Method for saving computer data
First Claim
1. A method for saving computer data which consist of transferring the data to be backed up from a client computer to a buffer memory formed by the hard disk of a backup server, organised into a plurality of volumes with predetermined sizes, and then transferring the data from the said buffer memory onto the permanent medium (for example a magnetic cartridge), characterised in that a unique sequence of data for each of the said volume (basic data) is recorded on the said permanent medium after each of the volumes and after the transfer onto the permanent medium, the method also comprising a step in which a database is created in which the basic data are saved.
