Incremental backup from USB drive too large
I've configured ATI2019 to create an incremental backup of 3 drives:
D:\ (Internal HDD)
E:\ (External USB)
X:\ (External USB)
However I also get way too large incremental backup files.
I already checked that "sector-by-Sector" is NOT activated and defragmentation is also switched off.
The backup settings are like the ones in the screenshot attached.
Does anyone have a clue why the incremental files are still too large?
