Disaster recovery is very beneficially most especially when the three-tier system of recovery is used. First, the three tiered recovery provides an option for the organization recovery system in case one fails when it is needed. For instance, the distrusted architecture gives an organization a backup system which will help it in case any system fails. The second benefit which an organization may derive from using a three-tiered system of prioritizing a disaster recovery is increase performance ( Strager et al., 2011). The use of three-tiered system increases the rate of productivity in an organization at a considerable rate. When using the three-tiered system, the organization can execute different or multiple tasks at once hence speed and quantity of work are enhanced which has the possibility of increasing the organization performance.
Alternatively, there is the intelligent DR architecture which solves disaster problems through a contextual approach by breaking up the server tiered and applications into the priorities and the technology proxy DR solutions. This is very important to the organization since it provides a flexible approach to the DR have the best tools leveraged at a reduced cost for a particular system and application for the organization. Moreover, in an organization, there are data at the top level which should not be lost by the organization since they are very critical. When the three-tier system of prioritizing recovery is used, it provides the organization data and protects the files which may be lost ( Bouali et, et al., 2017). The last benefit the organization will get from the three-tiered system is that the business continuity is a guarantee. The three-tiered system allows business continuity by allowing the servers which act as backups and the servers which work as storage servers to function when a disaster occurs, and other system fails.
Delegate your assignment to our experts and they will do the rest.
At the top level departments, there is automated failover with zero data loss, at the middle level of the organization, the system which is used at this offices are transactional integrity system with low RTO. The last one is at the base level departments where backup recoverable at the DR locations. Also, RTO and RPO can be used at this level.
