Abstract
The invention discloses a method for backing up data in two solid state disks (SSD), comprising the steps of detecting whether data passing interfaces of two SSDs in which data are to be backed up are successfully connected and sending data to be backed up to the SSD in the case that the data passing interfaces of two SSDs are successfully connected. The embodiment of the invention also provides an SSD and a system for backing up data in the two SSDs. Because the two SSDs with direct data backup function are directly connected, data can be more easily and rapidly backed up without any other equipment and can be more rapidly transmitted between the two SSDs.
Description
Technical field
The present invention relates to technical field of memory, relate in particular to a kind of solid state hard disc data back up method, system and corresponding solid state hard disc.
Background technology
Along with the development of memory technology, the solid state hard disc (SSD, solid state disk) that adopts non-volatile flash memory (Flash) chip to constitute has appearred; Advantages such as SSD does not adopt mechanical rotation device, has the readwrite performance height, and shock resistance is strong, and the power supply expense is little are widely used in fields such as military affairs, vehicle-mounted, industry control, video monitoring, network monitoring, the network terminal, electric power, medical treatment, aviation etc., navigator.
The performance of SSD determines its utilization in the stores service of middle and high end.How to realize efficiently backing up easily, promptly realize that directly backup is the direction of a technical development not influencing under current stores service duty and the server architecture situation as far as possible.
The normal mode that adopts of existing backup mode has the rear end of increasing connection device to back up and does redundancy backup in the mode of disk array.The backup mode that increases the rear end connection device often adopts interpolation tape or hard disk data to be backed up or use network building-out store (NAS, Network Attach Storage) is storage area network frameworks such as (SAN, Storage Area Network) transmission data backup.The disk array method can according to the different shape of array do redundancy backup or the compression after redundancy backup.When needs backed up a hard disc data separately, a kind of mode was: two hard disks are articulated on the same main frame, by the copying data between two hard disks of main frame realization; Another mode is to come realizing the transmission of data between hard disk by special equipment " disk copy machine ".
In research and practice process to prior art, the present inventor finds, the backup method complexity height of prior art, and the input cost height, the copying data between hard disk is slow.
Summary of the invention
The embodiment of the invention provides solid state hard disc data back up method and system and corresponding solid state hard disc.
A kind of solid state hard disc data back up method comprises:
Detect to be equipped with dish by whether successful connection of data-interface;
