What is the goal of recovery point?

In today's computer economy, businesses must respond to the risk of data loss and expensive downtime associated with hardware and software disorders, equipment failure, terrorist act and natural disasters. Within each analysis of business impacts, the administration of companies must set specific goals for recovery after the disaster, including the goal of the RPO (RPO). The aim of the point point is a retroactive period for which the data can be renewed after the disaster and still allow society to continue normal operations. In other words, RPO refers to an acceptable amount of potential data loss in terms of time that the company can tolerate. The Restore Point object determines the frequency of key backup of business data and technology connected to this process.

Although it might seem reasonable to maintain all data backed up up to a minute, the cost of it may be prohibitive, especially if the company wishes to store inFormation outside the web. Each company must carefully consider its real needs to restore critical information against the costs of the proposed recovery system. For example, banks and exchanges cannot tolerate any data loss that requires a current or continuous "RPO failure point". The medical office has critical data on patients and financial data about its computer system, but can restore operations if the information is renewed from the advance before, called the "closure of a business RPO". Finally, a teenager who plays games and surfs on his home computer can have "zero RPO", which means he doesn't have a serious need for backup.

In addition to the restoration of the recovery point, the company's continuity plan also includes a recovery time (RTO), a targeted time since the data did not renew. For example, the company may decide to restore normal activity within six hours of credible to minimize financial losses. Data acquisition systems used by a company must provide complete renewal of kriTical data in a six -hour window. While RPO determines the backup frequency, RTO determines the recovery technology. A variety of modality for backup and recovery from belts, discs, external hard drives, online storage and alternative physical pages connected by telecommunication systems provide different degrees of availability, security and speed of recovery.

Several key factors enter the target of the recovery point point. First, the company management must separate information that is absolutely necessary for basic operations to reduce the cost of replication and storage. If the company wants to reproduce and store all data, including uncritical data, it may have to reduce the replication frequency to contain costs. For systems of continuous recovery with data reliability during a replica -long catastrophe course, a disaster cannot be guaranteed. If the company wishes regional protection, with storage outside, the cost of maintaining dark fibers, the technology of the dense wool division (DWDM) orTelecommunications lines will require longer RPOS.
