INITIATION SEQUENCES FOR PERFORMING PROTECTED COMPUTER OPERATIONS

摘要

A user's intention to perform an operation is confirmed by determining within a computer configuration a change in state of a write protection status. The change in state of the write protection status may be either from enabled to disabled, or from disabled to enabled. Determining the change in state of the status includes initially checking the state of the write protection status; subsequently checking the state of the write protection status; and comparing the state determined in the initial check with the state determined in the subsequent check. A predetermined period between the initial check and the subsequent check is provided, and the subsequent check is repeated until a change in the status is determined, or until either a predetermined number of subsequent checks has occurred and/or a predetermined time period has expired. The method can be used in backing up and restoring data of a headless server.
