Internal backup – instead of "max compression" use 7z?

I just found the function "Backup", great!
It really should be promoted!

But whynot just maybe make auto 7z if max?
I mean the max in itself doesn't do anything really for size.
Or recommend 7z instead, as it's actually less slow than max while much better compression!

I tried it with "App Data" (as the exe:s I can get anytime).
My data is 99.9% ThunderBird mails, so YMMV.
System: i7-2600-3.40GHz, 8G RAM, 64b W7.

MaxCompressionNo 7zNo = 3min48s = 2.22GB
MaxCompressionYe 7zNo = 6min19s = 2.20GB
MaxCompressionNo 7zYe = 5min08s = 1.64GB
MaxCompressionYe 7zYe = 8min08s = 1.58GB

It will vary quite a bit depending on the files you're backing up, so we leave it up to the user. I recommend just using 7z without Max personally. We default to plain zip since it's accessible via all modern Windows without an app.

Sometimes, the impossible can become possible, if you're awesome!
