File Synchronized Before it's 100% Saved

[Rhino]

Ye, what I tried last time and it didn't seem to work but tried it again just now with different time settings and it still seems not to be working... If the time is set above the time it takes to fully save the file, then nothing is backed up, even if the file is different from what it was before (ie, new object in it or old object deleted from it etc). The only time when it backs up anything is if you set the time lower than the time it takes to save the file like 10secs and then it backs up a file, but the file it backs up is only the 1/2 saved file which is corrupted if you try to open it...
