Disaster recovery software helps businesses to take preventive action against catastrophic events, which have the potential to close the business due to damage of computers / networks / servers. The software essentially handles backup and restoration operations for different types of situations depending on the business. Generally disaster recovery software is a part of disaster recovery which is offered as a service solution to overcome such a problem.
There are many vendors in the field of disaster recovery software. Though, in essence, all offer backup and restoration solutions, their functions can vary widely depending on the software. Some software are intended for use with cloud computing backup whereas others depend on offsite remote backups. Generally, disaster recovery software is an‘always active’ monitoring watchdog that tracks any changes and ensures backup of those changes in real-time.
If required, some DR software offer instant recovery solutions. When the cloud is used as a backup, an instant failover option will be provided, so that all functions are routed to the virtual machines in the cloud and the entire switchover will be seamless.
Irrespective of the type of disaster recovery software used, IT teams must constantly monitor the system to see if it can meet the challenge of disaster recovery. Some other checks that should be constantly done are:
- Check and validate configuration consistency in both the production and disaster recovery environments. Any change in the production should be accurately mirrored in the disaster recovery environment.
- Over time, many changes occur in the IT field. There will be configuration tuning, patches, and alerts, maintenance etc. Such factors cause high volume of changes and such changes in the production field do not necessarily translate fully into the disaster recovery environment. If there is any such mismatch, which has not been detected and rectified, recovering data will be much more difficult.
Validation of changes that occurs in the production environment should be accurately mirrored in the disaster recovery environment and they should be constantly monitored by the IT teams. By using disaster recovery software, such mismatch can be detected and rectified before any damage is done that leads to data loss.
Effective disaster recovery software will monitor the following critical fields:
- The software should cover the entire IT environment. Functions such as application, servers, databases, message layers, operating Systems etc. should be covered. This will ensure that the entire system is being monitored in real time.
- The software should check even the basic level configuration parameters such as registry, configuration files, database entries, reference data etc.
- The software should have powerful analytics which will be able to classify any configuration change by both impact and criticality.
A disaster recovery software solution is a very effective tool in disaster recovery planning. For the disaster recovery software to function effectively, IT teams should ensure that the software provides the solution to recover all data that is critical for business operations. IT teams must ensure that they analyse and determine all critical aspects of the business before formulating the disaster recovery plan. A good plan, with ideal disaster recovery software, will lead to business continuity with the least downtime and revenue loss.
