Description
Technical field
The present invention relates to computer data backup technical field, more particularly, to a kind of LAN-free standby systems.
Background technology
In information technology and data management field, redundancy technique is by file system, database or other production servers
The data of application are replicated and are saved in the storage of specific media services management, once production server occur disaster or
During faulty operation, from the media services after backup data recovery in storage, original production server can be made to recover normal
Operation.
Traditional redundancy technique is backed up by LAN, that is, the data backed up are by ethernet stream to media services management
In storage.The efficiency of this backup mode can be influenceed by the intrinsic higher network delay of Ethernet and computing resource, simultaneously
Also Backup Data is made to occupy the network bandwidth of production server work.
It is widely available with storage area network (SAN) equipment, more and more specific data-management applications and corresponding
The solution of hardware uses in SAN infrastructure.Realize that LAN-free backups are increasingly becoming a kind of trend.SAN is usually
Data are transmitted using FC (Fibre Channel) agreement.LAN-free backups are by SAN, will produce the number of server application
According to backuping in the storage that media services are managed.Backed up relative to traditional LAN, so SAN height can be made full use of to gulp down
Tell, low time delay the advantages that.
Traditional LAN-free backup scenarios be the client software of backup and media services module are all deployed in it is same
On platform production server, write data into by way of shared drive in the storage device of media services management.This backup
Mode can make that any change of standby system is impacted to business and autgmentability is restricted.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind can solve backup window
Mouth problems of too, the flexible configuration for realizing medium module and dynamic adjust, are easy to the LAN-free standby systems of integration.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of LAN-free standby systems, including main control service module, media services module and backup client end module,
The backup client end module is installed in production server, and the media services module is installed on one independently of production server
In backup server, the backup server connects production server by FC interchangers with Ethernet switch respectively, wherein,
Main control service module, initiated by LAN and terminate backup or recovery tasks；
Backup client end module, after the backup tasks order of main control service module is received, required data are sealed
Dress up and media services module is transferred to by SAN after regulation data block format, appoint in the recovery for receiving main control service module
After business order, receive in the data block write-in client storage from media services module；
Media services module, in backup procedure, the data block of backup client end module is received, and parse and write after converting
Enter in backup storage, in recovery process, take out corresponding data object in being stored according to recovery time point from backup, be packaged into
Backup client end module is sent to by SAN after data block.
The HBA cards for supporting FC agreements are equipped with the backup server and production server.
The media services module includes：
FC frames receive and dispatch layer, are responsible for response HBA cards and interrupt and be packaged and decapsulate after receiving FC frames from buffer queue
Processing；
SCSI subsystem layers, it is responsible for being abstracted block device in systems；
SCSI Target layers, by media services module abstracts into destination end and can be with backup client end module
Initiator ends are established and connected end to end；
IO receives and dispatches layer, establishes internal memory mapping relations with upper layer application, receives and dispatches I/O event；
LAN-free service processes, according to the I/O event received, read-write mapping region of memory and by corresponding block I/O operation
It is converted into the write-in backup storage of object I/O operation, while SCSI Target layers is managed.
The backup is stored as the object storage that there is time dot format to deposit.
The main control service module and media services module are installed in a backup server jointly, or independently of medium
Service module is installed in another backup server.
The backup client end module includes：
Data source information unit, the control instruction of main control service module is responded, to the number respectively applied on production server
Browsed and managed according to source information, including deploy directory tree, the database application situation of file system in the case of file system
The table structure in lower expanding data storehouse etc..
The main control service module includes：
HBA card control units, management and configuration HBA cards, while monitor the operation transmission state of HBA cards.
The backup server is at least provided with one.
The production server is at least provided with one.
The standby system also includes disk array, is connected with FC interchangers.
Compared with prior art, the present invention has advantages below：
1st, handled up using SAN height, low time delay the characteristics of, solve when client backup data volume it is very big when, cause to back up
The problem of window is excessive, so as to meet the backup requirements of various applications.
2nd, the deployment of media services module is isolated with production server, and the flexible configuration and dynamic for realizing medium module are adjusted
It is whole, it is therefore prevented that the replacing of medium apparatus and have impact on production server application normal operation.
3rd, by the quantity of server where accordingly increasing or reducing media services module, backup can dynamically be extended
System, so as to meet the requirement such as the stability of standby system and High Availabitity.
4th, more equipment can be supported to realize LAN-free backup scenarios.Such as physical tape storehouse, ordinary magnetic disc and backup
All-in-one etc..
5th, the last present invention is also easily mutually compatible with the backup scenario of existing backup all-in-one standalone media service module, from
And it is easily achieved integration.
