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 present invention provides a system backup and recovery device suitable for a system on chip, which includes a system on chip chip, a first memory, and peripherals to be backed up and / or restored; the first memory and the peripherals are all electrically connected to the system on chip; The first memory is used to store BIOS data and system image data; the system-on-chip chip includes a processor, a second memory, and a peripheral interface module; the processor is used to read the system image data from the first memory, and write the system image data Peripherals; the second memory is used to store system image backup control files; the peripheral interface module is used to control the communication between the SoC chip and the first memory, peripherals and serial ports. The invention also provides a system backup and recovery method suitable for the system on chip.

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.

The invention relates to a multi-point centralized remote backup disaster recovery technology and system based on Ethernet streamlined transmission, and relates to the technical field of data disaster recovery. On the one hand, it provides a multi-point centralized remote backup disaster recovery technology based on Ethernet streamlined transmission, including obtaining user data and analyzing it, determining the size of the data according to the analysis results, and selecting priority transmission or priority classification and block selection according to the size of the data The completed data is compressed and encrypted, and the encrypted data is backed up once and stored in any other end server; on the other hand, it provides a multi-point centralized remote backup disaster recovery system based on Ethernet streamlined transmission, including end servers including data acquisition units, The analysis unit, the second classification unit, the second block unit, the transmission unit and the storage unit, and the node server include a receiving unit, a first classification unit, a first block unit, a compression unit, an encryption unit, an association unit and a backup unit, Improved protection of user data.

The invention discloses a high-speed data backup method under a samba server cluster, which comprises the following steps of: performing initial data backup on a storage device A through a backup device B in advance; waiting for the data backup operation to be activated, requesting to acquire a difference file list to each samba server node when the data backup operation is activated, wherein thedifference file list comprises target file information of the samba service request initiated by the client intercepted by the samba server node under the samba server cluster; merging all the difference file lists; and performing data differential backup on the storage device A by the backup device B based on the merged difference file list. The high-speed data backup method under samba server cluster can solve the problem of low incremental backup efficiency and over high occupied resource in samba server cluster environment, and has the advantages of high backup efficiency, fast backup speed and low occupied resource.

The invention discloses a data backup method of a solid-state hard disk, which includes: detecting whether a backup disk is successfully connected through a data interface; and sending backup data to the backup disk when the connection is successful. The embodiment of the present invention also provides a corresponding system and a solid-state hard disk. Because the technical solution of the present invention adopts the structure method of SSD with direct backup function, two SSDs are directly connected, data backup becomes simpler, without the help of other devices, data transmission between hard disks is faster, and the backup speed is faster.
