Home > Disaster LevelsThere are three different types of Disaster levels. They are Full Disaster, Partial Disaster, and Minimal Disaster. Full Disaster:In Full Disaster total destruction of all operations and production systems will take place. Partial Disaster:In Partial Disaster there are certain portions of operational and production systems which have been destroyed. This results in a partial recovery of the files. The Partial Disaster consists of one machine going down and restores from backup or on online networked source. Minimal Disaster:In Minimal Disaster there are small portions of operation environment which have been harmed. Virus outbreaks and file deletion may cause minimal disaster. These disasters is recovered by using undelete software or backup tape restores. The Establish Disaster Recovery team consists of a team leader that will carry the project and have authority over the process and influence in the company’s managerial department. The process from standpoint that when the disaster emerges everyone concerned in the recovery needs to be contacted. The main aim of the Disaster Recovery pack is to establish the essential documentation and respective contact details of each member. The telephone lines and access control becomes a disaster on their own adequately plan. The reason is to have detailed and updated documentation so that generic staff can restore the complex customized systems. The systems are dynamic and challenging to document and restore. A document that is not updated can be considered useless as pertinent information may be missing that is required to restore the environment. It should be the responsibility of the DR team leader to ensure that the DRP document and any annexure and any other pertinent information must be updated. No compromises on this one, it is high risk and if this process fails then your DRP is compromised. Make sure configuration management documents are updated. Configuration documentation is a fallback in case a change causes a disaster. This is why the change control is filled out before the change is made and then signed off after the change is made. This is the same reason that the changes are implemented on a test system. Update all the documentation using track changes may help, or saving a new version each time, or using version control solutions. Ensure a copy of all documentation is offsite and updated. All documentation must be sent offsite once it has been updated. When a disaster happens it is highly likely that the documents will also be destroyed. It is therefore important to ensure offsite storage of all of your DRP documentation. Ensure that the documents are stored in a safe place that insures integrity and confidentiality of these documents as they are likely to contain sensitive information. Ensure that all information is protected and stored in a secure location. A daily back-up of all data is taken to tape and stored offsite in the safe environment. There are other updated disaster levels which are latest and can are available in the market for the latest version. |
