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.
