How can I update my 6603 an retain root?

So I have an xperia update alert. Is there a way to update to the latest and retain my files as well as root access?

No. If you are on KitKat flash a pre-rooted Lollipop.
If you upgrade you can root only if you unlock the bootloader. It is the only way to root Lollipop directly.
There is no sense to upgrade, then downgrade to root. Do that now, since you are on KK.
In short : Do not upgrade officially, upgrade by flashing a pre-rooted Lollipop. You can do that even with an locked bootloader with Flashtool. Find an appropiate ftf.

I'm not on KK, Im on lollipop but I believe there's a newer version to LP for the Z3. I'm on 23.1.A.0.690

What size is it? Maybe it's not a firmware update.

It's an Xperia system update I can't pull up details about it without beginning the install process

you would have to flash a pre-rooted flashable rom to retain root, ota updates generally tend to kill root

Thanks, I've been a little out of the game when it comes to flashing and rooting. I rooted my phone about a week ago and put lollipop on it. I assumed it would be the case that i'd have to flash the updated version I just wondered about retaining my files because i've gone through a bit of trouble debloating and tweaking the phone.

you'll most likely have to go thru that process again of debloating depending on what rom you install as it will most likely put most of the stuff you have removed back into the system

I suppose I don't mind debating again but what can I use to make a backup of my apps and app data? to then restore once updated... are there any full proof tools?

There are loads of tools for this, probably the most well known in titanium backup
