Description

Real-time automated back-up hard-disk system

Technical field

The utility model belongs to a kind of real-time automated back-up hard-disk system, be mainly used in the computer system, it can back up by the autokinetic system dish by a back-up disk, utilize mapping/reconstruction (MIRROR/REBUILD) principle of standard to do to use with mounting structure on use, and then the work that reaches moves, at any time by the back-up disk automated back-up, economy that tool is preferable and ease of use.

Background technology

Data backup is for the computer user, be a very important job, traditional method is to back up with disk or CD, but, problems such as access speed slow, difficult preservation little because of its capacity, rare people uses, and mode time is come storage data with hard disk as backup tool exactly at present, use hard disk to carry out data backup, following method generally arranged:

One, utilize the method for disk copy, directly the content replication of source tray in the future is to the purpose dish, can select the direct copy of two hard disks in this method to hard disk, or use archives that the correspondence of archives is copied, its method is the simplest, but need with manpower regularly, regularly or one by one the copies data of source tray from the beginning of archives copy to the purpose dish, remove labor intensive, time, also there is omission in regular meeting because of user's carelessness; In addition, during hard disk, bigger as hard-disk capacity as copy, the more then the time of cost also the more and then influences user's operating efficiency to archives relatively.

Be to be the progressive mode of backing up in realtime two,, this mode mainly is to be that the overall hardware unit that is provided with of independent system is as the control platform in the computer host system, this hardware unit connects two hard disks, first is that scratch diskette, second are back-up disk, when the host computer end to first scratch diskette more during new data, simultaneously also to second new data more, therefore at any time, the content of these two hard disks all is the same.The defective of aforesaid way maximum is exactly the user is the needs of backup, and must purchase two hard disks simultaneously comes system backup, and therefore the economy of using is not good, and its cost that increases on foot also is a burden greatly to the user.

The utility model content

Fundamental purpose of the present utility model, provide a kind of real-time automated back-up hard-disk system, wherein the bridge joint control module links by system transmissions interface and central processing unit, and have two connectivity ports and link with system disk and back-up disk respectively, central processing unit is carried out computer system work operation, the backup careless omission of also avoiding human factor and being caused, and then simplify the hard disk backup operation and promote data and save usefulness from damage.

Secondary objective of the present utility model, provide a kind of real-time automated back-up hard-disk system, wherein the utility model utilizes a back-up disk just can move the backup of computer system hard disk certainly, and it is not restricted to the backup of two hard disks, and, also can satisfy the excellent economy of tool with respect to the backup between the different cut sections of another hard disk.

A purpose more of the present utility model, provide a kind of real-time automated back-up hard-disk system, wherein the utility model is assisted without any need for software or program, do not need simultaneously any setting or initialization, as long as the utility model and computer system are linked, the bridge joint control module can be by mapping or the technology of rebuilding, backed up in real time or rebuild by back-up disk, therefore quite simple and easy on using, and do not have other special requirements, peerless good convenience of tool and compatibility to environment or spare part are set yet.

Another purpose of the present utility model, provide a kind of real-time automated back-up hard-disk system, wherein hard disc module comprises system disk and back-up disk, one of them damage when two hard disks, bridge joint control module another hard disk that can automatically switch works on, and during the replacement hard disk, be automatically new hard disk to be done backup and rebuild; The bridge joint control module is connected with a demonstration and an alarm module in addition, remove in its state of explicit declaration just often, any one takes place to send caution with the cresset or the sound when unusual in system disk or back-up disk, is to save effect from damage the utlity model has good performance performance and oneself.

Embodiment

See also shown in Figure 1ly, be the real-time automated back-up hard-disk system of the utility model, comprise the central processing unit of being located on the motherboard (figure does not show) 10, and the system transmissions interface 20 of connection central processing unit 10 and bridge joint control module 21; Bridge pier connects control module 21, further has the connectivity port of two branches, and one is system disk connectivity port 22, and another is back-up disk connectivity port 23; And bridge joint control module 21 is connected with a demonstration and an alarm module 24; Hard disc module comprises system disk 31 and back-up disk 32, is linked with bridge joint control module 21 by system disk connectivity port 22, back-up disk connectivity port 23 respectively, and central processing unit 10 is carried out computer system work operation, is backed up in real time or is rebuild by back-up disk 32.

By above-mentioned feature, the utility model can be connected (seeing also Fig. 2) by system transmissions interface 20 (as IDE, SATA or scsi interface) with motherboard, during system boot, bridge joint control module 21 is a connected system dish 31, and whether check system dish 31 is normal, unusual as system disk 31, then show its states, and please whether damage by user's check system dish 31 by demonstration and alarm module 24; When system disk 31 is normally promptly set writing system dish 31 for coming source tray (Sources Flag), and detect back-up disk 32 simultaneously,,, and alarm with the light or the sound promptly by showing and alarm module 24 shows if back-up disk 32 has unusually; And central processing unit 10 is carried out computer system work operation, bridge joint control module 21 is detection system dish 31 and back-up disk 32 data difference each other at any time, and application mapping (MIRROR) technology control back-up disk 32 real-time automated back-ups are also feedback and are given bridge joint control module 21, reach the usefulness that is got final product automated back-up or reconstruction by a back-up disk 32.
