From the synchronous corresponding backup file of all mid-side nodes of the new node；
Under normal circumstances, being divided to one-level distributed node, or be divided to three-level distributed node can meet currently
Demand of the business device to file backup；It is of course also possible to more；The embodiment of the present invention is not defined to this；
Embodiment one
As shown in Fig. 2 disclosed in the embodiment of the present invention one a kind of schematic flow sheet of file backup method；The present embodiment
By on the business device of each node device of telecom carrier-class device, pre-setting distributed file system, and in each industry
Business equipment start after, by itself centered on, automatically using itself as local node, with each node device of telecom carrier-class device
The business device of distributed file system is provided with as distributed node, carries out backing up the division of grade；The distributed document
System provide api interface, business device by api interface perform create or write file when, the distributed file system according to
File-level performs corresponding backup；
In the node device, file backup method mainly comprises the steps：
S101：Distributed file system determines the current rank for creating by api interface or writing file, if high-level
File, then be S102～S103 for the process that one-level distributed node is backed up；If low level file, then for one-level
The process that distributed node is backed up is S104～S106；
In S101, the rank of file is created or write, damage or lose produced by the safety to business device with it
Impact is directly proportional, and affects bigger, and rank is higher；High-level file includes high classified papers, high sensitive file and high reliability
File；Low level file includes：General susceptibility file, general reliability file and ordinary file；
Scene alternatively, it is also possible to be determined by distributed file system is divided to the rank of file, ordinary circumstance
Under, the file for creating under high safety scene or writing is high-level file, and the file for creating under common security scenario or writing is
Low level file；
For the backup of high-level file：
S102：The file of the establishment of distributed file system automatic synchronization or write is backed up to one-level distributed node
Storage；
The backup of high-level file needs high safety scene, therefore, in S102, directly open VW patterns, i.e., local nothing
File mode；Specially：The high-level file that local node is created or write directly is backed up into one-level distributed node
Interior, when making no presence of the high-level file on local node, and using the high-level file every time, then distributed file system is straight
Capable remote access is tapped into, the high-level file is obtained；When local node is trespassed or is destroyed, because of local reality not
There is file, therefore do not result in big loss；
Here one-level distributed node is typically chosen the business device for not opening user port；Such as existing large-scale collection
Group facility, typically has two main controlled nodes, that is, Centroid, and remaining is non-main controlled node, that is, all mid-side nodes,
It is general to detect distributed nodes at different levels from the non-main controlled node；The non-main controlled node is then general not to open user port, it is impossible to enter
The access of row external network, may only carry out network interaction with Centroid, and security is higher；
S103：Distributed file system is backed up successfully after the completion of the backup of one-level distributed node to node device feedback
Information；
In S103, once the process for creating or writing file terminates, then it is assumed that the backup on one-level distributed node
Also complete, then distributed file system then generates backup success message, point out the backup of the business device remote storage node into
Work(；
For the backup of low level file：
S104；Distributed file system is backed up the file for creating by api interface or write in local node；
In S104, local node refers to the business device set by the distributed file system, in the business device
When APP is created or write file using the api interface that distributed file system is provided, dividing in the business device is pre-set at
Cloth file system, while API is created or writes file, is backed up in local node；
That is, in this business device, outside file directory that removing itself is created or write file writes direct, should
Distributed file system simultaneously writes this document in another file directory or storage catalogue of local node, and the backup is simultaneously
Need not rely on network；
S105：The file of the establishment of distributed file system automatic synchronization or write is backed up to one-level distributed node
Storage；
In S105, when the one-level distributed node is that this business device starts, distributed text is provided with to periphery automatically
The business device of part system carries out being classified what detection was obtained；
Low level file can perform backup under common security scenario, therefore, the S105 is performed in the distributed section of one-level
The process backed up on point is：The file of the establishment or write is encrypted, is then provided using distributed file system
API write interface, the file of the establishment or write is write into one-level distributed node, stored；
It should be noted that S105 can be performed while local node is backed up S104 is performed, both do not have
Obvious priority execution sequence；
S106：Distributed file system obtains the file of the backed up in synchronization on the one-level distributed node, and saves with local
File on point is compared, if file is consistent, generates backup success message and feeds back to business device；
In order to ensure whether the backed up in synchronization on remote backup, i.e. one-level distributed node is successful, then S106 is performed, be distributed
Formula file system obtains the establishment of backup or the file of write, then using the reading interface of API from the one-level distributed node
Contrasted with the current file for creating or writing, if the file backed up on one-level distributed node is created or write with current
File is consistent, it is determined that the backed up in synchronization success on one-level distributed node；
It should be noted that for backup mode under common safe mode, it is standby on accessed one-level distributed node
Part file, can be being contrasted with the file backed up in local node；
Complete on one-level distributed node after backup for above-mentioned high-level file and low level file, based on demand,
If the distributed node for also dividing other ranks is backed up, then following step is continued executing with；
S107：Distributed file system notifies the distributed node of other ranks, synchronously should from the one-level distributed node
The file for creating or writing, is backed up；
In S107, distributed file system one-level distributed node backup success after, to two grades of distributed nodes
Synchronization message is sent with three-level distributed node, this document is obtained by two grades of distributed nodes and three-level distributed node and is deposited
Storage, completes backup；
Wherein, two grades of distributed nodes and three-level distributed node can adopt grade distributed node of async backup, i.e., two
Obtain after this document stored from one-level distributed node, three-level distributed node is obtained again from two grades of distributed nodes should
File is stored, and completes async backup；Can also be by the way of backed up in synchronization, i.e. two grades of distributed nodes and three fractions
Cloth node obtains this document from one-level distributed node and is stored simultaneously, completes backed up in synchronization；
The embodiment of the present invention need not increase any hardware, but adopt the distributed document elder generation being arranged on business device
Carry out automatic classification detection, obtain according to reliability and the hierarchical pattern for carrying out file backup of response efficiency smooth evolution, really
Protect perform file backup during reliability and response efficiency, and the number of the grade can with by node device based on need
Ask and selected；Then, different modes are selected to carry out file backup according to the height of file-level, e.g., to high-level file
By the way of the backup of VW patterns, by the way of being backed up on local node and distributed node to low level file；
And the process of whole automatic synchronization backup file is independent of the APP on node device；It follows that the embodiment of the present invention is by setting
The distributed file system being placed on business device carries out the file backup of successively hierarchical pattern, not only ensures file backup
Reliability, is also not result in that node device and the cost of telecom carrier-class device increase.
In embodiments of the present invention, based on it is above-mentioned high-level file and low level file are carried out in different ways it is standby
After part, as shown in figure 3, the local node and each distributed node to performing backup is regularly verified, noting abnormalities
When, the file based on backup is performed and read or recovery operation, and the process does not need the APP process on business device, by text
Part distributed system is voluntarily performed, and detailed process comprises the steps：
S201：Distributed file system periodically detects to local node and each distributed node, when detecting this
There is abnormal, execution S202 and S203 in ground node, when distributed node appearance is abnormal, performs S204；
S202：If occurring abnormal for local node, the file to backing up in each level node is compared, if being not less than
Backup file on the node of threshold value is consistent, then perform S203；
In S202 is performed, the span of the threshold value is not less than the 50% of the node number for performing backup；
When backup file on to each level node is compared, can be with by the way of global verification, will be whole
The backup file performed on the local node and/or distributed node of backup is compared, and judges the node with same file
Whether number is not less than threshold value；
Can also be verified for local node and part distributed node using preferred；For example, in common safety
Under scene, backup file that can be locally only on node and one-level distributed node is compared, and judges there is same file
Node number whether be not less than threshold value；Under high safety scene, the backup file on one-level distributed node is compared,
Judge whether the node number with same file is not less than threshold value；
During S202 is performed, if consistent not less than the backup file on the node of threshold value, then it is assumed that the text of backup
Part is substantially errorless；
S203：For low level file, distributed file system obtains backup file from one-level distributed node to this
File on ground node is recovered；For high-level file, distributed document is then obtaining standby from one-level distributed node
Part file performs corresponding operating；
In S203, under common security situation, if the file of local node goes wrong, the distributed document directly from
Backup file is obtained on one-level distributed node, the file on local node is recovered；
But, for the file of high safety rank, if damaging, can not be recovered, but when needs are used
Wait, directly obtained from one-level distributed node by distributed file system, by such mode, Gao An can be avoided
Full rank or high sensitive file, when local node is trespassed or is destroyed, are illegally accessed；
S204：When a certain rank distributed node occurs abnormal, distributed file system screens other distributed nodes
Replace the abnormal distributed node of the appearance；
In S204, abnormal situation occur includes：Response speed is slack-off, or breaks down；It is general to be adjusted using dynamic
The mode of grade is processed the abnormal distributed node of the appearance；
For the distributed node that response speed is slack-off, screen other distributed nodes and replace the distributed of appearance exception
The mode of node has two kinds：
First, distributed file system is degraded the slack-off distributed node of the response speed, will be original rudimentary
Other distributed node is upgraded；
Second, distributed file system directly rejects the slack-off distributed node of the response speed, to other low levels
Distributed node carry out overall upgrading；
For the distributed node for breaking down, then directly reject, entirety is carried out to other low-level distributed nodes
Upgrading；
The embodiment of the present invention, the distributed file system in business device is based on the above-mentioned local node for carrying out file backup
Regularly verified with distributed node, if exception occurs in local node, local file is carried out based on aforesaid operations extensive
Multiple, if exception occurs in distributed node, the grade of dynamic adjustment distributed node, the process of whole reparation automatically all need not
Rely on the APP in node device；Certainly, if after file is lost, it is above-mentioned that APP can actively trigger distributed file system execution
Recover the operation of file.
Carry out in the operating process of file backup, entering one based on the above-mentioned distributed file system being arranged in node device
Step, distributed file system has authentication mechanism disclosed in the embodiment of the present invention, and for the APP of the business device authority is carried out
The APP that certification, only certification pass through just can actively trigger the distributed file system and perform corresponding file backup correlation
Operation；
If distributed file system is by purview certification, confirmation currently login the user of the business device be advanced level user or
During keeper, then file backup method disclosed in the embodiments of the present invention can be performed, and to each distributed node
Management；If the user for confirming currently to login the business device is domestic consumer, it is common that the distributed file system limits this
User's establishment file, when reading file or written document, can carry out the rank of the distributed node of file backup；And, restriction is held
Deletion of the row to local file, e.g., only the user of establishment file can delete this document.
