Operation and the security of online data.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Accompanying drawing 1 is the principle schematic of a kind of server data online backup method of real-time mirror image.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
HeartBeat, heartbeat monitoring；EterneDisk disks, mirrored disk volume.The present invention is a kind of clothes of real-time mirror image
Business device online data backup method.
Embodiment 1：
A kind of server data online backup method of real-time mirror image, in the Dual Computers Cluster System based on shared disk array pattern
In, major-minor Disk Backup and equity are realized by backup software, to realize the online backup of server data.Specific steps are such as
Under：
S1, by the respective connection server of two disk arrays, two-server is respectively mounted backup software, to cause every service
The two disk arrays can be accessed on device；
S2, using the image feature of backup software two described disk arrays are combined as mirrored disk volume, form magnetic
Disk pair, to ensure that two disk array disk data are completely the same；Two disk sheets are ensured by mirrored disk volume（Disk point
Area）On data it is completely the same.
S3, configuration service application monitoring, provide the resource in heartbeat monitors environment, for ensureing it by backup software
Business runs without interruption.
Described service application monitoring, abbreviation SSM refers to the monitoring and optimization to Mission critical applications, and improving business should
Availability and reliability index, reduce the input and workload of O＆M, and the conventional service application monitoring system in the country has wave
Damp SSM.Major function monitors two kinds of monitoring patterns with long-range to provide server agent Agent monitorings without agency；Intelligent early-warning
With effective alarm；Supported by providing Templated configuration for monitoring configuration, alarm configuration, form configuration etc., help data
Care workers realize quick Report Customization etc..Product architecture includes data collection layer, data analysis layer, business module
Layer, function represent layer.
Two-server is realized by heartbeat and is connected with each other.Resource in described heartbeat monitors environment, including thing
Manage volume, virtual address, database, the monitoring resource and switch operating of program application.Heartbeat mainly utilizes a RS-233 inspection
Surveyor's chain road is completed, and detects the accuracy of checking system Down machine testings using Ping modes.
Described two-server, each includes four pieces of network interface cards.Four pieces of described network interface cards, including one piece of network interface card are used to carry
ISCSI data flow, one piece of network interface card is used to do public network network interface card, and two pieces of network interface cards are connected for private network.
Wherein, ISCSI, that is, represent Internet SCSI (small computer system interface) abbreviation, as passing through
TCP/IP networks efficiently transmit the new agreement of data between different pieces of information storage device.As a rule, ISCSI is for from institute
The SCSI data transfer initiators of meaning transmit the end-to-end protocol of data storage to scsi target side；Described target, which is put, rings
Should be in the scsi device for the request for carrying out I/O processing, described initiator is the SCSI for starting input/output-I/O-processing
Equipment, such as application server, or the simply personal computer-PC-or work station of user, such as storage device；Wherein
SCSI initiators and scsi target side are both connected to TCP/IP networks.
ISCSI agreements be using message semantics with by block-oriented data storage SCSI protocol be mapped as TCP/IP association
SCSI transportation protocols, it uses the form of byte stream, it is possible thereby to transmit scsi command by TCP/IP networks：General SCSI lives
Description block (CDB) is made to be encapsulated in ISCSI data cells, it is referred to as packet or protocol Data Unit (PDU), then
Before desired object scsi target side is sent it to by network, it is sent to TCP layer and (and similarly, is come from
The response of the scsi target side is encapsulated in ISCSI PDU, and is forwarded to TCP layer to send initiator to by network
SCSI promoters).
Described backup software mainly possesses data backup, recovery capability, and data recovery element supports cloud computing, virtually
Machine is protected, and is met and is pressed cycle full dose and incremental backup, it is ensured that data safety.Backup software selected by the present invention, to possess mirror
As the backup software of function, such as tide backup software.
Two described disk arrays are two completely reciprocity, and the equal disk sheet of capacity or disk partition are described
Mirrored disk volume is applied to business main frame, and any modification of the business main frame to described mirrored disk volume writes two simultaneously
On disk array.
A kind of server data online backup method that the present invention passes through real-time mirror image, it is ensured that core information system should be accessed
Uninterrupted operation and online data security, so as to improve the competitiveness of data center and server storage product.
It should be understood that, although this specification is been described by according to embodiment, but not each embodiment only includes one
Individual independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art will should say
Bright book is as an entirety, and the technical scheme in each embodiment may also be suitably combined to form those skilled in the art can
With the other embodiment of understanding.
By embodiment above, the those skilled in the art can readily realize the present invention.But should
Work as understanding, the present invention is not limited to above-mentioned several embodiments.On the basis of disclosed embodiment, the technology
The technical staff in field can be combined different technical characteristics, so as to realize difference.
