Data check backup, writing and reading method among multiple groups of storage devices

Abstract

The invention discloses a data check backup, writing and reading method among multiple groups of storage devices. A magnetic random access memory, a solid state disk and a flash card are arranged among the multiple groups of the storage devices. The method comprises the following steps of S1, reading data information of the magnetic random access memory; S2, verifying a check value; S3, backing upthe data information in the solid state disk and the flash card; S4, writing original information into the solid state disk; S5, encrypting the information written into the solid state disk; S6, writing the original information into the flash card; S7, reading backup data in the flash card; and S8, reading the backup information of the solid state disk. According to the data check backup, writingand reading method among the multiple groups of the storage devices, the magnetic random access memory is adopted; the expansibility of the memory is improved; the service life of a battery can be prolonged; the accuracy of data backup is improved; the backup time is shortened; and the data security is improved.

Description

technical field [0001] The invention relates to the field of storage devices, in particular to a data verification backup, writing and reading method between multiple groups of storage devices. Background technique [0002] The storage device is an important part of the computer system. It has developed rapidly in recent years. Disks and tapes have always been the main storage devices of computers. Disks are divided into hard disks and floppy disks. The access speed of hard disks is much higher than that of floppy disks; the existing multi-group The methods of data verification backup, writing and reading between storage devices are not perfect, and magnetic random access memory is not used. Many ordinary memories cannot be erased and written infinitely, and the scalability of ordinary memories is very limited, requiring power-on It can keep the data state, which will reduce the life of the battery, and does not use a more convenient data verification method, which increases...

[0002] The storage device is an important part of the computer system. It has developed rapidly in recent years. Disks and tapes have always been the main storage devices of computers. Disks are divided into hard disks and floppy disks. The access speed of hard disks is much higher than that of floppy disks; the existing multi-group The methods of data verification backup, writing and reading between storage devices are not perfect, and magnetic random access memory is not used. Many ordinary memories cannot be erased and written infinitely, and the scalability of ordinary memories is very limited, requiring power-on It can keep the data state, which will reduce the life of the battery, and does not use a more convenient data verification method, which increases the time required for backup, and also reduces the accuracy of data backup. It does not use encrypted writing, which is safe Sex is not high enough
