dump (Unix)
 | This article includes a list of general references, but it lacks sufficient corresponding inline citations. (March 2010) |
dump is a Unix program 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]
