This Visual basic script is an incremental backup calculator. It can be pointed to a drive letter or path, given a date range, and will calculate the number and total size of files modifed in that time period. This is extremely useful to run against your network to determine the worst case backup size when doing incremental backups each night. We suggest running with a 30 day date range, then dividing by 30 to determine the average size of files changed per day. More documentation and screens shots.
