Problems solved by technology

But with a file server, the parallel SCSI bus that connects the server to the storage disks has some physical complexity, and the setup of parallel wiring, host bus adapters, and terminations as part of a file server deployment can be cumbersome
In addition, the delay caused by the low speed of file server hardware and different operating systems also brings obstacles to data backup

Embodiment Construction

[0019] figure 1 An embodiment of the invention is shown, including a backup server and a client. In digital home applications, the backup server is placed on the Internet and has an independent IP address. Such as figure 1 As shown, both the backup server and the client have a file system, a hard disk drive module and a network interface card, and are connected to the Internet through the network interface card, and then connected to each other through the Internet. The backup server is configured with a SCSI card for connecting to the TCP / IP network, storing and transmitting SCSI commands and data. The hard disk drive module of the backup server is SCSI.

[0020] Such as figure 1 As shown, between the file system in the backup server, the hard disk drive module, and the network interface card, information transmission between the interfaces is also provided to realize communication, and the data of the NIC network interface is directly written / read to the SCSI hardware in...

Abstract

The invention discloses a system which can realize the real-time data backup in the digital home network, including the backup server and client, the backup server and client include the file system, hard disk driving module and network interface card, and are connected to the network via the network interface card; in addition, the backup server end also includes the SCSI-NIC device driving module used for the information transfer between the interfaces. The SCSI-NIC device driving module is set between the file system and hard disk driving module and network interface card; the backup server is configured for the SCSI card which connects the TCP.IP network, store and transfer SCSI instructions and data; the hard disk driving module of the backup server is SCSI. The storage technology is combined with the iSCSI technology in the invention, is applicable to different operating system, can process the request from different systems in the network, and back up the data in time and effectively, simplify the operation of the data backup, and further improves the use effect and application of the data backup.

Description

technical field [0001] The invention relates to a computer data storage technology, in particular to a system for realizing real-time data backup in a digital home network. Background technique [0002] Data is an intangible asset. In many fields, data is a much more valuable asset than computer hardware equipment. No matter what happens, such as hacker attack, power failure, fire, etc., it is required to ensure that data will not be lost, so data backup is very important. At the same time, with the rapid popularization and development of computer applications, the importance of data backup in daily work and life has become increasingly prominent and deeply rooted in the hearts of the people. The traditional data backup method is just to copy the daily business records in the form of files, or save them in another machine device. However, for home users, this kind of daily data backup work is very cumbersome. On the other hand, because these data copies cannot leave histor...
