Embodiment Construction

[0010] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0011] Such as figure 1 As shown, the digital camera data backup system 100 according to the preferred embodiment of the present invention includes a microprocessor controller (MCU) 10, a source memory 30, a target memory 40, a user interface 50, and a backup information generating and reading unit 60.

[0012] The MCU 10 has a built-in operating system and application software for user operation, and is used for selectively backing up the data in the source memory 30 to the target memory 40 according to the backup configuration information generated or obtained by the backup information generating and reading unit 60 middle.

[0013] The source memory 30 may adopt any suitable storage medium, and be connected to the MCU 10 through any suitable interface (for example, a conventional serial port, a parallel port, and a USB interface, etc.). The source m...

Abstract

The invention provides a data backup system and method, which comprises a source storage and a destination storage, wherein, the data backup system comprises a generating and reading unit of backup information, which is used for generating and reading backup configuration information, and leading the data backup system to selectively backup at least one part of data stored in the source storage into the destination storage. The method comprises steps which are acquiring the backup configuration information; and selectively backing up at least one part of data stored in the source storage into the destination storage according to the acquired backup configuration information. The invention can selectively backup data of the source storage into the destination storage according to user requirements, thus avoiding duplicate data existing in the destination storage device, saving storage space and reducing backup time.

Description

technical field [0001] The invention relates to a data backup device and method. The present invention relates to a device and method for a digital camera capable of backing up according to user requirements. Background technique [0002] The storage of digital photos has always been an important problem in the use of digital cameras. In order to solve the above problems, people have proposed a device called "digital camera companion", which mainly includes a card reader and a large-capacity target memory. During operation, the user only needs to insert the digital memory card supported by the card reader into it, so as to copy the digital photos on the digital memory card to the large-capacity target memory for permanent storage. The whole operation process can be completed without using a computer. [0003] However, the backup function of the current digital camera companion storage device is to back up all the content in the memory card (ie, the source memory) to a lar...
