Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following embodiments and accompanying drawings.
1. Server-side data backup and recovery
(1) Full backup and recovery (fig. 1)
Backup:
the method comprises the steps of establishing a planning task under a linux system, carrying out full backup on data at 1 point every Monday in the morning, and using a physical backup mode, namely directly copying data files and database logs from the beginning to the end of backup. And after the backup is successful, compressing the backup file and transmitting the compressed backup file to an independent backup server.
And (3) recovering:
and returning the backup file on the backup server to the database server, closing the database, deleting the original data file, decompressing the backup file, placing the decompressed backup file in a data directory, starting the database, automatically recovering the database from the data file and the log file, and finally performing account password verification and data integrity verification.
(2) Incremental backup and restore (FIG. 2)
Backup:
incremental backups are required because the volume of data is large, and the space of the backup server cannot support full daily backups. And (3) establishing a planning task under a linux system, and performing incremental backup on data at 1 point in the morning from tuesday to sunday. The method is also suitable for a physical backup mode, and the backup content is newly added data from the last backup to the current backup. And after the backup is successful, compressing the backup file and transmitting the compressed backup file to an independent backup server.
And (3) recovering:
when recovery is needed, firstly, the latest full-volume backup is recovered according to a full-volume backup recovery mode, and then incremental backups from the full-volume backup to the present are sequentially recovered on the basis. For example, if the data is lost at noon on thursday and needs to be restored, the full backup of the current monday is restored first, and then the incremental backups of tuesday and wednesday are restored in sequence.
(3) Key point backup and recovery (fig. 3)
The disadvantages of daily early morning full and incremental backups are low backup frequency and large data loss. If data loss occurs at 12 pm in a certain day, only the latest data at 1 am of the day can be recovered, and the data between 1 am and 12 pm is permanently lost. However, increasing the frequency of backups is impractical and puts a great strain on database performance and backup server capacity.
In order to make up for the disadvantage to the greatest extent, important backup needs to be performed, that is, backup with higher frequency is performed on important data, so as to reduce the loss amount of the data.
Important data of the service of the intelligent express cabinet are probably members, payment, recharging, storage and pickup records and the like, and the data are backed up once every 1 hour. The method adopts the mode of logical backup, namely exporting the data into the SQL file, and has the advantages of flexibility and capability of carrying out partial backup and recovery.
When in recovery, the full backup and the incremental backup are recovered firstly, and the key backup is recovered finally, and the maximum loss of the key data can be reduced to 1 hour.
(4) Data archiving (fig. 4)
The intelligent express cabinet service is characterized in that the passenger order price is low, but the transaction amount is large, and the flow data volume generated by transaction is very large. The flow data can account for more than 90% of the total data volume, such as access member records, recharging payment records, message sending records, verification codes, network point logs and the like. The characteristics of the pipeline data are that only insertion is carried out, modification and deletion are not carried out, the timeliness is high, and the older data is more unmanned to access.
According to the characteristics of large data volume and strong timeliness, the method adopts a filing mode to back up the running data, so that the daily backup data volume can be reduced, the total data volume of a business database can be reduced, and the query performance is improved.
The specific method comprises the steps of selecting a flow data table, establishing an archiving strategy through consultation with a service department, compiling a script, establishing a planning task, and automatically executing and sending a mail notification. For example, the accessor stream data table, the archive policy is: when the pick-up completion flag is set to 1, archiving is allowed, and the data retention period is 1 month. And the script content is used for detecting all records of the storage flow data table and filing the data which accords with the filing strategy into the filing database. The planning task was run daily at 3 am.
The filing data is stored in the filing database and can be used for historical report inquiry, such as inquiry of the transaction data volume of the last year and the whole year or the number of short message sending in a month of the previous year.
(5) For backup of archived data (FIG. 5)
As time goes on, the archive data grows continuously, putting pressure on the storage space of the archive repository. In order to solve the problem, the archive data three years ago is proposed from an archive database and stored in an operating system in a file mode, and the archive database always only stores the archive data within three years.
The filing data stored in a file mode are named by adopting a standard name and are provided with time stamps, and when the filing data need to be read, the backup files are positioned according to the time stamps and are imported into a database for report use.
2. Terminal data backup (fig. 6)
The intelligent express cabinet service is characterized by comprising a large number of express cabinets, wherein each express cabinet is provided with an independent lightweight embedded database sqlite and locally generates data. Although the data volume of a single express cabinet is not large, the data is collected to the server side to cause huge pressure on the bandwidth and influence normal business in consideration of the huge number of express cabinets. Therefore, for the scattered data distributed in each terminal, the backup mode is adopted to perform full backup once every morning, the backup files are stored locally, only the backup results (backup file names, backup time, whether backup is successful or not and the like) are sent to the server side, and once the backup fails, the server side can immediately find and give an alarm.
When the express cabinet needs to be restored, the position of the file backed up in the express cabinet system for the last time is found according to the backup result information stored in the server side, and the latest data can be restored.
In the embodiment, a multi-type and multi-dimensional parallel backup mode is adopted, the server side and the client side data of the intelligent express cabinet system are effectively backed up, the data volume, the performance influence, the timely recovery and other factors are considered, and the method has great significance for protecting the data integrity of the intelligent express cabinet system.
The above embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and any modification made on the basis of the technical solution according to the technical idea of the present invention falls within the protection scope of the present invention.
