Computer implemented method for operating a data storage device

Abstract

In order to improve a computer-implemented method for operating a data storage device, including an access management unit for a file system by which, in the event of an access request, generated by a process in a data processing device and transmitted to the data storage device, for a file of the file system, this file is made available for file access, wherein the improvement is such that this computer-implemented method is protected from malware, in particular ransomware, it is proposed that the access management unit should include a file securing unit by which, in the event of an access request for the file that is forwarded to this file securing unit, a file securing routine is started, that the access request should be blocked until a backup copy of the file has been created and stored, that the access request should then be forwarded to an access layer for the file system, and that access should be carried out by the access layer.

Dependencies are inferred from the claim text.
