Hello. Before I got rid of my SR MBP (2007 model) running Leopard in April, I used SuperDuper to create a clone backup on an external hard drive. Moreover, I used Time Machine to make a backup on an additional drive. When I got the MBP 2010 model (running Snow Leopard), I used migration assistant to move the stuffs originated from my SR MBP to the MBP 2010. It has been 2.5 months and things "seem" to be running fine. Is it ok to remove the backup made by Super Duper and use the drive for other purposes? (For example, clone the new MBP HD or use it to backup my PC, etc). Can you think of any situation that I should still keep the backup made by Super Duper? Thanks.
