- The absolute longest period a business function can be unavailable before the organization suffers irreversible harm, such as regulatory breach or permanent customer loss.
- Hot Site / Warm Site / Cold Site
- Three tiers of backup facility readiness: a hot site is fully operational and can take over immediately; a warm site is partially equipped and needs hours to activate; a cold site is an empty facility requiring days to configure.
- Tabletop Exercise
- A discussion-based simulation in which team members walk through a disaster scenario to identify gaps in the BCDR plan without activating real recovery systems.
- Single Point of Failure (SPOF)
- Any component — hardware, software, person, or process — whose failure alone would halt a critical business function.
- Change Management (in BCDR context)
- The process of reviewing and updating the BCDR policy whenever significant changes to systems, personnel, vendors, or business processes occur.
