there is a new plugin: Backup Copy.
It creates a backup copy of the current file in Geany when it is
saved. You can specify the directory where the backup copy is saved and
you can configure the automatically added extension in the configure
dialog in Geany's plugin manager.
This plugin can be used as a poor man's version control system as it
saves previous states of a file which can used later again or used for
generating diffs against the current file.
Another use case is to set the save path to another partition than the
one where the file is saved and then it provides backup functionality.
It requires a recent SVN version of Geany to compile and load, at the
time of writing, revision 2604 should be good.
(needs Geany 0.15svn_r2604)
