Changing Drive Letters of Data Update to my previous update: I was wrong. After moving the data to a different drive and kicking off the backup, it did recoginze that it was the same data and it did an incremental backup like it was supposed to do. I am thinking that the first backup I ran after the move took longer because the backup job had been paused for a week and there may have been more files to backup than normal. Or, maybe it had to process the moved files to verify that they were already backed up. Just guessing, but the new format appears to be smart enough to figure out that data has been moved and you are backing up the same data.
