autosave saving any file opened, even if it hasn't been changed.
Particuarly noticeable when working over a slow network link.
To reproduce, enable autosave
open at least 2 files
change one of them
wait for the autosave to activeate
check to see what backup files exist for the opened files, there will be one for each opened file, not just the file that was changed.

autosave is saving any file opened, changed or not
the autosave is saving any file opened, even if it hasn't been changed.
That is by design.
The autosave is nothing more than a periodic backup that runs with an interval defined by the interval value found in the Backup panel of the Editor Options dialog.
I don't see any way around this.
Consider a file that is changed greatly and then saved. Lets say that pattern repeats several times. If the backup only processed files if that file was currently modified it would miss all those changes.
Now the whole backup could be made more compilcated by checking timestamps etc, but that sort of backup is better handled by source control.

If it is causing an issue it can be turned off with a 0 interval value.
A second option would be to handcraft a backup policy using a script, an example of which can be found here:
