What led my here:

I've been searching for days trying to figure this out, and all over the internet I see an array over answers.  Unfortunately I think Microsoft changed the way you can backup from Windows version to Windows version, taking out features and adding new ones, and then sometimes adding back old features, just depending on the version of windows you have (7, 8, 8.1, 10, 2008 server, etc).

 

My setup:

I have 3 hard drives connected to my system:

B:\ - this is my backup drive, 4 TB USB external drive.

C:\ - this is WIndows and my programs - SSD drive 150 GB

D:\ - this is my data drive, 4 TB internal

 

My Dilemma:

Now back track a little, before I had the B: drive, I've been doing this successfully with only backing up the C: drive onto the D: drive, using wbadmin in task scheduler using the following twice a week:

wbadmin Start Backup -backupTarget:D: -include:C: -allCritical -quiet

 

This worked good, the backup I think just replaced the old backup and took about 20 minutes because the C: drive is only like 80gb.

 

But...... recently my D: drive failed, and I realized that I need to backup both C: and D: onto another drive dedicated for only backups.  So I got a new drive for this purpose (the B: drive) and changed my task to show as follows:

wbadmin Start Backup -backupTarget:B: -include:'C:,D:' -allCritical -quiet

 

This works, but the problem is backing up the D: drive to the B: drive takes like 24 hours!  This would be fine if it was a one-shot deal and after the initial backup it just backed up incrementally. But its not okay if I have to do this every single time I backup. Notably its bad because if something goes wrong during that 24 hours, or I simply reset the computer for any reason, then nothing is backed up, and I'm left with nothing! 

 

What I want to do:

I want to backup my C: and D: drive on to my B: drive. I want them to be disk images / full backups, exact clones of what is on the C: and D: drives.

 

So my question is:

Can wbadmin be used to incrementally backup in windows 8.1? If not, how can I schedule an incremental backup in windows 8.1?

I personally don't like incremental backup. I got caught once when my drive got infected, or corrupted and the backup image was updated with the the error. I did not have a clean BU. image so, had to re install OS and software. I could recover my data successfully though.
