Is an element of an internal control system established to maintain availability and restoration of critical processes in the event of interruption
Disaster Recovery Planning
What are the two goals of DRP

It indicates the earliest point in time in which it is acceptable to recover data
RPO
RPO and RTO: The RPO is determined based on what?
Acceptable data loss
RPO and RTO: It is possible to recover every data that was affected by the disaster (T or F)
False. It is impossible
RPO and RTO: What do you call data that is lost
Orphan data
It indicates the earliest point in time at which the business operations must resume after a disaster
Recovery Time Objective
RPO and RTO: The RTO is determine based on?
Acceptable downtime
The RTO includes business operations recovery only (T or F)
False. It includes supporting IT systems
RPO and RTO: What is the relationship of cost and technology with reference to time to disruption?
the nearer the RPO and RTO to the time of disruption, the higher the cost and technology
RPO and RTO: What can you employ for RPO and RTO with the lowest acceptable data loss and downtime?
For RPO: Data Mirroring, Real Time Replication
For RTO: Mirror Site/ Hot site, Dedicated Spare Servers and Clustering
RPO and RTO: It is the time gap within which the business can accept the unavailability of IT critical service
Disaster Tolerance
RPO and RTO: What is the relationship of disaster tolerance and RTO?
The lower the RTO, the lower the disaster tolerance
RPO and RTO: The RTO is focused on _____ solutions, while the RPO is focused on ___ ___ solutions.
Recovery; data protection
RPO and RTO: What are the additional parameters that are important in defining the recovery strategies?
Interruption Window
Service Delivery objective
Maximum tolerable outages
Recovery Strategies: the maximum period of time the organization can wait from the point of failure to the critical services restoration
Interruption Window
Recovery Strategies: What can happen if the interruption window is exceeded?
The losses incurred by the company becomes unaffordable
Recovery Strategies: Level of services to be reached during the alternate process mode until the normal situation is restored (minimum of level of serviceability to be achieved while restoring to normal operations)
Service delivery objective (SDO)
Recovery Strategies: The SDO is related to what?
Business needs (Critical operations)
Recovery Strategies: Maximum time the organization can support processing in alternate mode.
Maximum tolerable outages (MTO)
Recovery Strategies: After the MTO, different problems may arise especially if?
- The SDO is lower than the usual SDO
- The information pending to be updated becomes unmanageable
Identifies the best way to recover a system (may be on or many) in case of an interruption.
