I have a job that backs up our exchange server and 4 other servers (fairly small). Up until this week, the full backup jobs on Friday's ran about 494gig, and the diff jobs ran around 65 - 75gig. Starting this week, however, the diff backups are running 408gig. Every time. I have checked the servers, and there is no extra data on them to account for this.
What do I need to check to see why this is happening all of a sudden?
