The dump command is a program on Unix and Unix-like operating systems used to back up file systems. It operates on blocks, below filesystem abstractions such as files and directories. Dump can back up a file system to a tape or another disk. It is often used across a network by piping its output through bzip2 then SSH.
A dump utility first appeared in Version 6 AT&T UNIX.[1] A dump command is also part of ASCII's MSX-DOS2 Tools for MSX-DOS version 2.[2]
