在Linux USB的gadget架构中,出现backing storage一词:

backing storage,中文可以翻译为备份存储器,但却还是不知其为何意。

网上找了一下,找到这个解释:

http://www.gordonschools.aberdeenshire.sch.uk/Departments/Computing/StandardGrade/SystemsWeb/6BackingStorage.htm

“Backing storage devices are where you can store data permenantly. This means that data is held when the computer is switched off and can be loaded onto a computer system when required.

The hardware that stores the data are called backing storage media. The media are put into backing storage devices.”

简单总结一下就是,backing storage,备份存储器,就是Non-Volatile,非易失性存储器,断了电数据不会丢失的存储器

常见的Backing Storage有软盘Floppy Disk Drive,CD-ROM drive,USB Flash Drive,DVD-ROM Drive,Hard Disk Drive等。
