History[ edit ] Disaster recovery developed in the mid- to late s as computer center managers began to recognize the dependence of their organizations on their computer systems. At that time, most systems were batch -oriented mainframes which in many cases could be down for a number of days before significant damage would be done to the organization. As awareness of the potential business disruption that would follow an IT-related disaster, the disaster recovery industry developed to provide backup computer centers, with Sun Information Systems which later became Sungard Availability Services becoming the first major US commercial hot site vendor, established in in Sri Lanka. During the s and 90s, customer awareness and industry both grew rapidly, driven by the advent of open systems and real-time processing which increased the dependence of organizations on their IT systems.
RRC 4 MAC I Remote recovery using near-synchronous replication of data as well as dedicated, pre-configured, and operational processing capability at the designated recovery site. Any solution of this type must be identified within the relevant SLA.
In addition, any supporting documentation must be linked to, or referenced within, that SLA. Remote Recovery Options Geographically remote recovery differs from an operational recovery in that it assumes the primary processing environment is no longer operational or no longer accessible.
In that situation, the only alternative is to cease processing until the primary environment is available or to move the processing to an alternate location. The RTO timeline is driven by the use of backups on magnetic media to restore all required backup data to storage capacity pre-positioned at the recovery site, as well as the use of hardware that has not yet been configured.
The RPO is driven by the frequency of backups stored off-site from the primary processing facility. For this level of recovery to be effective, a corresponding hardware and software infrastructure needs to be available and operational at the remote recovery site.
This approach is designed to use shared resources at a single site to provide continuity for production requirements.
Because the shared resources are designed to be used by multiple sites running various applications for multiple partners, the resources are installed in a fairly "vanilla" configuration. Upon notification that an outage has occurred, DISA personnel will begin customizing and configuring the infrastructure to accommodate the incoming processing.
Upon the restoration of the primary production facility, the processing will be removed from the remote recovery site and returned to the primary site.
At that point, the shared resources will be returned to their default configuration. Remote Recovery - Combination 1. The RTO timeline is driven by the use of "Shared COOP" resources that will be configured, at the time of an outage or exercise, to match the associated production environment.
The RPO timeline is driven by the use of SAN-based data replication between the production environment and the recovery location. For this option to be effective, it requires the partner to select not only the appropriate storage option, but also the Shared COOP processor option.
The timeline is driven by the use of data backups stored at the remote recovery site in combination with dedicated and pre-configured server resources available there. For this option to be effective, it requires the partner to select not only the appropriate storage option, but also the appropriate remote dedicated processor offering.
The timeline is driven by the use of data replication to create near-instantaneous backups stored in an online status at the remote recovery site. This approach, in combination with dedicated, pre-configured and operational server resources, can provide assurance of minimal processing interruption with virtually no data loss.
For this option to be effective, it requires the partner to select the appropriate storage option and an infrastructure to be resident at the recovery site that can be brought online in less than 30 minutes.
Any hardware solution for recovery requirements this stringent will be developed as a customized solution. Customized Fail-Over It is possible that mission requirements for a particular application, or suite of applications, are not adequately addressed by any of the standard Remote Recovery Combinations defined above.
For example, it may be that a workload balanced production environment is in place and the desired Continuity of Operations COOP solution is to have the environment sized and configured to absorb the loss of one or more elements of the environment.
Assuming that the sites are geographically separate, that would be a feasible solution. If the partner does determine that a fail-over solution is desired and that the pre-defined approaches are not adequate or preferred, then a customized fail-over solution can be developed and implemented.
Any solution of this type must be identified within the relevant SLA and supporting documentation must be appended to or referenced within that SLA. Rates Please see current rate books on Mission Partner Portal.
