The causes of incidents on the information system infrastructure can be diverse: hardware failure, software failure, backup failure, cyber attack, human error, natural disaster, etc.
Companies are increasingly dependent on their information systems, and are therefore threatened, whether by security problems, data loss or hardware failures. However, it is clear that these risks are often poorly understood.
As the statistics indicate , it is not a question of knowing whether or not the information system of a company will one day encounter a disaster, but rather of knowing when it will occur .
The establishment of the recovery plan is necessary in order to minimize the time to return to normal operation of the information system after a major incident.
