What makes you think that the df output is incorrect? That sda1 is 73%
full and sdb1 93% full?

What makes you think that the du output is incorrect?

The "binaries contains only the data folder" case repeats itself in
the following pairs - and it is not necessarily wrong because it
simply implies that .../server only contains default, .../binaries
only contains data, .../76/b4 only contains 4d, etc:
