Embodiment Construction
[0037] When the snapshot backup is used in the prior art, there are following problems: when there is a snapshot backup in the system, when the operating system executes, in order to improve the processing speed of the system, the mapping table accessed by the storage device is usually in the system memory, and the operating system access The address is a logical address, which is converted into a physical address on the digital storage device through the mapping table. If the restore command is sent at this time, the system will reload the mapping table. If the modification of the system disk is involved, it will directly lead to the crash of the OS.
[0038] In view of the above problems, the present invention provides an information processing method, which is applied to a first electronic device, where a digital storage device is installed, and when the operating system in the electronic device is running, if necessary, the digital storage The device performs a snapshot swi...

The invention discloses an information processing method and an electronic device. When an operating system in the electronic device is running, if it is necessary to perform a snapshot switching operation on the digital storage device, the method includes: judging whether the snapshot to be restored is stored There are preset sensitive files, and the first judgment result is obtained; if the first judgment result is yes, then the restore command for controlling the digital storage device to perform snapshot switching is stored in the digital storage device; when the system restarts or powers up again Afterwards, the restore command is triggered during the running of the system boot program before the operating system is started, and a snapshot switching operation is performed on the digital storage device. The method and device disclosed by the invention solve the problem in the prior art that if there are sensitive files during snapshot switching, the system crashes.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to an information processing method and electronic equipment. Background technique [0002] With the continuous development of computer technology and network technology, the level of information technology has been continuously improved. After mankind has entered the 21st century known as the information society, massive data-based applications such as digital communications, digital multimedia, e-commerce, search engines, digital libraries, weather forecasts, geological exploration, and scientific research have emerged, and various information presentations Explosive growth trend, storage has become the center of information computing technology. Application requirements for storage systems continue to increase, and storage capacity continues to upgrade, from GigaByte to TeraByte, PetaByte, and ExaByte, and it becomes even larger. At the same time, the dependence of modern e...
