New WD My Passport ultra 2TB with WDsmartwarepro

Why is it that the files in my source folders i.e. on my main hard internal drive are not the same as those backed up in the target drive?  The folder WD Smartware.swtor does not reflect the files I have deleted on the main internal drive, is this normal.  My expectation was for a  mirror copy and sync of the files I intend to keep.

Should I need to recover my existing files as I wont it at that present time, it would be confusing to filter out all the deleted and changed data.   I guess I have been fortunate not to be in this position.

In the past I have simply made a new folder and copied the entire drive, this is time consuming and rarely a regular task, except for a seagate which had an external press button and backup express mode which copied only the files which had changed.

Hello,

Please note that the WD Smartware is not a synchronization software. Since you deleted files on your computer, the information on both drive won’t be the same.

Sorry but I’m not understanding the rest of the questions.
