Copyright © tutorialspoint.com dump [-W | -w] On media that
cannot reliably return an end-of-media indication (such as some
cartridge tape drives), each volume is of a fixed size; the
actual size is determined by specifying cartridge media, or via
the tape size, density and/or block count options below. By
default, the same output file name is used for each volume after
prompting the operator to change media. files-to-dump is either
a mountpoint of a filesystem or a list of files and directories
to be backed up as a subset of a filesystem. In the former case,
either the path to a mounted filesystem or the device of an
unmounted filesystem can be used. In the latter case, certain
restrictions are placed on the backup: -u is not allowed, the
only dump level that is supported is 0 and all the files and
directories must reside on the same filesystem. |-level#||The
dump level (any integer). A level 0, full backup, guarantees the
entire file system is copied (but see also the -h option below).
