Have a look at the initramfs doc to get brief idea: http://www.mjmwired.net/kernel/Documentation/filesystems/ramfs-rootfs-initramfs.txt >From what I've understood, is that backing device/store is the device onto which _committed_ data is actually written. This might be a block device like a hard-disk, flash mem or even the RAM (used by in-memory file-systems). CMIIW.
