UrBackup does the opposite of deduplication

Hello,

unfortunately, Urbackup seems to do the opposite of deduplication here.

I have about 7TB of Data on my Linux machine. Of that, I have excluded quite a bit from the backup in the settings. Nevertheless, the progress bar under activities on the Urbackup Server (W10) shows me at 126Gb of 16.65TB.

My settings (File Backup):

Excluded Files: /mnt2/;/media/a8af3832-48c7-4568-861f-e80380dd7e0b/Video/;/media/a8af3832-48c7-4568-861f-e80380dd7e0b/Backups/;
Default included files (last point in the GUI. German "Standardmässig enthaltene Dateien): ;/media/a8af3832-48c7-4568-861f-e80380dd7e0b/;

My mounts:

sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)
proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)
udev on /dev type devtmpfs (rw,relatime,size=10240k,nr_inodes=2556447,mode=755)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)
tmpfs on /run type tmpfs (rw,nosuid,relatime,size=4095060k,mode=755)
/dev/sdb1 on / type ext4 (rw,relatime,errors=remount-ro,data=ordered)
securityfs on /sys/kernel/security type securityfs (rw,nosuid,nodev,noexec,relatime)

rpc_pipefs on /run/rpc_pipefs type rpc_pipefs (rw,relatime)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,relatime)
/dev/sde on /media/a8af3832-48c7-4568-861f-e80380dd7e0b type btrfs (rw,relatime,space_cache,subvolid=5,subvol=/)

/mnt2 is a symlink to /media/a8af3832-48c7-4568-861f-e80380dd7e0b/

but I have excluded /mnt2.

What am I overlooking?

Greetings,
Hendrik

Hendrik,
In UrBackup storage folder, which folders got copied for this machine? And in default included files, is the first semi-colon there for a purpose?
