Problems solved by technology

[0006] There will be differences in system settings and hardware drivers between different PDAs. If simple data restoration (replacement) is performed by the above method, it is often due to different PDA hardware, system files / drivers, registry, application programs and various applications. There are discrepancies between programs that can cause system crashes
[0007] Furthermore, even if there is no problem of the aforementioned system crash (for example, the backup data and the restore data are all the same PDA), it is known that the backup / restore program that originally generated the backup data file must be installed first when restoring the backup data (because after the hardware reset All programs disappear) to restore the data, thus causing inconvenience to the user

Embodiment Construction

[0025] Due to differences in system settings and drivers between different electronic systems, if only simple data restoration is performed, the existence of these differences may lead to the collapse of the entire system. Hereinafter, a personal digital assistant (PDA) will be taken as an example to illustrate the present invention, but the present invention should not be limited thereto. PDA data / programs can be roughly classified into system files / drivers, registry, user-installed applications and their dynamic-link library (DLL, dynamic-link library), application data generated by applications, and PIM data Wait. The system file / driver is usually built in the read-only memory (ROM) of the PDA, because it cannot be overwritten, and will not disappear due to a PDA hardware reset (hardware reset), so no backup is required. The registry is the configuration data file of the entire system. The registry is not applicable to different PDAs, so simple restoration / replacement cann...

Abstract

A method for reducing backup data in electric system, which includes supply backup data file containing at least one using date, then search whether there is using program corresponding to the using data in registration form of the electric system, if there is, reduce the using data, otherwise, do not reduce it. The invention has supplied another method for reducing backup data of a running gear which includes supplying backup data file containing auto program, then carry the auto reducing program in the running gear and reduce the data, resulting in need for installing reducing program into the target system.

Description

technical field [0001] The present invention relates to a method of restoring backup data, and more particularly to a method of restoring backup data on a mobile device such as a personal digital assistant device. Background technique [0002] In modern life, various electronic devices are often used to handle various events, such as communication, schedule management, document writing and so on. With the advancement of technology, various electronic devices are also developing towards miniaturization and are suitable for portability. A mobile device is an electronic device developed for portability, such as a personal digital assistant (PDA) and a mobile phone. The various data recorded on the electronic device are often the most important data of the user. If any accident occurs and the data recorded on the electronic device is damaged, it will cause great loss and inconvenience to the user. Therefore, frequently backing up data becomes a routine work when using electron...
