Problems solved by technology

At present, the security measures for the system disk mainly adopt these two schemes. The first scheme is to do disk mirroring on the system disk. Disk mirroring is also called RAID 1, where RAID is the abbreviation of Redundant Array of Independent Disk, which means independent redundant disk array. Disk mirroring can ensure that the hardware failure of one of the system disks will not cause damage to the system by mirroring the data of one disk to another disk, and can ensure the reliability and repairability of the system to the greatest extent without affecting performance. It has a high data redundancy capability, but the disk utilization rate is 50%, so the cost is high, 3 and this solution cannot guarantee the failu

Embodiment 1

[0021] A data backup method using dual hard disk read and write operations, comprising the following steps:

[0022] 1. Set up the hard disk: there are two hard disks, and the hard disks are all electronic hard disks with independent power supply of Serial Advanced Technology Attachment (Serial Advanced Technology Attachment, referred to as SATA) interface (DOM disk, also known as DOM electronic hard disk, DOM is Disk On The abbreviation of Module, DOM electronic hard disk adopts Flash On Disk technology, which is a fast memory storage media component with high performance and high stability), one of the hard disks is used as the main disk, and the other hard disk is used as the backup disk, the main disk, the backup disk and the The internal memory is connected to the central processing unit through a signal line, and linux is selected as the operating system of the network storage in this embodiment.

[0023] 2. Hard disk partition: Divide the space of the main disk into thr...

Abstract

The invention relates to the field of methods for processing electrical and digital data which are accessed, addressed or distributed in memory systems or architectures, and in particular relates to a method for backuping data through adopting dual-disk read-write operation. The method for backuping data through adopting dual-disk read-write operation comprises hard disk arrangement, and is characterized by further comprising the following steps of a, hard disk partition; b, master disk initiation; and c, standby disk initiation. The method has the advantages of high safety, strong reliability, quick operation speed, shortened system breakdown time and convenience in maintenance.

Description

technical field [0001] The invention relates to the field of electric digital data processing methods for accessing, addressing or distributing in a memory system or architecture, in particular to a data backup method using dual hard disks for reading and writing operations. Background technique [0002] With the advent of the information age, data has grown explosively, and 80% of these data are unstructured data. With the increasing popularity and deepening of computer and network applications, the network has become the best medium for storing these data. Using the network to store data requires installing system software on the network system disk and making corresponding user configurations. Therefore, ensuring the security and rapid recovery of data in the system disk is of great significance to improving the high availability of network storage itself. At present, the security measures for the system disk mainly adopt these two schemes. The first scheme is to do disk ...
