No. The program that is still running is the executable program and the 
libraries which were installed at the time the program was started, i.e. 
before the upgrade. This is still running in the RAM of the machine, 
while the executable and libraries on the disk may be a new version 
already. Only if you want to use the new version of the upgraded 
program, you have to restart it.

I'm not sure about backups though. I suppose there it depends on the 
backup program if you could get troubles.
