rsnapshot produces a double backup of localhost/media

Question

I use rsnapshot in my Xen host to backup all vms via their snapshots.

Now rsnapshot backups everything double, because it creates an extra "localhost" folder in each daily backup, that contains everything in /media/snapshots again.

for example those are the same files:

/backup-sda4/rsnapshot/.sync/localhost/media/snapshots/tmp-vm01.myserver.de-var/backups/mysql

and

/backup-sda4/rsnapshot/.sync/vm01/media/snapshots/tmp-vm01.myserver.de-var/backups/mysql

This is my config:

config_version  1.2
snapshot_root   /backup-sda4/rsnapshot/
no_create_root  1
cmd_cp      /bin/cp
cmd_rm      /bin/rm
cmd_rsync   /usr/bin/rsync
cmd_logger  /usr/bin/logger

retain      daily   7
retain      weekly  4
retain  monthly 3

verbose     2

loglevel    2

logfile /var/log/rsnapshot.log

lockfile    /var/run/rsnapshot.pid

rsync_long_args     --delete --numeric-ids --relative --delete-excluded --stats

sync_first  1

backup  /root/      dom0/
backup  /etc/       dom0/

backup  /media/snapshots/tmp-vm01.mysqrver.de-var/www/    vm01/
backup  /media/snapshots/tmp-vm01.mysqrver.de-var/backups/mysql/  vm01/

There is no mention of localhost in the config.

How do I prevent the extra localhost backup? is this default somehow?

This ist my /etc/cron.d/rsnapshot

30 4    * * *           root    /usr/bin/rsnapshot sync && /usr/bin/rsnapshot daily
0  4    * * 1           root    /usr/bin/rsnapshot weekly
30 3    1 * *           root    /usr/bin/rsnapshot monthly

It seems like the files in .sync/localhost were created previously in an early stage of the server and are not being deleted by

rsnapshot sync

in the cron job. It seems like rsnapshot sync only syncs existing defined backup directories in rsnapshot.conf, but does not delete folders, that are not defined there. To me this seems a bit buggy, I posted it also here:
