The invention discloses a solid-state disk and a data processing method and system thereof. The method comprises the following steps of: detecting an operation, for a first storage area visible to anoperation system, of a user on the solid-state disk; if the operation is a reading / writing operation, keeping data synchronization between the first storage area and a mirror image data storage area of a second storage area invisible to the operation system on the solid-state disk; and if the operation is a deletion operation or a TRIM operation, keeping data synchronization between the first storage area and the mirror image data storage area of the second storage area, and backing up data deleted from the first storage area to a deleted data storage area of the second storage area. Through the second storage area invisible to the operation system, the problem that data cannot be recovered due to malicious data deletion or wrong operation can be avoided, and by utilizing a flash memory controller, data backup and recovery can be carried out on data in the solid-state disk.

The invention discloses a hard disk data backup and restoring method, a system and a computer; the hard disk data backup and restoring method comprises the following steps: on a virtual machine manager layer, weather write operation of at least one operation system which is operated on the virtual machine manager layer is carried out to a hard disk port is monitored, when the write operation is monitored to be carried out, a sector number of a target sector, corresponding to the write operation, is recorded; according to the sector number, the data in the sector is backed up, and the backup is that the data in the sector is stored in a protective subarea; in addition, the current time point is used as a first identification of a first time point; according to the first identification, the backup data at the first time point and the backup data before the first time point are restored to the corresponding sector, and the backup data before the first time point comprises original backup data.

The invention relates to a power metering method of an electric energy meter. By introducing a CRC check and a data backup mechanism, a backup area is set correspondingly for each main area divided into the power RAM area, and a backup area is also set for the main EEPROM area of ​​the EEPROM area. In the EEPROM area, data backup is realized to avoid the loss of the original energy data stored in the main area; after the energy meter is powered on, after the anti-fly away processing mechanism is executed for the read energy data, and the power failure of the energy meter is detected The CRC verification process is performed every time, so as to ensure that the power data before entering the next step is the normal power data that has passed the CRC verification, so as to ensure that the subsequent measured power is accurate; and for the power that has not passed the CRC verification The data introduces an error correction mechanism, that is, uses the power data in the backup area to update the power data in the corresponding main area to ensure that the power data in the main area is correct.

The invention relates to an intelligent multichannel fiber bragg grating (FBG) online backup system, which comprises an upper computer, an FBG signal processor host, an FBG signal processor standby machine, a hot spare switch module and a sensor module, wherein the sensor module is connected with the hot spare switch module through a transmission cable, the hot spare switch module is connected with the FBG signal processor host and the FBG signal processor standby machine through optical cables, the FBG signal processor host and the FBG signal processor standby machine are respectively connected with the upper computer so as to transmit a demodulation signal, and the hot spare switch module is connected with and controlled by the upper computer. The intelligent multichannel FBG online backup system adopts two sets of system hot engine backup and can realize automatic intelligent switch, thus being convenient for use and having high reliability.

The invention provides a data backup method and electronic equipment. The data backup method is applied to the electronic equipment. The electronic equipment comprises a nonvolatile memory. The data backup method comprises the steps that data are written into the nonvolatile memory; snapshots of the data are established, and the data, corresponding to the snapshots, serves as a protected area which cannot be rewritten; a current mapping table is copied, and corresponding relations of physical addresses of the data corresponding to the snapshots in the nonvolatile memory and logical addresses of the data are established in the mapping table; the mapping table which serves as an initial mapping table is stored into a particular area of the nonvolatile memory.

The invention relates to the technical field of computer communication, in particular to a backup method and a backup device, aiming to reduce redundant data in a communication device and reduce production cost of the communication device. The method comprises the following steps of identifying whether service integrated circuit boards are inserted into both slots respectively corresponding to a main slot identification and a paired secondary slot identification according to the paired main slot identification and secondary slot identification stored in configuration information, wherein the main slot identification is used for uniquely identifying the slot a main service integrated circuit board to insert, and the secondary slot identification is used for uniquely identifying the slot allowing a spare service integrated circuit board to insert; if so, pointing the data finger of the spare service integrated circuit board inserted in the slot corresponding to the secondary slot identification to the storage position of the data content of the main service integrated circuit board inserted in the slot corresponding to the paired main slot identification. Thus, with the adoption of the method, the redundant data in the communication device can be reduced, and the production cost of the communication device can be reduced.
