Intellispace centers on the paper, not the printable area, so that does exactly what you are asking for.  Now, if you've already sized your print to "Fit to Page" and your non-printable margins are not centered, realize that it is impossible to center the print on the paper.  That is, if the printable area is not centered, you have to use some of the printable area in order to counter the uneven non-printable margins.  So if you haven't filled up your printable area and there's slack to work with and your print is big enough (not just one small print), Intellispace centers on the physical paper.

Long story short: if you set placement to Intellispace, it'll always center as close as possible to the center of the physical paper.  If it isn't centered, it isn't possible to center a print that large on the current paper/driver setup.  Think of it this way, if you fill the entire printable area by sizing "Fit to Page", you can't move the print: there is nowhere else but that one spot to print a print that large.  You can't move it down to center it: because everything below the print is non-printable area.

There's no "backup" feature as such in QU other than saving various settings as Fred has described.
However, one option is for you to manually save these folders to another HDD:
C:\Program Files (x86)\Qimage-U
C:\ProgramData\ddisoftware\Qimage
The latter is the most important as the program can always be re-installed

The Program data folder can be saved from within QU by using Utilities - Migrate/Copy Application Data ..
At the end of the copy process it asks if you want to use the new location or leave it as a backup.

I'm pretty sure QU is unlikely to be dying soon.Q One was, I believe was produced  to help MAC users particularly to save them running a special Windows system on their MAC's. Most of them would use other software to process images but Windows users with QU have the advantage of a sophisticated raw processing and editing system as well as full set of features for printing.
Let me mention some advantages of using QU:
Deep focus sharpening for raw image processing and editing as well as printing.
The ability to add Print filters, useful say, if your profile is not performing quite as you'd like it - increase saturation, fill shadows a little, tweak colour balance.
Print mattes = uneven borders, I don't think Q1 has that yet.
Load and re-name images from your memory card.
Albums, Database.

What you need is back up software and separate hard drives(s) to back up to.
Fred and I use Easus Todo software: -

I use the Home edition, I think Fred has the Workstation edition.
I have a set schedule which backs up my SSD C-drive and Data D-drive in various combinations every day. There's daily & weekly schedules to different HDD's. Each new backup overwrites the old one and there's always one that's a month old.

Yes there is and QU has a special JOB included which sets up QU for target printing.
See attached screen shot.
Click the Recall icon, select "J" for job and scroll down to {Q} printer target setup.job.
Edit:
I've added a screen shot of QU settings for a target I printed in January
