Abstract

The present invention discloses a safe data storing method. By connecting with a plurality of storage device, the computer system can store any one data into two separate storage devices simultaneously to form a relationship; when the data in one of the storage device is damaged, or the storage device is damaged, the present invention can take out the data from the other storage device which stores the corresponding data and stores the data into other storage device, to guarantee that any one of the data has usable data in two storage devices simultaneously. When reading data from the two storage devices, the present method can select one, and when one storage device storing the data is damaged, the method can read data from the other storage device. The present invention has low cost, strong data safety and strong expansibility, can increase or decrease the capacity of the storage device at will, and is applicable to the storage system formed by multi hard disks and multiserver, and has high data read rate. No recreating time is needed, when finding data damaged during the course of data reading, the present method can retrieve on line, without influence for the data reading and running.

Description

technical field

[0001] The invention relates to a data safe storage method, in particular to a data safe storage method based on multiple storage devices, which can realize real-time backup and online recovery of data, and ensure the safety of stored data.

[0002] In particular, it provides a data security storage method used in a storage system on a TV station video server. Background technique

[0003] The safe storage of data is a very important task, especially for some special industries, the safety, reliability, and stability of data storage even exceed the requirements for functionality, and even require that damaged data can be recovered in the shortest possible time. Recovery, in order to realize the timely reading of data and ensure that the work performed by the computer system is not interrupted. For example, the storage device used for the video server of a TV station is required to ensure that the stored program data is safe and reliable, and even if the data...

Embodiment Construction

[0051] The basic idea of ​​the present invention is to adopt distributed real-time backup storage, and trade space for safety. Access multiple storage devices in any known way in the computer system, and store any data in two different storage devices at the same time. When the data in a certain storage device is damaged, or the storage device is damaged, the corresponding Other storage devices for data take out data and store them in other storage devices, so as to ensure that any data has available data in the two storage devices at the same time. When reading data, read from one of the two storage devices. If a storage device storing data is damaged, read data directly from the other storage device.

[0052] In order to facilitate the understanding of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0053] The hardware structure provided in Fig. 1 and Fig. 2 is the same a...
