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.
