The invention discloses a database backup method and device. Data tables in a database are classified into historical data tables and real-time service data tables; full-volume backup is conducted on the service data tables; incremental backup is conducted on the historical data tables; the backed-up service data tables and historical data tables are stored in a medium to complete backup of the database. Due to the fact that historical data in a large mysql database occupies a large amount of storage space and real-time service data is less, the historical data tables and the real-time service data tables are backed up in a separated mode, the data volume each time of backup can be decreased, the backup time and recovery time can be shortened, and the backup speed can be improved. It is thus clear that backup of the database in a large mysql database scene is rapidly achieved, the backup recovery time is decreased, backup file space occupation is decreased, and the backup recovery efficiency and the safety guarantee capability of the database are improved.

The invention discloses a data backup method and a data backup device, aiming at solving the problems that in the prior art, data backup is slower in speed and lower in accuracy. The method comprises the steps of aiming at an event to be dealt with, confirming a table identity (ID) and a sub-library ID corresponding to the table ID which are contained by the event to be dealt with; judging whether the assigned event which is in conflict with the event to be dealt with exists or not at present; if yes, assigning an event to be assigned into a waiting queue where the conflicting assigned event is positioned, and waiting for processing; if not, selecting one in waiting queues of all threads, and assigning the event to be assigned into the selected waiting queue, and waiting for processing. The method is used for dealing with the multiple events which are not in conflict with one another by arranging the multiple threads in parallel, and all the operating record contained in one event can be processed by one thread, so that the backup speed of a backup library can be effectively accelerated, the processing consistency of all the operating record contained in the same event can be guaranteed, and the event dealing accuracy of the backup library is improved.

The invention relates to a method for mounting a backup virtual machine based on an nfs volume. The medium on a medium server is made into the nfs volume and mounted on a virtualization platform, then, a magnetic disk of the virtual machine and configuration files of the virtual machine are copied to the nfs volume mounted through the medium server, and the nfs volume of the medium server is uninstalled from the virtualization platform after the magnetic disk and the configuration files of the virtual machine are copied. Compared with the prior art, the method for mounting the backup virtual machine based on the nfs volume has the advantages that the backup speed of the virtual machine can be multiplied, and thus the backup time is shortened.

The invention discloses an efficient file backup and recovery method. The technical problem to be solved is to change the traditional backup method under the premise of normal system operation, speed up file backup or recovery and save storage space. Can accurately and efficiently restore the required files. Technical solution: As time goes by, the change of the file leads to a new file version. The new version can be formed by combining the change data of the file with the previous file version. When saving the change data of the file, it can be divided into continuous storage blocks and stored in In the medium, if the data of the storage block is the same as that of an existing storage block, it does not need to be stored repeatedly. The memory assigns a unique ID to the storage block, and the recovery file operation is realized through the collection of these IDs. The present invention does not need to repeatedly store the same data block, saving storage space; it does not need to perform operations such as data copying and pasting, and improves recovery speed and efficiency.

The present invention relates to the technical field of backup and restoration of databases, in particular to a hot backup method for MySQL databases, comprising: when the backup starts, first checking the log sequence number of the MySQL database, and then backing up the data files of the MySQL database; During the process, the redo log of the MySQL database is checked cyclically at the same time, and the modification of the data file is backed up during the backup process. The log sequence number in the redo log is greater than the log sequence number at the beginning of the backup. The log is recorded in a file and stored in the shared storage Device; after the backup is completed, record the log sequence number at this time to prepare for the next backup. The invention also provides a hot backup system of MySQL database. Compared with the prior art, the technical scheme of the present invention has fast backup speed and fast recovery speed, overcomes the shortcoming that the MySQL database must be stopped before backup, and has less impact on the MySQL database business.
