"Do nothing" is not a computer program, but it is the most widely used backup strategy. There are no initial costs. There is no backup schedule to follow. Just say no. If something happens to your data, grin and bear it!
If your time and your data is worth little to nothing, then "Do nothing" is the most suitable backup program for your computer. But beware, Unix is a useful tool, you may find that within six months you have a collection of files that are valuable to you.
"Do nothing" is the correct backup method for
/usr/obj and other directory trees that can be exactly
recreated by your computer. An example is the files that
comprise these handbook pages-they have been generated from
SGML input files. Creating backups of these
HTML files is not necessary. The SGML source
files are backed up regularly.
