Howto deduplicate full disk just converted from jhfs+ to apfs?

[toke lahti]

The 4TB drive is full of system disk images and iOS backups.

Looks like there's quite a few 3rd party tools and none from Apple?

Wondering if there is any way to trust these 3rd party tools?
(Just installed "fclones"...)

I'd guess that with fclones, I'd have 716GB of more free space to that disk?

Anybody have experience with diskDedupe (from appstore)?
Or heard about any problems?
