Single or Numbered Backups
..........................

   If you choose to have a single backup file (the default), the backup
file's name is constructed by appending `~' to the file name being
edited; thus, the backup file for `eval.c' is `eval.c~'.

   If you choose to have a series of numbered backup files, backup file
names are made by appending `.~', the number, and another `~' to the
original file name.  Thus, the backup files of `eval.c' would be called
`eval.c.~1~', `eval.c.~2~', and so on, through names like
`eval.c.~259~' and beyond.

   If protection stops you from writing backup files under the usual
names, the backup file is written as `%backup%~' in your home directory.
Only one such file can exist, so only the most recently made backup is
available.

   The choice of single backup or numbered backups is controlled by the
variable `version-control'.  Its possible values are:

`t'
     Make numbered backups.

`nil'
     Make numbered backups for files that have numbered backups already.
     Otherwise, make single backups.

`never'
     Never make numbered backups; always make single backups.

`version-control' may be set locally in an individual buffer to control
the making of backups for that buffer's file.  For example, Rmail mode
locally sets `version-control' to `never' to make sure that there is
only one backup for an Rmail file.  Note: Locals.
