Hi Séverin
That was my first thought (data added by users), but when I saw the graph it was clear that nobody was working during the night, so I looked somewhere else.
Actually I checked every backup related setting, and it came up that there was kind of double backup in place.
The key setting was 'Automated backup storage'. It's value was 'Course backup filearea and the specified directory'. The correct value should have been 'Specified directory for automated backups'.
I simply misread this setting, sorry to bother you all guys!
Now I just need to cleanup the filearea... Moosh will be handy.
Thanks again
