Method for automatically backing up digital data preserved in memory in a computer installation and data medium readable by a computer having the associated instructions stored in the memory thereof

A computer installation for the automatic backup of digital data to a remote backup system accessible by the computer installation via a data transmission network, comprising means for storage of digital data and a backup application for backing up at least part of the digital data to the remote backup system, the computer installation comprising:

• means for extracting operating information of the computer installation;
• means for analysing the operation information and means for determining settings of the backup application according to a result of the analysis;
• means for analysing the digital data stored by the computer installation and means for classifying the analysed digital data into a plurality of classes of differing priorities,
• wherein the backup application is configured to be executed on at least a part of the digital data, according to the determined settings and classes of priorities, and the computer installation further includes
• means for detecting a creation in the memory or a modification of a digital element;
• in response to the detection, means for analysing the digital element in order to assign a priority coefficient to the digital element;
• and
• means for executing the backup application on the digital element, according to the settings and the priority coefficient which is assigned to the digital element.
