Have a MacBook 12" and when I backup manually Time Machine always backs up the entire hard drive as if it's the first backup. I do not back up automatically only when new files are added. Does not seem to happen on my Mac Pro!.
MacBook Pro with Retina display, OS X El Capitan (10.11.3)
Your profile is showing OS is El Capo.. is that still correct?
How do you know it is backing up the entire contents?
Please open the console and type backup into the search.. this will give you the log messages from Time Machine.. and it will help you (maybe) see the precise issue.. and how much it is backing up.
If it is backing up the entire disk every time your Time Capsule should be full to bursting with the sparsebundle from the 12" .. check the size.. does it make sense.. and how much history does it have in it. Or is it in fact replacing the backup each time?
If you have upgraded to Sierra or High Sierra.. strongly recommend NOT using Time Machine as it is unreliable.
I moved to Carbon Copy Cloner a while ago.. and it works very well.

Console should have a whole heap of messages from TM.. something is seriously wrong if there is nothing..
If you mean there is no relevant info that is different but there must be messages.. heaps of them.
I am attempting at the moment to see if TM will work reliably to a USB drive on a high end Asus router.. it has taken me a bit to get it running but I would say has the same issue as TC. These are console messages.

Glad to see you take backup seriously I was doing the same.. both CCC occasionally and TM as per default hourly.. then my annual deletion took place.
At this point.. seeing as the TC virtually touches the computer.. and there is no question of poor connection.. I swapped from TM to CCC as regular backup.. CCC has excellent messages.. I know when it fails and why.. unlike TM it keeps me informed.
eg.
CCC was unable to mount the destination network volume due to an invalid username or password.
It is so easy to give a message but no.. TM just one day ups and deletes.
And yet your other computer TM is running fine.. quirky isn't it..
Plus your backups from 2015 is excellent.. imagine TM not corrupting itself for 2 years.. outstanding.. !!
Thanks for the heads up. Have done as you said but no information is displayed. Also use CCC and have for years as a failsafe every couple of weeks. Have set up for automatic backup and seems to be working as it should. Still not convinced about Time Machine as I have read it does not backup the OS?. Just keep using both but CCC more often. Funnily enough have installed High Sierra on the Pro but seems ok.
Keeps backing up all hard drive contents
