Short version:

656G used (df -h)
450G used (du -sh)
10G used by snapshots
196G discrepancy <-----

I don't undertand what is using 196G.

df -h /mnt/dati/
File system            Dim. Usati Dispon. Uso% Montato su
/dev/mapper/vg00-dati  919G  656G    262G  72% /mnt/dati

du -sh /mnt/dati/folder1,2,3

I have a subvolume with 10 snapshots.
I know that 10G of data has been copied, so snapshots should hold no
more than 10G.

There's not a huge amount of metadata:

btrfs fi df /mnt/dati
Data, single: total=774.00GiB, used=654.42GiB
System, single: total=32.00MiB, used=92.00KiB
Metadata, single: total=2.00GiB, used=1007.42MiB
GlobalReserve, single: total=512.00MiB, used=0.00B

Why such a big difference between 'df -h' and 'du -sh' ?
