UML_MOO(1)

NAME
uml_moo — merge a COW file with its backing file

SYNOPSIS

uml_moo [COW file] [new_backing_file]

DESCRIPTION

This manual page documents briefly the uml_moo command.

This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. Instead, it has documentation in HTML format; see below.

uml_moo is a program to merge a COW (copy-on-write) file with its backing file, and write the result to a new backing file. This can be used periodically to update the backing file with the changes made in the COW file.

NOTE: you can save a lot of disk space using COW files. When checking the size of the COW file in order to see the gobs of space that you're saving, make sure you use 'ls -ls' to see the actual disk consumption rather than the length of the file. The COW file is sparse, so the length will be very different from the disk usage.
