Instead of copying files within a filesystem, a copy of the whole filesystem itself can be made. This is also known as a raw partition backup and is related to disk imaging. The process usually involves unmounting the filesystem and running a program like dd (Unix). Because the disk is read sequentially and with large buffers, this type of backup can be much faster than reading every file normally, especially when the filesystem contains many small files, is highly fragmented, or is nearly full.
