rsync over ssh - existing files are not updated?

[Sjon Hortensius]

Hi,

I am using rsync to backup various machines to a central server (all 
archlinux, rsync 3.0.7 on ext4). Yesterday I needed one of those 
backups, and I found out it is useless since a lot of files never got 
updated. Even when I enable checksums some files are not updated. I am 
pretty sure I am missing something, but am not sure what it is. This is 
(a stripped version of) the command I use:

rsync --stats -vvvvvvv -xaz --append --delete-during --delete-excluded 
/etc/profile.d backup at server:client/etc/

In this example, the server has an older version of the file 
'mozilla-common.sh', but this file does not get updated. I have attached 
the logfile of this command.
With checksums enabled, some files are touched, but the 
'mozilla-common.sh' file is not. I have attached this log as well.

This is what the directories look like after syncing:
