Hi prad,

editors can produce backup files - eg emacs adds a ~ to the backup
file. the backup file keeps getting changed as you make changes to the
original so you i'm wondering what the point of them is.
Please refer to the Emacs manual (info m Emacs) to learn about the
precise rule governing backup files. Just like you, I do not like to
have all of these backup files springing off everywhere in my
filesystem. Instead of turning backup off, I tell emacs to put them in
the `.emacs.d/backup' I created for this purpose:
(setq backup-directory-alist '((".*" . "~/.emacs.d/backup")))
You can get a finer control on backup location, read documentation for
the bariable `backup-directory-alist' to discover how.
Note that this setup tends to produce super long file named in
`~/.emacs.d/backup' which may break some fragile systems (e.g. I
encountered problems when preparing ISO filesystems not supporting
these long names).
i turn off backups (so my directory doesn't fill up with ~ files), but
then i also don't space things properly and occasionally use cryptic
names when programming (from what my son tells me), so i figure i
should change some of these bad habits.
how do people make use of the backup feature when they program?
Note that basic functionalities of RCS systems are well integrated in
Emacs (see the Tools menu), and I systematically use SVN (in the
ports) as a sophisticated backup system when I edit files that count.
Note that the FreeBSD wiki features an intereting comparison of the
various RCS systems available, so if you are interested with this
approach, you can look for this comparison and make your choice.
You can also use RCS without the (moderate) hassle to set up a
repository, Emacs has support for an `immediate' RCS system, doubling
the files you want to keep track of with a `,v' companion file,
containing revision history. (IIRC, this RCS system is the ancestor of
CVS, but I cannot find again the name, sorry about this.)

All the best,
