DietPi-Sync Dry Run All Wet?

[midnightwatcher]

I'm using v6.17.12 (Native PC - x86_64). I noticed that sometimes a DietPi-Sync dry run took an awfully long time, as though it were doing an actual backup. Also noticed the error below (snippet from the File Viewer):

1,316,629.58 (DRY RUN)
2018/11/09 05:11:04 [23143] rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1196) [sender=3.1.2]

2018/11/09 05:11:04 [23165] *deleting .dietpi-sync_stats

Are there any known issues with DietPi-Sync?

/tmp/DietPi-Sync/n

Could you cd to the directory above?

If its there check the permissions, if not create it and try again.
