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。
