Storage Craft backup too large - comparison tool

Have a Windows 2012 Standard 64-bit Server, with StorageCraft v5.14

If I run an incremental backup during the day the file size is less that 1gb.  If the incremental backup runs at its 8am scheduled time it is over 7.5gb.  I have picked over the event log for any conflicting processes, and rescheduled them all.  Now after the backup runs, a defrag (if the drive is over 30% defragmented) runs AFTER the backup.  If I compare the (2) different backups, the files and folder sizes are within .5gb in size.

Is there a comparison utility / tool out there, that I can use to compare these .spi files (and/or md5 files) to see why there is such a huge difference.  General concensus is that there is some process running at night that is causing this.

Goal:  I want to bring the file size down, so it is feasible to use the ImageManager to transfer the .spi file offsite.

There is no such open-free tool that can do this. Maybe SC engineers can give you some development kits for this.
As for the file size. Is there compression enabled on your server? Or encryption?
Your guess about defragmentation is correct. Are you sure it is disabled between two incremental runs?
Note, if you take full then defrag then incremental - increment will big big. I think you know this.

Have gone back and forth with StorageCraft for awhile now, that is why I am now seeking other help.  Have done everything they requested.

The only file compression and encryption is being done per user, on individual files and by StorageCraft.

The defrag is kicking off after the backup completes.  That is, if you can believe the Server Even / Log Files.

The full was only taken in the very beginning.

Your help is appreciated, and hopefully, someone else out there, has come across this.

Can you keep Defrag off for 2 days and see if the size changes? Or have you done this already?

Thanks for feedback. I was trying to understand if you do always a new full backup after defrag and then increment. Because if you do once increment and then defrag - no difference before increment or after - it will be always bigger than it should be. Because increment compares the data or sectors changed and defrag changes the position of data.

noxcho is right.  Your backup software was looking at the drive bitmap, which changes when you defrag.  nice work noxcho!
