It wasn't a hardware fault though. You don't replace hardware when you have a software problem because if you got a replacement, it would do the same thing.

You will have experience working with computers and filesystems though so you should only weigh their suggestions into what makes sense to you.
If you look at the bottom of a Finder window when your main drive is selected or choose file > get info when the main drive is highlighted, it tells you how much space you are using. This is how much the computer is trying to backup so if you only have 200GB used and it is filling 1TB, you know something isn't right.
Look for your Parallels disk image and check what size it is. If it is 20GB and your backup is done daily, Time Machine will try to store incremental versions of those files so could store 14 x 20GB = 280GB after a week, which it doesn't need to do.
So, you just exclude the Parallels disk image from the Time Machine backup process and that should sort the issues. No more slow backups, no more filling the 1TB drive etc. There may be other large files doing a similar thing. If you have used over 600GB of your internal drive, don't use Time Machine, use the above program instead.
Support staff are paid to follow guidelines so they recommend what they are told to recommend as they are acting on behalf of the company. Their suggestions won't necessarily be the best ones in a given situation.
Are you trying to use Parallels in the same way you used your old PC? For example, did you create the Windows drive with a large size? Even if you had an old PC with a large hard drive, you wouldn't make the Parallels one a large size. You should only make it 50GB at most. You also shouldn't get into the habit of running Windows software that you used to use unless you absolutely can't find a Mac equivalent.
List all of the programs that you run under Windows and need to use Parallels for and people here can offer suggestions for Mac equivalents. You may not even need to use Parallels at all.
