Here's what I do.
I received 2009 on an 80G drive, 2009.5 on a 160G Drive & 2010 on a 160 G Drive. I installed 2009 on the C and put the drive in the drawer. I installed 2009 to the C and put it in the drawer. I erased the 80G and use it as a backup for my songs. I installed 2010 to the C AND updated the older 2009.5 drive to 2010 put them both in the drawer. I now have TWO copies for backup and they just sit in the drawer.
Next update I will do the same. Erase one of the 160G drives and update one to the next. This way I'll always have two backups and I'll accumilate drives for son storage and backup as well.
