Data, the backup requirements of unstructured data.
Based on messenger service, using asynchronous framework, business interface writes data into message queue, without waiting for treatment
As a result, the influence that data backup is produced to service handling efficiency is reduced to greatest extent.Data storage is based on data file, no
Dependence and specific database platform, can both meet traditional relevant database, and the standby of NOSQL databases can be met again
Part demand.
For structural data, text is write, TLV form binary files are write for unstructured data.Can
Meet structuring, semi-structured, destructuring all types data backup demand.
Backup services read Mr. message into local temporary files, reach output data file after capacity limit.Then will
Local backup files passe is to ftp file backup servers.
The planning of ftp server data storage can be controlled according to different file types, setting time, two dimensions of capacity
System, if storage time or any dimension of capacity reach limitation, carries out rolling storage.
To improve file backup efficiency, the influence that data backup is produced to service handling efficiency is reduced to greatest extent, this
Data backup scenario, using local temporary files are first write, then by local backup files passe to ftp by the way of asynchronous
File backup server.
1 it is further described below in conjunction with the accompanying drawings, it is as follows that it implements step：
After client initiates data write request, whether business interface reads open backup switchgear distribution, if file is standby
Part switch is opening, then write data into message queue.
Backup Component service persistently reads message queue, and generation local data file is (referring to the drawings 2：Based on message queue
Backup data file product process schematic diagram).
Backup services read message queue, determine whether new information, are taken if follow-up the resuming studies of dormancy 10s without if, such as
There is new information, then read message content, call file to write interface.
File write-in interface judges whether to need to generate new file.Whether system produces newly according to write request automatic decision
File.Same table produces a data file, single file size to be no more than 1G, reach capacity limit and then produce one on the same day
Individual new file.Newly-generated temporary file is with .tmp as suffix.
If new file need not be generated, write-in file content is added.File content is write by the way of additional, is tied
Structure data write text, and the data of a row write one, unstructured data writes binary file, and file is write with TLV forms
Content, controls in the way of locking concurrently to access during individual data file write data.
4) if necessary to generation new data file, then need first to export to local directory temporary file, it is then that file is standby
Part result write-in backup document result record sheet, then generates new temporary file, writes file content.
File designation is using following rule：
The 4th section+date+major keys of table name+main frame ip：Table name-ip-yyyyMMdd-3 bit sequence numbers, such as：TRFF_
PHOTO.VIO_JDCZP-243-20161116-001.tmp。
Temporary file and data file are distinguished in the way of suffix.
Newly-generated temporary file is with .tmp as suffix.
The data file of completion is had been written into .data as suffix.
Two kinds of data recited above be locally stored catalogue planning it is as shown in the table：
Completed backup data files, write backup document result record sheet, for statistical analysis, comparing, side
Just file backup situation, server resource occupancy situation are grasped.Backup text can be quickly positioned according to stored record, during file access pattern
Part.
The backup document result record sheet is as shown in the table.
Data file is uploaded to ftp server (referring to the drawings 3 by file upload services, scan data file：It is local standby
Part files passe is to ftp server schematic flow sheet).
Upload service scans local file directory, judges whether data file (suffix is .data), if there is no
Then dormancy is continued to scan on after 10 minutes.
If there is data file to be uploaded, then ftp server storage service condition is counted, judge whether to reach storage
The upper limit.
When backup file is stored, ftp server supports that two dimensions of capacity+time are controlled, and arrives first and is defined.If appointed
One index reaches threshold value configuration, then need to delete backup file, discharges memory space.
Wherein server storage capacity limit is controlled using memory capacity control allocation list, and the file resting period uses
Storage time control allocation list is controlled, and flexibly configurable meets practical business demand.

Wherein access control list configuration example is as follows：To meet the data that structural data stores 40T, unstructured data
As a example by the scene of storage 2 years.
Memory capacity controls the allocation list to be：
Structural data acquiescence backup file type is text, and unstructured data acquiescence backup bulk-breaking type is bin.
Bin, text type are default configuration, and image-wf can split to custom-configure according to practical business, such as illegal
Image data amount can individually divide space than larger.
Capacity is not limited for empty expression.
The preferential memory capacity that accesses is not up to using the catalogue for limiting when file is stored, if being not up to the upper limit, according to
Access order is used successively from small to large.
Memory capacity is reached after SC service ceiling, need to delete file Free up Memory, and deletion strategy is to delete the earliest date
Data, once delete the data of a day.
Dynamic capacity-expanding is supported, when memory capacity control allocation list is changed, system can be perceived in time.
Storage time controls the allocation list to be：
| Backup file type | Resting period |
| text | 2 years |
If do not configured, expression is not controlled with time dimension.
Traffic table is as follows with file type mapping table：
| Table name | Backup file type |
| TRFF_PHOTO.VIO_JDCZP | image-wf |
The volume controlled that is split for practical business, it is necessary to the corresponding relation of configuration service table and backup file type, such as
Do not split, it is not necessary to configure.
Need to delete file, Free up Memory if storage cap is reached.
Support that two dimensions of capacity+time are controlled, arrive first and be defined.If any index reaches threshold value configuration, need
Backup file is deleted, memory space is discharged, realizes that data scrolling is stored.
Deletion rule：Once delete the data of a day, the preferential data for deleting the earliest date.
Upper transmitting file is to server.
Local data file is uploaded onto the server, backup document result record sheet is updated after uploading successfully, while deleting
Local file.
The planning of server storage catalogue is as shown in the table：
