I am using rsync on my low-power NAS to backup my server to it. I just found this warning in the logs, which I do not understand:

There are two confusing parts in here:
This line does not make sense to me, because ´daily.0´ should already exist due to the previous rsync-command. Why is this needed?
[09/Jan/2019:00:39:51] touch /mnt/vg_bkp_disks-lv_bkp_data/backups/daily.0/
Furthermore, what does this line mean?
[09/Jan/2019:00:39:51] No directory to delete: /mnt/vg_bkp_disks-lv_bkp_data/backups/_delete.793
Apparently, this does not cause any issues, but since this message occurs on the NAS and the previous rsync-command ran successfully, it seems strange, because rsnapshot on the NAS should have created it in the first place?! (since it is obviously a tmp-file of either rsnapshot or rsync)
Am I correct in assuming that the actual warning at the end is caused only by this call to my wake-up script on this line and everything else ran fine?:
[08/Jan/2019:23:45:05] cmd_preexec "/root/wake_kerbert.sh" returned 1
