Problems solved by technology

However, if the transmission process is transmitted from the source end to the destination end through the Internet, the following problems will occur: 1. The image files can only be received sequentially from the beginning; 2. Data is lost during the transmission process, and it needs to be transmitted again
[0008] Moreover, according to the disk storage mechanism provided by various operating systems, the storage size of the image file will also be limited.
For example, for the FAT disk storage mechanism provided by Microsoft, FAT-16 has a limit of 2GBytes for a single file, while FAT-32 has a limit of 4GByte for a single file
If the first data source on the source side exceeds the limit of its storage files, it cannot be processed as an image file

Embodiment Construction

[0039] In order to further illustrate the features and technical content of the present invention, please refer to the following detailed description and accompanying drawings of the present invention. However, the accompanying drawings are provided for reference and illustration only, and are not intended to limit the present invention.

[0040] The present invention generates corresponding image files according to the disk structure of the data source at the source end. The source end can be a personal computer, a notebook computer (notebook), a tablet computer (tablet pc) or a mobile computing device. In this embodiment, the setting source includes a data source, where the data source can be a hard disk, a redundant array of disks (RAID), or a memory card. The present invention can adjust the size of the data unit therein according to the different file storage mechanisms, so that the size of the image file of the present invention can not be affected by file systems such a...

Abstract

The invention discloses a method for generating an image file and a storage system for the image file. The image file of a data source is generated by operating the following programs through a computer. The method for generating the image file comprises the following steps: generating a first image file, setting the information of the file head of the first image file according to a plurality ofpieces of hardware parameter information of a first data source; dividing the first data source into a plurality of data units with the same capacity; if the content of currently read data units is different from that of previously read data units, recording the data units into corresponding data blocks; if the content of currently read data units is the same as that of the previously read data units, recording the sequence of the data units into the information of the first data block; establishing first file tail information used for marking the file length of the first image file.

Description

technical field [0001] A method and system for generating an image file, in particular a method and system for generating an image file with an improved data structure. Background technique [0002] For general users, installing the computer system and its application programs is a complicated matter, because the user needs to be familiar with the settings of the peripheral devices and the computer system. And it takes a lot of time to install each time, and if an error occurs, you have to reinstall it again. In order to save installation time, someone has proposed a computer system backup method. [0003] The so-called backup of the computer system refers to backing up data from the storage device of the computer system at the source, where the backup items include system information or application programs. If there is any error or damage to the computer system in the future, the user only needs to restore the backup data to the computer system, and the computer system c...
