What is a Disaster Recovery Plan

A ibm disaster recovery plan is a set of procedures to recover your data and applications from an unplanned event such as a natural or man-made disaster. It is a key element of your overall IT strategy and can be implemented using a variety of technologies. These solutions range from practicing a good prevention process to deploying advanced IT infrastructure technologies that can automatically save your data in near real time at a protected offsite location.

Your business can lose valuable time and money during a disaster, but if you have the right plans in place, you can minimize the impact on your business. By leveraging IBM cloud and storage solutions, you can ensure that your critical applications are backed up in case of an emergency.

DR solutions are typically deployed in two separate sites, with one active and the other passive. The DR site can be a completely different architecture than your production environment, which may require additional network connectivity or hardware and software resources to support the application. You can also deploy a single active and passive site, which is commonly referred to as a split-brain deployment. This approach is less expensive than a fully active and passive solution, but it requires that you implement more complex and costly failover policies.

Disaster recovery planning is a process that includes identifying the components of your IT infrastructure and the processes and policies required to keep them running. It can also involve testing the DR plan to make sure it works as intended. Depending on your company’s needs, you can choose between a point-in-time copy or instant recovery.

A point-in-time copy creates a snapshot of your database at a particular moment in time. This is a great choice for organizations that can tolerate losing some data and want to minimize the impact of a disaster. Point-in-time copies can be restored quickly after a disaster and provide rapid business continuity.

An instant recovery solution takes a snapshot of your entire IT environment and stores it at an offsite location. This approach is more affordable than a point-in-time copy but it can be slow to restore after a disaster and does not provide as much business continuity.

IBM provides a comprehensive disaster recovery (DR) service for Sterling Order Management. This service is designed to provide an industry-leading time frame for restoring processing capabilities to an offsite backup data center after a disaster. This service includes recovery procedures for the applications used by customers and Customer Support as well as the infrastructure of host systems and data communications.

The DR service is based on the Zerto virtual replication architecture. It uses a pair of IBM Storwize V7000 storage solutions. Each site has a VIOS server with multiple VM profiles. During the protection phase, the DR site deploys an emergency IBM Cloud Private environment. During the emergency deployment, Zerto re-creates each VM LUN from replicated data and redefines them inside the hypervisor. Zerto then prepares the replication solution to perform backward replication when the primary site becomes available again.
