However, for small businesses, disaster recovery may be deemed costly or an unnecessary expense.Disaster recovery is an important aspect of business continuity. Naturally, from a fiscal standpoint, it makes sense to build disaster recovery into your organization's budget, and with monthly subscriptions that range from less than $100 to a few hundred dollars for a cloud-based DR solution, it’s more affordable than you may realize.Disaster Recovery Concepts to Implement in Your BusinessOne reason why many small businesses skip over disaster recovery is a lack of understanding of its basic concepts.
There are certain methods to creating a solid disaster recovery plan that every IT manager should follow.
The Disaster Recovery Guide is intended to be a launch pad for those seeking help with the business continuity planning process.
Using detailed questionnaires and checklists, this MS-Word toolkit will help you review both your contingency practices and recovery arrangements. These steps will help overcome any writer's block that comes with the seemingly overwhelming task of creating a document such as a disaster recovery plan.
From a management standpoint, we provide a DR solution via Windows Azure Hyper-V Recovery Manager (HRM), that is integrated with System Center Virtual Machine Manager (VMM). The service itself is in Windows Azure and the provider installed on the VMM servers sends the metadata of the private clouds to the service, which then uses it to orchestrate the protection and recovery of the assets in the private cloud. It even works for heterogeneous deployments, wherein the networks on primary and recovery sites are of different types. These documents are cumbersome to maintain and even if someone made the effort to keep these documents up-to-date, they were prone to the risk of human errors by the staff hired to execute these plans.

The concepts of disaster recovery may have a technical nature, but aren’t as complex as one may believe.The recovery time objective, or RTO, is the maximum desired length of time between an unexpected failure or disaster and the resumption of normal operations and service levels. The scope of this plan is to define the recovery steps in the event of a domain controller failure. Creating a disaster recovery plan is considerably simplified by use of this template and guide. The easiest way to create your disaster recovery document is to start with a framework and then address the details.
Don't forget to include contacts for the business layer -- they will ultimately have to sign off that any recovery efforts were successful. With these facts in mind, the control plane of our solution (HRM) is delivered as a cloud service we call DRaaS (Disaster Recovery as a Service). For example, the replica virtual machine of Marketing is attached to Network Marketing Recovery since (a) the primary virtual machine is connected to Network Marketing and (b) Network Marketing in turn is mapped to Network Marketing Recovery. For example, in a quick glance customers can identify the last test failover of a plan or how long ago they did a planned failover of a recovery plan. The RTO defines the length of time that is allowed to pass between system failure and repair before the consequences of the service interruption become unacceptable.The recovery point objective, or RPO, is the maximum amount of data allowed to be lost, measured in time. The scope of this plan is to recover from a loss of SQL Server 2005 Integration and Analysis Services.

HRM manages multiple sites, as well as complex inter-site relationships, thereby enabling a customer to create a comprehensive DR plan. Some compliance requirements for organizations mandate the failover of workloads twice-a-year to the recovery site and then running it there for a week.
If you’re maintaining a data center, maintain an off-site failover device to monitor your system health and reroute traffic in real-time, to another data center if your data center experiences failure.ConclusionIn the end, businesses are far safer implementing disaster recovery plans in their operations. This is the heart of your disaster recovery plan and should include as many pictures, data flows and diagrams as possible. As part of PFO, the Virtual Machines are shut-down, the last changes sent over to ensure zero data loss, and then virtual machines are brought up in order on the recovery site. The key to the process layering diagram is in building a complete high-level picture of the scope of the Windows disaster recovery plan. In the interrogation stage of the disaster recovery plan, you begin to ask questions, fill in the gaps and ultimately gather the knowledge points that currently reside with the key players in your organization. A scope statement, process layering, interrogation and a contact list become the skeleton of your DRP document, and you can use the document for more than just a DRP plan to have on file.
