[0002] Network data backup has always been an important means of network data sharing and network data security. In the environment where the internal and external networks are physically isolated, the network gateway is usually used for data replication. When data needs to be copied between the two networks, manual Operate the storage medium for forwarding; before forwarding, that is, before the network "writes" the original data into the physical isolation gatekeeper, it is necessary to perform a security check on the original data to ensure that there are no virus codes, malicious attack codes, etc.; at the same time, this This kind of copying process, there is also the hidden danger of data exposure when the physical isolation gatekeeper connects incorrectly
However, image file storage requires manual operation, and manually operated image files also have defects in data security and data accuracy.

Embodiment Construction
[0016] The system framework for realizing the method of the present invention adopts general javabeans, assuming that the first network is an internal network, and the second network is an external network. Initiating automatic replication can be achieved by running a program. In this program, you can set the source directory / folder and the target directory / folder, both of which are located on two servers or terminals on the internal and external networks, and you can also set the time interval for automatic replication.
[0017] In order to realize the association between the user name and password and the automatically copied files, the user name and password are obtained through the ie connection of the internal and external networks, and then the downloaded files and uploaded files are downloaded and uploaded through the authority of the user name and password . When automatic data replication is started and running, the protocol used to transmit data between the two appl...

This invention discloses a method for automatically duplicating data between a first and a second networks separated by physical isolation including the following steps: 1, obtaining the user names and ciphered codes on the two networks to get the source and target of duplicated data and time interval of automatic test and duplication and carrying out the following steps in space:1, reading the source data to a temporary catalog from the first or the second network, 2, carrying out criterion and compressed ciphering to the data, 3, sending the ciphered data to the second or the first network.Advantage: 1, dynamically refreshing data to keep them consistent without being transmitted by storage medium, 2, not needing the test of virus, 3, returning back to the original state even if error connection appears, 4, no file marks are left during the automatic duplication to ensure the safety of software and data, 5, manual work is not necessary.
