Most large companies spend between 2% and 4% of their IT budget on disaster recovery planning; this is intended to avoid larger losses.
Once you have identified your critical systems, RTOs, RPOs, etc, create a table, as shown below, to help you formulate the disaster recovery strategies you will use to protect them. The following section details the elements in a DR plan in the sequence defined by ISO 27031 and ISO 24762. The seven tiers of business continuity solutions offer a simple method to define current service levels and associated risks. Procedures should ensure an easy-to-use and repeatable process for recovering damaged IT assets and returning them to normal operation as quickly as possible. The next section should define roles and responsibilities of DR recovery team members, their contact details, spending limits (for example, if equipment has to be purchased) and the limits of their authority in a disaster situation. Based on the findings from incident response activities, the next step is to determine if disaster recovery plans should be launched, and which ones in particular should be invoked. Located at the end of the plan, these can include systems inventories, application inventories, network asset inventories, contracts and service-level agreements, supplier contact data, and any additional documentation that will facilitate recovery.
The more detailed the plan is, the more likely the affected IT asset will be recovered and returned to normal operation.
This section defines the criteria for launching the plan, what data is needed and who makes the determination.
Technology DR plans can be enhanced with relevant recovery information and procedures obtained from system vendors. Continuity Logic’s Frontline Live 5™ is the first leader in Gartner’s Magic Quadrant Business Continuity (BCMP) software category that has effectively converged continuity, risk and compliance in a one easy to use cloud-based solution. Growing reliance on Information Technology, along with compliance and regulatory requirements has led many organizations to focus on business continuity (BC) and disaster recovery (DR) solutions.
DR, business resumption and emergency preparedness are three integrated components of a business continuity management solution. Disaster recovery addresses recovery of critical IT infrastructure such as hardware, software, telecom, network and data for bringing up the mission critical applications to support the business. Lesson Learned: A complete BCM solution requires the tight integration of emergency preparedness, disaster recovery and business resumption. The clear disaster scope definition will help in setting up the expectations very clearly and iron out all issues in the scope.
Lesson Learned: Provision for a DR solution should be mentioned clearly in the software agreement and coordination with procurement and legal is vital in handling software licenses for the DR environment. In general, DR solutions cost too much, requiring enormous investment in additional server and networking hardware to replicate existing data centers – increasing infrastructure needs accordingly.
It may be very difficult to convince management to purchase new hardware when it is known to everyone that new hardware is going to be kept idle until a disaster strikes the primary site.

One solution considered in those cases is to use the old hardware for DR and use the new hardware as production. In a time of disaster, there is a tremendous amount of pressure and stress to get everything back up and running and available to users.
Also, traditional recovery procedures involve several groups such as operating system, database, etc. Lesson Learned: Simple UNIX scripts can make the recovery steps less complex, avoid manual errors and reduce the recovery time substantially.
Another solution available is to have a snapshot solution along with SAN replication which helps to recover from the last snapshot. A disaster recovery plan is only as effective as the ability to communicate with and activate the recovery team. Global changes in business models, heavier reliance on information technology, and recent developments in disaster recovery technologies are forcing organizations to reformulate their DR solutions. The days of basic disaster recovery plans are gone.Having a solid disaster recovery program has moved up the priority list.
A complete solution for a seamless recovery.CareTech Solutions offers a full suite of disaster recovery services to help you meet your hospital's recovery objectives. Designed and built exclusively for healthcare.CareTech Solutions has a solid track record of working closely with its hospital clients to design better approaches to disaster recovery as their technology and needs change.
The Seven Tiers of Disaster Recovery was originally defined by Share to help identify the various methods of recovering mission-critical computer systems as required to support business continuity. In addition to using the strategies previously developed, IT disaster recovery plans should form part of an incident response process that addresses the initial stages of the incident and the steps to be taken. It is in these plans that you will set out the detailed steps needed to recover your IT systems to a state in which they can support the business after a disaster. This process can be seen as a timeline, such as in Figure 2, in which incident response actions precede disaster recovery actions.
Once the plan has been launched, DR teams take the materials assigned to them and proceed with response and recovery activities as specified in the plans. These are essential in that they ensure employees are fully aware of DR plans and their responsibilities in a disaster, and DR team members have been trained in their roles and responsibilities as defined in the plans. Check with your vendors while developing your DR plans to see what they have in terms of emergency recovery documentation.
When this happens, the application at the alternate location is incomplete and applications will not function as required in the event of a disaster.
Scheduler-based or script-based solutions are implemented for replication wherever it is not feasible or economical to replicate through SAN. Another solution may be to use repurposing software which can allow servers to be used as a staging or QA environment during normal circumstances and bring up the DR environment quickly when disaster strikes.

Some of the SAN replication solutions have the built-in feature of having the time stamp on the replication copies and enables recovery from the previous copies.
Some of the lessons and best practices mentioned in this document can be utilized to create viable and successful DR and business continuity solutions for clients. He is a certified professional and has hands on experience in implementing Disaster Recovery solutions.
In a disaster, whether natural or man-made, your hospital can't afford unavailable or lost data. Moving from traditional IT operations toward a "real-time healthcare" strategy requires a strong, scalable foundation of core IT capabilities – including an enhanced Information Security program that fully supports business continuity and disaster recovery. Learn how to develop disaster recovery strategies as well as how to write a disaster recovery plan with these step-by-step instructions.
This document lays down some of the best practices and learning for implementing disaster recovery solutions.
These cost and complexity challenges have effectively restricted or degraded many IT disaster recovery plans.
Simple UNIX scripts can be used to automate most of the steps in the recovery procedure which can simplify the steps and avoid any manual error in syntax and reduce the recovery time. Formulating a detailed recovery plan is the main aim of the entire IT disaster recovery planning project. The information shared in this document is based on the experience, obtained during the execution of disaster recovery implementation projects. Having a simplified and automated disaster recovery processes would eliminate the unnecessary time delay and manual errors during the recovery.
These steps are helpful to have a better recovery procedure to respond very quickly to any disaster incident. As a result, most companies are aware that they need to backup their digital information to limit data loss and to aid data recovery. Then define step-by-step procedures to, for example, initiate data backup to secure alternate locations, relocate operations to an alternate space, recover systems and data at the alternate sites, and resume operations at either the original site or at a new location. Here we can see the critical system and associated threat, the response strategy and (new) response action steps, as well as the recovery strategy and (new) recovery action steps.
