The important thing to a good disaster recovery in IT is really a solution that is certainly fast enough without the need of exceeding budget. The best solutions where application users don't notice any downtime will definitely cost the most when it comes to extra hardware, software, as well as other IT resources. Even though it is fine to never acquire the best solution, the recovery solution really should be good enough to recover and restore business servers and applications in a reasonable period of time, which ideally must be measured in minutes rather than hours.
There are numerous pieces that require to be duplicated when examining a replicated environment. In general, the same number of computer hardware which is in the normal environment must exist in the replicated environment. Since the normal environment grows over time, IT departments should not forget to upgrade the replicated environment at the same time.
Once a disaster recovery solution has been selected and implemented, you have to test the replication itself. The test is to be sure all functions and procedures work as advertised. Additionally, it makes sure that IT personnel know very well what has to be carried out case of an emergency. Finally, the test also gives the business application users a practical expectation of the span of time the downtime will be prior to the application is restarted within the replicated environment.
Even after the most effective has become tested to be sure it works, tests must be run every once in awhile to make certain that the growing workload from the production environment does not outgrow the capabilities of the replicated environment. If the recovery is simply too slow, it might be the perfect time to consider an upgrade to make certain business continuance in case of a disaster.
There are several software solutions out there to perform disaster recovery. The expenses may vary considerably too. Generally speaking, solutions that lessen the downtime will cost more being that they are more pricey to implement with regards to both hardware and replication software.
Another solution that a great many have chosen to do is to create virtualized instances of the business application server. In case of an urgent situation where a geographical area has been wiped out, a copy of the virtual image that has been sent off-site beforehand can be used to run hardware located outside of the disaster zone.
