Disaster recovery plans are based on the data sensitivity of the company in question. It can be backed up either daily every night or each weekend. Unless data is backed up in a continuous backup system, data is totally safe. Deeply damaged reputation, frustrated costumers, revenue loss are among the unfortunate repercussions in the event of a disaster depending on the data recovery plan.
It’s a proactive site which allows one to have their servers and a live backup site up and performing well during a disaster. Simply, you have a duplicate of a real working environment in their center. Hot site hardware will be of similar configuration to the real production environment on the ground. This aspect makes it an ideal amalgamation test for pre-production tests. Hot sites also help provide some backup of the present versions soft ware’s and hence allowing faster recovery and cutover chances. Most organizations are finding that most hot site management are on the verge of becoming acceptable and alternative to having third party hosted hot sites
Cold sites are sites with rented spaces with power and connectivity that’s ready to receive equipment. Having recovery times of seven days, or more a cold site becomes ideal for businesses whose operations have been halted for an extended period. They also come in handy when warm sites and hot sites have disasters that take a long time.
It’s usually the clients obligation to procure equipment for a cold site in case of a disaster. A recovery plan for a cold site must clearly stipulate the process of procuring and delivering of equipment to the specific cold site when the disaster strikes.
This is a preventive site which allows one to pre-install hardware and have the bandwidth pre-configured. In the case of a disaster, one only does data recovery. As opposed to a hot site, a warm site relies on pre-installed backups for recovery. It, therefore, doesn’t require dedicated storage but instead takes advantage cheap storage. All parts of a warm site plus storage are shared among several clients. This means that most prerequisites for a hot site also apply here. Warm sites were in the past measured in days. Those that which relied on tape backups were clearly on the lower side of disaster recovery services spectrum. Disk backups have brought in the narrowing of the gap between the hot sites and warm sites. Almost all disaster recovery service providers are now offering electronic vaulting solutions. Recovery point objectives and recovery time options of warm sites are now less than a day. This is almost close to the recovery times given by hot sites.
The company uses hot site data recovery type. I do agree with the recovery strategy since hot site sites are less expensive as opposed to hosted sites. Hot sites can be implemented by outsourcing them instead of having them in the house. Disaster recovery services service providers rely on the plain fact that in case of a disaster, not all customers are affected at the same time.
Hot site hardware will be of similar configuration to the real production environment on the ground. This aspect makes it an ideal amalgamation test for pre-production tests. Hot sites also help provide some backup of the present versions soft ware’s and hence allowing faster recovery and cutover chances. Most organizations are finding that most hot site management are on the verge of becoming acceptable and alternative to having third party hosted hot sites. Many organizations have also learned that having a privately owned hot site is cost-effective so long as it is properly maintained and can also be made an integral part of almost all daily operational needs. Other clients will have to ensure that they do regular system audits checks to ensure that equipment configurations are sufficiently matched with the fabrication necessities for the disaster. Additional management activities are required for a more robust solution for instance; when a company wants to have a hot site coexisting with the production environment. Once a hot site is coexisting in the production environment, a seamless takeover happens in a case of a failure.
