How do I manage when Emacs creates backup files?

I can't seem to find information about when Emacs backs up. It usually works fine, but today I lost part of the file due to an incomprehensible callback to Magit and after looking at my backup directory I did not find any of the files that I worked on today. It seems that everything was hard in the previous days.

Emacs creates backups when visiting files and automatically saves periodically when you edit - the manual (linked above) details everything that needs to be changed to make this process more aggressive. Unfortunately, pressing v in the status buffer for magit does not count as visiting or editing the file, but note that the patch has been fixed before magit to ask for confirmation before returning.

Generally speaking, Emacs will save every keystroke in the backup files, by default with the name #foo# , if your file is named foo . See this AutoSave entry in the Emacs Wiki for more information.

And / or find here [emacs] backup or [emacs] autosave , as discussed earlier.

Emacs does not back up the file when VCS takes care of this. He believes that git / cvs / svn will take care of the backup mechanism.

Please also note that magit 0.8 was released with a confirmation before return: you need to add

 (setq magit-revert-item-confirm t)

in your .emacs for protection.
