18.6 Auto-Saving: Protection Against Disasters
==============================================
From time to time, Emacs automatically saves each visited file in a
separate file, without altering the file you actually use. This is
called “auto-saving”. It prevents you from losing more than a limited
amount of work if the system crashes.
When Emacs determines that it is time for auto-saving, it considers
each buffer, and each is auto-saved if auto-saving is enabled for it and
it has been changed since the last time it was auto-saved. When the
‘auto-save-no-message’ variable is set to ‘nil’ (the default), the
message ‘Auto-saving...’ is displayed in the echo area during
auto-saving, if any files are actually auto-saved; to disable these
messages, customize the variable to a non-‘nil’ value. Errors occurring
during auto-saving are caught so that they do not interfere with the
execution of commands you have been typing.
