WD Bkup Software

Just installed a My Book, 5 TB, & bkup software. System is Win 10 Pro with 2 physical drives: C; is an ssd, single partition.
2nd physical drive has 2 logical partitions: D: & E;

I want to backup all (3) partitions but I seem to be able to select only one. Is there a way to backup all 3? Pro version of software? Another software package?

Hello there,

If you see the to the left on the software, i am assuming you are using Smartware, you can see the backup source, there is a drop down menu that lets you select the drive you would like to backup, you should be able to see the partitions there.
