You got any virtual machines? I’ve found previously that TM doesn’t play nicely sometimes with the big VM files and hence any changes mean the whole VM needs copying again...It seems Time Machine is backing up just under 7GB of data every hour. Is there a specific scenario or two that might cause this to happen?
No, this is a new computer and I'm not using any VMs. I wanted this one to be clean with no issues. But for some reason, every Time Machine backup is 6.85gb, 6.88gb or very close...You got any virtual machines?

I have 2.72 TB available of 3.11 TB...When you go to "about this Mac" what does it show for hard drive use under the "Storage" tab?
I don't think I have "all my files" anymore as I'm on High Sierra. When I looked in Terminal there are just thousands of files scrolling so I'm not sure what to do there. The same exact scenario happens with my MacBook Pro and I figured getting a new computer and not restoring from a backup would fix whatever it is. I was wrong. It's not the end of the world - just very strange and kind of annoying. I wish Time Machine would just backup what has changed since the last backup an hour earlier...You could also check if you have large recently changed file(s) using Finder's "All My Files", sorted by date.
I'd use Terminal and type "sudo fs_usage" to see just which files are being written during a session (stretch the window wide to see full pathnames).
Mine is 396.78...When you go into Time Machine Preferences, and then click on "Options..." what does it say your estimated full backup size should be? For me, my backup says a full backup is 56GB, but my Time Machine backup is 74GB due to system and file changes over time. Usually when Time Machine runs, the backups are pretty small.
Mostly photos, then videos...3.11TB - 2.72TB is about 400GB, so it sounds like your backup is ending up as the right size. It is odd that each hour 7GB is being moved around. I can only guess something is indexing your files, but it's hard to know. What makes up the majority of your storage--photos, videos, other?
Not sure what you mean...Cloning rules OK?
I have a feeling this may be what I need to do - but I don't want to stop backing up photos and videos. If I do add a photo or video folder to the Time Machine exclusion list - will it retain the backups I've made so far? If so, then this will be okay as worst case scenario I can go back and restore from an old backup...I’ve seen behavior like this out of TimeMachine before. It turned out to be a single corrupt file that every time TimeMache tried to copy it it crashed the backup process, then it would start backup from there and hit the same file the next time. It really would have been nice for a dialog to tell me which file was bad, but no I had disable backups on a folder by folder basis until I found it.
For me it was a corrupt video file in what was my iPhoto library at the time. I’d start by disabling backups of your media folders one at a time and see if you can narrow it down to specific large folder that won’t backup.
Looks interesting. I'll add that to my possibilities...
Do these options work similarly to time machine where they don't backup everything? Only what has changed? That is my preference...Try either CarbonCopyCloner or SuperDuper.
Once a day with either should be fine.
And your backups won't continually "grow" in size.
You just temporarily add it to the exclusion list. It will leave the existing backups in place. Once you figure out which file is corrupt and remove or fix it you remove it from the exclusion list and it picks right back up.I have a feeling this may be what I need to do - but I don't want to stop backing up photos and videos.

What I'd like to have is CCC backup my Mac, incrementally, on a daily basis. But it won't do this automatically because the Airport Extreme hard drive is not mounted.Unless you're doing mission-critical work that must be backed up every hour or so, I'd suggest doing the CCC incremental backups once a day, and be done with it.
If you don't need the backup drive connected "in between", just disconnect it or turn it off.
You might try adding the remote hard drive as a login item. Go to SystemPreferences/Users&Groups/ (your login name) /LoginItems ... then click the "+" button to add and select the disk from the pull-down list.What I'd like to have is CCC backup my Mac, incrementally, on a daily basis.
