Data backup is very important and infeatures it concerns business. Indeed, in the event of loss of information, as well as in the absence of the possibility of its quick recovery, the owners may suffer great losses. Every year all over the world, a huge number of commercial and non-profit organizations for one reason or another lose their data, as a result of which they cease their activities, and in some cases, they also exist. So how to protect your data from loss?
Today, there are many companiesworking in the service of computer technology and information technology. There are also many software products and solutions that can back up data, given the degree of complexity of each particular situation. Specialists involved in this issue will install and accordingly configure the software that is necessary for the successful preservation of information.
Data backup, which is embedded in any system operating on a commercial facility, allows you to:
- qualitatively and quickly restore the operation of the information system in the shortest possible time, if the basic data were completely or partially destroyed;
- create, and then maintain data archives;
- transfer large amounts of information between different media and systems.
Normally data backup systemincludes the server, as well as the control software installed on it. In addition, there are organized libraries that allow you to store data in yourself. Depending on how much information you have to save, as well as the speed of copying will depend on the type of library used. Hard drives, magnetic tapes or magneto-optical disks are offered as carriers.
The task of the control software is to back up data in accordance with the set schedule.
Сохранение информации в наше время строится на network based. That is why data backup systems must be networked, which means that they must ensure the safety of information from all nodes without exception.
Modern solutions (for example, NetApp) allowfacilitate the process of data recovery, as well as reduce administration costs. Here, in the course of operations, modified or new blocks are transferred, so that data backup is much faster, network traffic is reduced, and, and this is very important, capacity is reduced by 90%.
Due to the increase in the amount of information presentedmore and more requirements for the quality and capabilities of backup systems. The data are of great importance for business, and they need easy access in online mode. The load on the system recovery is constantly increasing, stricter requirements regarding the recovery time of information in case of failures. So the solutions that allow backing up data are constantly being improved.
